RECONHECIMENTO DE SENTENÇAS COM DIFERENTES VELOCIDADES DE FALA EM IDOSOS / SENTENCES RECOGNITION WITH DIFFERENT SPEECH SPEEDS IN OLDER PEOPLE

Lessa, Alexandre Hundertmarck 01 March 2012 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / PURPOSE: to propose a version of the Portuguese Sentences Lists test with slowed speech speed; to verify the naturalness, clarity and applicability of the new material; to evaluate the change in the recognition performance in adults and elderly with the variation of the speech s speed; to verify hearing loss and speed of the verbal stimulus presentation variables on the speech recognition in the elderly. METHODS: was realized elongation of 25% compared to the original duration of the Portuguese Sentences Lists test. Adults and elderly normalhearing did a perceptual analysis of the produced material. After this, the adults had obtained their Slowed Sentences Recognition Thresholds in Quiet, Slowed Sentences Recognition Indices in Quiet and Sentences Recognition Indices in Quiet. The data were subjected to statistical analysis. Both normal-hearing elderly, than elderly people with hearing loss were subjected to these same evaluations, and have also been submitted to obtain their Sentences Recognition Indices in Noise, Slowed Sentences Recognition Indices in Noise. The data were statistically analyzed and compared. RESULTS: the modified material was recorded on Compact Disc. After its presentation to adults and elderly normal-hearing, which performed the perceptual analysis of the test, it was considered clear and natural. The evaluations, through the Portuguese Sentences Lists and Portuguese Slowed Sentences Lists tests, showed that an improvement was observed with the presentation of the slowed stimuli in relation to the presentation at typical speed in the group of adults to the measurements obtained in silence, but without statistical significance. As for as the groups of elderly normal-hearing and older people with hearing loss, was also observed an improvement in slowed sentences recognition, but with a statistically significant difference. Regarding the noise assessments carried out with the elderly, was obtained statistically significant improvement in the presentation of the sentences at a slowed speed in the group with hearing loss, but not in the elderly normal-hearing one. CONCLUSION: the modified material, named Portuguese Slowed Sentences Lists test, proved applicability and sensibility to investigate the temporal aspects influence in speech recognition in the older people. The elderly demonstrated more ease to understand the spoken message, when it was presented with slowed speed. The findings of this research shows that the elderly, independent of the peripheral hearing, have best benefit on the speech recognition, when the heard message is slower in the silence. Considering the speech in noise, have been shown evidence that older adults with hearing loss had more benefit when the speech is slowed than those with normal hearing. / OBJETIVOS: propor uma versão do teste Listas de Sentenças em Português com menor velocidade de fala; verificar a naturalidade, clareza e aplicabilