A palavra prosodica no portugues brasileiro : o estatuto prosodico das palavras funcionais / The prosodic word in brazilian portuguese : the prosodic status of the functional words

Toneli, Priscila Marques, 1982- 13 August 2018 (has links)
Orientador: Maria Bernadete Marques Abaurre / Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Estudos da Linguagem / Made available in DSpace on 2018-08-13T08:48:54Z (GMT). No. of bitstreams: 1 Toneli_PriscilaMarques_M.pdf: 3123769 bytes, checksum: 58ea18b760026022b27899d26b55ad85 (MD5) Previous issue date: 2009 / Resumo: Nas línguas, há vários elementos que são difíceis de classificar, principalmente no que se refere ao seu estatuto prosódico, e as palavras funcionais são um desses elementos, pois enquanto as palavras lexicais são sempre Palavras Prosódicas, já formadas no componente lexical, recebendo acento lexical, as palavras funcionais exibem um padrão variável entre as línguas, podendo se apresentar como clíticas ou como Palavras Prosódicas (cf. Selkirk 1984, 1995; Inkelas & Zec 1993, Peperkamp 1997; Zec 2005, Bisol 2005, entre outros). No caso do Português Brasileiro, não parece ser diferente, pois as palavras funcionais monossilábicas não formam um pé na maioria dos casos, não recebendo acento primário. Entretanto há palavras funcionais dissilábicas e até trissilábicas que preenchem essa condição e, portanto recebem acento primário. Segundo Selkirk (1995), as palavras funcionais do inglês podem ser prosodizadas como palavras prosódicas independentes em três situações: (i) pronunciadas isoladamente; (ii) em posição final de sintagma; e (iii) estão focalizadas, pois recebem pitch accent nesses casos. Para Vigário (1999), no Português Europeu, somente os complementizadores podem ser Palavras Prosódicas independentes, quando em posição final de sintagma entoacional, pois recebem a proeminência desse domínio. Nos demais casos, as palavras funcionais serão formas 'fracas', portanto, clíticos. Este trabalho propõe investigar as diferentes prosodizações das palavras funcionais (preposições, artigos, conjunções e pronomes clíticos) e o modo como são integradas à estrutura prosódica do PB, em um corpus de fala experimental, considerando a hipótese de que dependendo da posição em I e do contexto discursivo, podem ser prosodizadas como clítico, ou como Palavra Prosódica independente, formando, no caso de serem clíticos, o Grupo de Palavra Prosódica, de acordo com a proposta de Vigário (2007). Esse trabalho tem o objetivo maior de contribuir com os estudos do domínio da Palavra Prosódica no PB. / Abstract: In the language there are several elements that are difficult to organize, mainly to make reference to prosodic status, and the functional words are one of these elements, because while the lexical words are always Prosodic Word, they have already been formed in the lexical component, as they receive lexical stress the functional words show a variable standard between the language, they can show many things as clitics or prosodic words (cf. Selkirk 1984, 1995; Inkelas & Zec 1993, Peperkamp 1997; Zec 2005, Bisol 2005, between others). In the case of Brazilian Portuguese, it doesn't seem be different, because the monosyllabic words don't constitute a foot in the majority of the cases and they don't receive primary stress. However there are disyllabics functional words and trisyllabics words that fill this condition, so they receive primary stress. According to Selkirk (1995) the functional words in English can be prosodized like independent prosodic words in three situations: (i) they are pronounced isolately; (ii) they are in the ending of the phrase; and (iii) they are focalized, because they receive pitch accent in these cases. According Vigário (1999) in European Portuguese, only the complementizers can be prosodic words, when they are in the ending of the intonational phrase, because they receive a prominence of these domain. In both languages, in the other cases, the functional words will be 'weak' forms, so clitics. This paper proposes investigate the different prosodizations of the functional words (prepositions, articles, conjunctions and clitics pronouns) and the way like are integrated to the prosodic structure of BP, in particular in the spoken variety at a Campinas' s region in a corpus of experimental speech considering the hypothesis that depending of the position in intonational phrase, they can be prosodized like Clitics, or like Independent Prosodic Words. If they are clitics, they will form with the host the Minimal Prosodic Word proposed by Vigário (2007). This paper has the mayor goal to contribute with the studies to domain Prosodic Word in BP. / Mestrado / Mestre em Linguística

Neste contexto, este trabalho relata o desenvolvimento e avaliação de um sistema para segmentação automática de fala usando o algoritmo de Viterbi e refinamento das fronteiras de segmentação baseado nas características fonético-acústicas das classes fonéticas. As subunidades fonéticas (dependentes de contexto) são representadas com Modelos Ocultos de Markov (HMM - Hidden Markov Models). Cada fronteira estimada pelo algoritmo de Viterbi é refinada usando características acústicas dependentes de classes de fones, uma vez que a identidade dos fones do lado direito e esquerdo da fronteira considerada é conhecida. O sistema proposto foi avaliado usando duas bases dependentes de locutor do Português do Brasil (uma masculina e outra feminina) e também uma base independente de locutor (TIMIT). A avaliação foi realizada comparando a segmentação automática com a segmentação manual. Depois do processo de refinamento, um ganho de 29% nas fronteiras com erro de segmentação abaixo de 20 ms foi obtido para a base de fala dependente de locutor masculino do Português Brasileiro. / Abstract: The demand for reliable automatic speech segmentation is increasing and requiring additional research to support the development of systems that use speech for man-machine interface. In this context, this work reports the development and evaluation of a system for automatic speech segmentation using Viterbi's algorithm and a refinement of segmentation boundaries based on acoustic-phonetic features. Phonetic sub-units (context-dependent phones) are modeled with HMM (Hidden Markov Models). Each boundary estimated by Viterbi's algorithm is refined using class-dependent acoustic features, as the identity of the phones on the left and right side of the considered boundary is known. The proposed system was evaluated using two speaker dependent Brazilian Portuguese speech databases (one male and one female speaker), and a speaker independent English database (TIMIT). The evaluation was carried out comparing automatic against manual segmentation. After the refinement process, an improvement of 29% in the percentage of segmentation errors below 20 ms was achieved for the male speaker dependent Brazilian Portuguese speech database. / Doutorado / Telecomunicações e Telemática / Doutor em Engenharia Elétrica

The theoretical foundation is sustained on the postulates of Camara Jr. (1970 ), Mateus (1982), de Morais Barbosa (1994) and Moraes and Wetzels (1992), concerning nasality in Portuguese, especially in Brazilian Portuguese. The theoretical framework of Acoustic Phonetics is composed mainly by the work of Ladefoged (2003, 2006 and 2007), Ladefoged, Johnson (2008), Mateus et al. (2005), Delgado-Martins (1988), Morais Barbosa (1994), Malmberg (1998), Medeiros (2007), Medeiros et al. (2008) and Sousa, E. (1994). The informants used as subjects in this research, both Brazilian and Portuguese, are people with low education, low turnover, 50 years of age or older. The Brazilian informants were born and lived most of their lives in rural Fortaleza dos Nogueiras; the Portuguese live in the outskirts of Lisbon. The speech data in Brazil are a result of our field research conducted in 2011. The data from Portugal were provided by the Instituto de Linguística da Universidade de Lisboa and form part of the speech collection of ALEPG (Linguistic and Ethnographic Atlas of Portugal and Galicia). The acoustic-phonetic analysis of the data is made through the program of Speech Station by Sensimetrics for visualization of expectograms and to extract measurements of F1 and F2. We present the values of formants 1 and 2 of the oral and nasal vowels and these are compared in order to show what happens with the nasal vowel in relation to the corresponding oral; we highlight the acoustical characteristics of oral and nasal vowels; we show the articulatory triangle of vowels of the informants of the research highlighting the contours the vowels assume in articulation and the frequency bands in which each vowel stands. Finally, we carry out a comparative investigation of oral and nasal vowels in these two varieties of Portuguese. / Este trabalho apresenta uma análise fonético-acústica das vogais orais e nasais do português brasileiro, mais especificamente da comunidade de fala de Fortaleza dos Nogueiras, Maranhão e do português europeu, em alguns dados de fala da região de Lisboa, Portugal. O embasamento teórico pauta-se nos postulados de Camara Jr. (1970), de Mateus (1982), de Morais Barbosa (1994) e de Moraes e Wetzels (1992), acerca da nasalidade na língua portuguesa, especialmente, no português brasileiro. O referencial teórico de Fonética Acústica compõe-se, principalmente, pelos trabalhos de Ladefoged (2003, 2006 e 2007), Ladefoged; Jonhson (2008), Mateus et al. (2005), Delgado-Martins (1988), Morais Barbosa (1994), Malmberg (1998), Medeiros (2007), Medeiros et al. (2008) e Sousa, E. (1994). Os informantes sujeitos desta pesquisa, tanto brasileiros como portugueses, são pessoas com baixa escolaridade, baixa rotatividade, que têm a partir de 50 anos de idade. Os brasileiros nasceram e viveram a maior parte de suas vidas na zona rural de Fortaleza dos Nogueiras; os portugueses são moradores do entorno de Lisboa. Os dados de fala do Brasil são resultado de nossa pesquisa de campo realizada em 2011. Os de Portugal foram-nos cedidos pelo Instituto de Linguística da Universidade de Lisboa e fazem parte do acervo de fala do ALEPG (Atlas Linguístico e Etnográfico de Portugal e da Galiza). A análise fonético-acústica dos dados é feita por meio do programa Speech Station da Sensimetrics, para a visualização dos expectogramas e para a extração das medidas de F1 e de F2. Apresentam-se os valores dos formantes 1 e 2 das vogais orais e nasais e estes são comparados com o intuito de mostrar o que acontece com a vogal nasal em relação à correspondente oral; evidenciam-se quais as características acústicas das vogais orais e nasais; apresenta-se o triângulo articulatório das vogais desses informantes da pesquisa com evidência para os contornos que elas assumem na articulação e para as faixas de frequência em que cada vogal se posiciona. Por fim, realiza-se uma investigação comparativa das vogais orais e nasais nessas duas variedades da língua portuguesa.

Tradução grafema-fonema para a língua portuguesa baseada em autômatos adaptativos. / Grapheme-phoneme translation for portuguese based on adaptive automata.

Danilo Picagli Shibata 25 March 2008 (has links)
Este trabalho apresenta um estudo sobre a utilização de dispositivos adaptativos para realizar tradução texto-voz. O foco do trabalho é a criação de um método para a tradução grafema-fonema para a língua portuguesa baseado em autômatos adaptativos e seu uso em um software de tradução texto-voz. O método apresentado busca mimetizar o comportamento humano no tratamento de regras de tonicidade, separação de sílabas e as influências que as sílabas exercem sobre suas vizinhas. Essa característica torna o método facilmente utilizável para outras variações da língua portuguesa, considerando que essas características são invariantes em relação à localidade e a época da variedade escolhida. A variação contemporânea da língua falada na cidade de São Paulo foi escolhida como alvo de análise e testes neste trabalho. Para essa variação, o modelo apresenta resultados satisfatórios superando 95% de acerto na tradução grafema-fonema de palavras, chegando a 90% de acerto levando em consideração a resolução de dúvidas geradas por palavras que podem possuir duas representações sonoras e gerando uma saída sonora inteligível aos nativos da língua por meio da síntese por concatenação baseada em sílabas. Como resultado do trabalho, além do modelo para tradução grafema-fonema de palavras baseado em autômatos adaptativos, foi criado um método para escolha da representação fonética correta em caso de ambigüidade e foram criados dois softwares, um para simulação de autômatos adaptativos e outro para a tradução grafema-fonema de palavras utilizando o modelo de tradução criado e o método de escolha da representação correta. Esse último software foi unificado ao sintetizador desenvolvido por Koike et al. (2007) para a criação de um tradutor texto-voz para a língua portuguesa. O trabalho mostra a viabilidade da utilização de autômatos adaptativos como base ou como um elemento auxiliar para o processo de tradução texto-voz na língua portuguesa. / This work presents a study on the use of adaptive devices for text-to-speech translation. The work focuses on the development of a grapheme-phoneme translation method for Portuguese based on Adaptive Automata and the use of this method in a text-to-speech translation software. The presented method resembles human behavior when handling syllable separation rules, syllable stress definition and influences syllables have on each other. This feature makes the method easy to use with different variations of Portuguese, since these characteristics are invariants of the language. Portuguese spoken nowadays in São Paulo, Brazil has been chosen as the target for analysis and tests in this work. The method has good results for such variation of Portuguese, reaching 95% accuracy rate for grapheme-phoneme translation, clearing the 90% mark after resolution of ambiguous cases in which different representations are accepted for a grapheme and generating phonetic output intelligible for native speakers based on concatenation synthesis using syllables as concatenation units. As final results of this work, a model is presented for grapheme-phoneme translation for Portuguese words based on Adaptive Automata, a methodology to choose the correct phonetic representation for the grapheme in ambiguous cases, a software for Adaptive Automata simulation and a software for grapheme-phoneme translation of texts using both the model of translation and methodology for disambiguation. The latter software was unified with the speech synthesizer developed by Koike et al. (2007) to create a text-to-speech translator for Portuguese. This work evidences the feasibility of text-to-speech translation for Portuguese using Adaptive Automata as the main instrument for such task.

[en] THE ACQUISITION OF VERBAL MOOD IN BRAZILIAN PORTUGUESE: NATURALIST AND EXPERIMENTAL EVIDENCE OF THE PERCEPTION, EXPRESSION AND COMPREHENSION OF THE REALIS/IRREALIS MOOD DISTINCTION / [pt] O MODO VERBAL NA AQUISIÇÃO DO PORTUGUÊS BRASILEIRO: EVIDÊNCIAS NATURALISTAS E EXPERIMENTAIS DA PERCEPÇÃO, EXPRESSÃO E COMPREENSÃO DA DISTINÇÃO REALIS/IRREALIS

JACQUELINE RODRIGUES LONGCHAMPS 01 September 2009 (has links)
[pt] A presente dissertação se insere em uma teoria da aquisição da linguagem que concilia uma abordagem psicolingüística com uma concepção minimalista de língua. As hipóteses de trabalho que a nortearam foram: o que é gramaticalmente relevante tem de estar expresso na interface fônica; a interpretação semântica do complexo TAM (Tempo, Aspecto, Modo) acarreta dificuldade na identificação da morfologia de modo; distinções conceptuais fundamentais, como a oposição realis/irrealis, são expressas pela criança, independentemente de a morfologia da língua ter sido totalmente identificada (Hipótese da Oposição Semântica). Um estudo da produção espontânea de duas crianças de 1;5 a 2;5 de idade e 4 experimentos foram conduzidos. Na análise dos dados da fala espontânea, constatou-se que a oposição realis/irrealis é expressa pela criança por meio da distinção entre formas verbais flexionadas e não-flexionadas, sendo que o chamado Infinitivo Raiz (IR) aparece como alternativa ao subjuntivo para expressão do modo irrealis. Os resultados de dois experimentos de produção eliciada sugerem que a distinção indicativo/subjuntivo é percebida por crianças de 3 anos, embora aos 5 anos de idade a expressão do subjuntivo ainda apresente dificuldade. Um experimento de compreensão com perguntas SIM/NÃO com crianças de 5-7 anos, e seu follow-up, sugerem que o contraste indicativo/subjuntivo em completivas é reconhecido, ainda que respostas negativas imponham dificuldades que independem do modo, particularmente aos 5 anos. Os resultados são compatíveis com as hipóteses e sugerem que a presença do IR no português brasileiro é indicativa da alteração paramétrica em curso (de sujeito nulo para preenchido). / [en] This dissertation is in the context of a theory which reconciles a psycholinguist approach to language acquisition and a minimalist conception of language. The working hypotheses were: grammatically relevant information has to be legible at the phonetic interface; the semantic interpretation of the TAM complex (Tense, Aspect, Mood) poses difficulty to the identification of the verbal mood morphology; basic conceptual distinctions, such as the realis/irrealis contrast, are expressed by the child, no matter whether or not his/her language morphology has been totally identified (The Semantic Opposition Hypothesis). A study of the spontaneous speech production of two children, aged 1;5 to 2;5, and 4 experiments were carried out. The analysis of the production data revealed that the realis/irrealis opposition is expressed by the child by means of the distinction between inflected/uninflected verbal forms and the Root Infinitive (RI) represents an alternative form to the subjunctive for the expression of the irrealis mood. The results of two elicited production experiments suggest that the indicative/subjunctive distinction is perceived by 3-year-olds, although the expression of the subjunctive mood still poses difficulty even for 5-year-olds. A comprehension experiment involving YES/NO questions with 5-7-year-olds, and its follow-up, suggest that the indicative/subjunctive opposition in subordinate clauses is recognized, even though negative answers pose difficulties that are not related to verbal mood, particularly at 5 years of age. The results are compatible with the hypotheses, suggesting that the presence of RIs in Brazilian Portuguese indicates a parametric shift in course (from null subject to non-null subject).

Aspiration in Japanese Speakers' English : A study of the acquisition of new phonetic categories in a second language

Ekelund, Martin January 2011 (has links)
This study aims to explore if it is possible to form separate categories of aspirated voiceless stops in a second language, distinct from the equivalent categories in the native language, for native speakers of a language with an intermediate degree of aspiration, and if such category formation is eased by long-term exposure to another language in which aspirated voiceless stops exist. Two groups of adult native Japanese speakers who had lived in Sweden for a long and short time respectively were recorded when reading a list of sentences containing word-initial, utterance-medial /p t k/ in Japanese and English. Both groups produced higher VOT values for the English stops than for the Japanese stops. The results were significant for /t/ and /k/ and for the long-term residents' /p/, but not for the short-term residents' /p/, presumably because of a low number of tokens. The results are nevertheless interpreted as evident of the possibility of phonetic category formation even though there is only a small difference from the corresponding category in the native language. Since both groups had established new phonetic categories, degree of exposure to Swedish is interpreted as likely not to be a relevant factor.

ESTUDO DOS DESVIOS DE FALA EM PRÉ-ESCOLARES DE ESCOLAS PÚBLICAS ESTADUAIS DE SANTA MARIA-RS / STUDY OF SPEECH DISORDER IN CHILDREN OF PUBLIC PRE-SCHOOL IN SANTA MARIA-RS

Casarin, Maisa Tatiana 30 March 2006 (has links)
This study aimed to estimate the prevalence of speech disorder in a sample of children from a public state school, verify the prevalence of disorder in according to sex; classify the deviation according to type and severity; verify the occurrence of delay in language acquisition in children with phonological disorder; characterize the phonetic inventory and the phonological system of this sample, and verify which the most altered phonemes are. The sample was composed of 91 subjects of both sex, ranging from 5:7 and 7:5. All of them were submitted to speech-language evaluations and phonological assessments that were applied to determine the type and degree of severity of speech disorder as well as the phonetic inventory and the phonological system. For the statistical analysis Qui-Quadrado Test, Variance analysis, t-test and Kruskal-Wallis were used, with level of significance of 5% (p<0,05). Analyses were developed using SPSS 8.0 software. Amongst the 91 subjects 46 (70,3%) had speech disorder and the 27 other (29,7%) presented appropriate speech acquisition (GAFN). Considering the obtained on deviation type, the prevalence was of 18,55% for phonological deviation (GDFo), 2,10% for phonetic deviation (GDFe) and of 5,24% for phonological-phonetic deviation (GDFoFe). Association between delay in language acquisition process and the disorder type was not observed. It was noticed significant statistic association between: masculine gender and the group with speech disorder; the feminine gender and GAFN; GDFe and the tongue altered posture; GDFo and the incomplete phonetic inventory; GAFN and the complete phonetic inventory; GDFo and phonological system altered; GDFe and GAFN and the appropriate phonological system. The sounds with highest omission in the inventory were: /з /, /z/, /r/, /λ / e /g/ and /g/ for GDFo; and /r/,/g /, /z/, /∫/ and /λ / for GDFoFe. The groups GDFe and GAFN presented PCC significantly higher than GDFoFe. The phonemes with most alterations in the phonological system were: /r /, /λ/, /з /∫ / and /z/ for GDFo and /∫ /λ /, /, /r/, /g/ for GDFoFe. In both groups, the majority of subjects presented difficulties with the complex onset, and with the erasure of the rhotic consonants /r/ e /l/. As for the distinctive features it was verified that: GDFo and GDFoFe presented significant statistically altered number of features, more than GAFN; the most altered features for: [+voz] ®-voz], [-ant] ®[+ant], [+cont] ®[-cont], [-voc] ®[+voc] in GDFo and [-ant] ®[+ant], [+voz] ® [-voz], [+ant] ® [-ant] in GDFoFe. Therefore, this research shows that there is high prevalence on speech deviation/disorder in the group of preschoolers studied, and that the larger the number of missing sounds in the phonetic inventory the higher the disorder severity. Furthermore, the high number of alterations in the fricative class and the rhotic consonants suggest that the subjects who present phonological or phonological-phonetic disorders/deviations adopt similar strategies, however not identical to the ones used by children with appropriate phonological development because these classes of phonemes are, according to literature, the last to be acquired. / Este estudo teve por objetivos estimar a prevalência de desvio de fala em uma amostra de pré-escolares de escolas públicas, verificar a prevalência do desvio quanto ao sexo, classificar os desvios quanto ao tipo e à severidade, verificar se em crianças com desvios fonológicos há presença de atraso na aquisição da linguagem, caracterizar o inventário fonético e o sistema fonológico e verificar quais os fonemas mais alterados. A amostra foi formada por 91 sujeitos, de ambos os sexos, com idades entre 5:7 e 7:5. Todos foram submetidos às avaliações fonoaudiológicas e fonológica, realizadas para determinar o tipo e o grau de severidade do desvio de fala, bem como o inventário fonético e o sistema fonológico. Para análise estatística, foram utilizados o Teste Qui-quadrado, a análise de variância, o teste Kruskal-Wallis e o teste t, com nível de significância de 5% (p<0,05). Os dados foram submetidos ao software SPSS 8.0. Dos 91 sujeitos, 46 (70,3%) apresentaram fala com desvio, e os outros 27 (29,7%) apresentaram aquisição de fala normalizada (GAFN). Ao considerar os resultados obtidos por tipo de desvio, a prevalência foi de 18,55% para os desvios fonológicos (GDFo), 2,10% para o desvio fonético (GDFe) e 5,24% para o desvio fonológico-fonético (GDFoFe). Não foi constatada associação entre atraso no processo de aquisição da linguagem e tipo de desvio. Verificou-se associação estatisticamente significativa entre o sexo masculino e o grupo com desvio de fala, o sexo feminino e GAFN, o GDFe e a postura alterada de língua, o GDFo e inventário fonético incompleto, o GAFN e o inventário fonético completo, o GDFo e sistema fonológico alterado e os GDFe e GAFN e o sistema fonológico adequado. Os sons com maior número de omissões no inventário fonético foram: /з /, /z/, /r/, /λ / e /g/ no GDFo, e /r/, /g/, /z/, / ∫ / e / λ / no GDFoFe. Os grupos GDFe e GAFN apresentaram PCC significativamente maior que o do GDFoFe. Os fonemas com mais alterações no sistema fonológico foram: /r/, /λ /, /з / ∫ / e /z/ no GDFo, e / ∫ /, /λ /, /r/, /g/ no GDFoFe. Em ambos os grupos, a maioria dos sujeitos apresentou dificuldades com o onset complexo, com apagamento das líquidas /r/ e /l/. Quanto aos traços distintivos, foi verificado que os GDFo e o GDFoFe apresentaram número de traços alterados estatisticamente significativo e maior que o GAFN e que os traços mais alterados foram [+voz] ®[-voz], [-ant] ®[+ant], [+cont] ®[-cont], [-voc] ®[+voc], no GDFo, e [-ant] ®[+ant], [+voz] ®[-voz], [+ant] ®[-ant], no GDFoFe. Conclui-se, dessa forma, que há alta prevalência de desvios de fala em pré-escolares na população estudada, e quanto maior o número de sons ausentes no inventário fonético, maior pode ser a severidade do desvio. Além disso; o maior número de alterações na classe das fricativas e líquidas sugere que os sujeitos com desvios fonológico ou fonológico-fonético utilizam estratégias semelhantes, embora não idênticas, às das crianças com desenvolvimento fonológico adequado, pois essas classes de fonemas são, de acordo com a literatura consultada, as últimas a serem adquiridas.

Využití jazykových her ve výuce češtiny jako cizího jazyka pro děti / Use of Language Games in Teaching Czech as Foreign Language to Children

Kaprasová, Karolína January 2015 (has links)
The thesis deals with an analysis of language game repertory found in textbooks of foreign languages - Czech, English and German - for children of primary school age, and with a research of the use of language games in classes, which is conducted by means of a questionnaire survey. The first part contains a description of the issue of a game as such, its importance for ontogenetic and personality development of each individual based on specialized literature. The attention here is also concentrated on the existing game typologies and on defining appropriate classification according to which the game activities found in the selected textbooks will be sorted. The game activities are, in the second part, classified by belonging to the individual types of the selected classification and they are supplemented with a more detailed description in terms of language levels (phonetic, lexical and grammatical) and linguistic elements which can be practised through these activities. The questionnaire survey analysed in the third part of the thesis monitors if and to what extent teachers of foreign languages use game activities in their classes with regard to their usefulness and efficiency. Keywords: didactic game, language game, textbooks of foreign languages, phonetic level, lexical level, grammatical level

Les Irakiens déplacés sont ceux qui sont arrivés au quartier d' Al-'aCz:amîyah, depuis les années quatre-vingt jusqu’ à nos jours. L'étude propose d’élucider la relation qui lie les variables sociolinguistiques au comportement linguistique des intervenants, objet de notre étude, en choisissant trois variables phonologiques et une variable syntaxique, en fonction des trois variables sociales du sexe, de l'âge et de l'éducation. L'échantillon de l'étude comprend 113 informateurs. Ces informateurs sont considérés comme étant un échantillon représentatif des Irakiens déplacés et des habitants d'origine d’Al-'aCz:amîyah. La méthode d'analyse quantitative est utilisée pour examiner et interpréter les données collectées. Le logiciel SPSS, Progiciel de statistique pour les sciences sociales, a été utilisé pour nous aider à traiter les données et évaluer l'importance de cette variation linguistique. La présente étude est structurée en quatre chapitres. Le premier chapitre est consacré à discuter le contexte sociolinguistique. La méthodologie de cette étude est abordée dans le deuxième chapitre où nous présentons les démarches suivies dans notre étude. Dans le chapitre trois et quatre, nous essayons de décrire comment les caractéristiques linguistiques de l’arabe dialectal des Irakiens déplacés se chevauchent et subissent des interactions avec les caractéristiques de l’arabe dialectal d’Al-'aCz:amîyah, et comment ces dialectes subissent des influences réciproques dans une période donnée. Ainsi, pour pouvoir comparer les deux populations celle de d’Al-'aCz:amîyah et celle des Irakiens déplacés, nous les séparons en deux chapitres. Dans le troisième chapitre, les résultats statistiques qui sont affichés et interprétés montrent les changements phonétiques et syntaxiques intervenus dans le parler arabe des habitants originaires, et dans le quatrième chapitre, les résultats affichent les changements phonétiques et syntaxiques intervenus dans le parler arabe des habitants déplacés. / This study reveals the sociolinguistic effect of Al-'aCz:amîyah dialect on Iraqi displaced’s dialect in the phonological and syntactic level of language. Iraqis displaced are those who have come to d' Al-'aCz:amîyah neighborhood since the 1980s to the present day. The study shows the relationship which links the sociolinguistic variables to the linguistic behavior by choosing four phonological variables and one syntactic variable as far as the three social variables of sex, age and education are concerned. The sample of the study includes 113 informants. These informants are considered the representative sample of the Iraqis displaced and the original inhabitants of d'Al-'aCz:amîyah. The quantitative analysis method is employed to analyze and interpret the data collected. The SPSS (StatisticalPackage for the Social Sciences) software can be used to help us process the data and assess the significance of this linguistic variation. The present study is structured in four chapters: the first is devoted to discuss the sociolinguistic context. The methodology of this study was discussed in the second chapter where we present our own way that we use in our study. In chapter three and four , we try to describe how the linguistic features of the Arabic dialect of displacedIraqis overlap and undergo interactions with the features of the Arabic dialect of Al-'aCz:amîyah, how these dialects undergo reciprocal influences within a specified time limit. So to compare the two population that of Al-'aCz:amîyah and that of the Iraqis displaced, we divid them into two chapters: in the first, statistical results that are displayed and interpreted show the phonetic and syntactic changes in local dialect of the original inhabitants. While in the second chapter, these results indicate the phonic and the syntactic changes in the local dialect of the Iraqis displaced

L’analyse factorielle pour la modélisation acoustique des systèmes de reconnaissance de la parole / Factor analysis for acoustic modeling of speech recognition systems

Dans cette thèse, nous proposons d’utiliser des techniques fondées sur l’analyse factorielle pour la modélisation acoustique pour le traitement automatique de la parole, notamment pour la Reconnaissance Automatique de la parole. Nous nous sommes, dans un premier temps, intéressés à la réduction de l’empreinte mémoire des modèles acoustiques. Notre méthode à base d’analyse factorielle a démontré une capacité de mutualisation des paramètres des modèles acoustiques, tout en maintenant des performances similaires à celles des modèles de base. La modélisation proposée nous conduit à décomposer l’ensemble des paramètres des modèles acoustiques en sous-ensembles de paramètres indépendants, ce qui permet une grande flexibilité pour d’éventuelles adaptations (locuteurs, genre, nouvelles tâches).Dans les modélisations actuelles, un état d’un Modèle de Markov Caché (MMC) est représenté par un mélange de Gaussiennes (GMM : Gaussian Mixture Model). Nous proposons, comme alternative, une représentation vectorielle des états : les fac- teur d’états. Ces facteur d’états nous permettent de mesurer efficacement la similarité entre les états des MMC au moyen d’une distance euclidienne, par exemple. Grâce à cette représenation vectorielle, nous proposons une méthode simple et efficace pour la construction de modèles acoustiques avec des états partagés. Cette procédure s’avère encore plus efficace dans le cas de langues peu ou très peu dotées en ressouces et enconnaissances linguistiques. Enfin, nos efforts se sont portés sur la robustesse des systèmes de reconnaissance de la parole face aux variabilités acoustiques, et plus particulièrement celles générées par l’environnement. Nous nous sommes intéressés, dans nos différentes expérimentations, à la variabilité locuteur, à la variabilité canal et au bruit additif. Grâce à notre approche s’appuyant sur l’analyse factorielle, nous avons démontré la possibilité de modéliser ces différents types de variabilité acoustique nuisible comme une composante additive dans le domaine cepstral. Nous soustrayons cette composante des vecteurs cepstraux pour annuler son effet pénalisant pour la reconnaissance de la parole / In this thesis, we propose to use techniques based on factor analysis to build acoustic models for automatic speech processing, especially Automatic Speech Recognition (ASR). Frstly, we were interested in reducing the footprint memory of acoustic models. Our factor analysis-based method demonstrated that it is possible to pool the parameters of acoustic models and still maintain performance similar to the one obtained with the baseline models. The proposed modeling leads us to deconstruct the ensemble of the acoustic model parameters into independent parameter sub-sets, which allow a great flexibility for particular adaptations (speakers, genre, new tasks etc.). With current modeling techniques, the state of a Hidden Markov Model (HMM) is represented by a combination of Gaussians (GMM : Gaussian Mixture Model). We propose as an alternative a vector representation of states : the factors of states. These factors of states enable us to accurately measure the similarity between the states of the HMM by means of an euclidean distance for example. Using this vector represen- tation, we propose a simple and effective method for building acoustic models with shared states. This procedure is even more effective when applied to under-resourced languages. Finally, we concentrated our efforts on the robustness of the speech recognition sys- tems to acoustic variabilities, particularly those generated by the environment. In our various experiments, we examined speaker variability, channel variability and additive noise. Through our factor analysis-based approach, we demonstrated the possibility of modeling these different types of acoustic variability as an additive component in the cepstral domain. By compensation of this component from the cepstral vectors, we are able to cancel out the harmful effect it has on speech recognition
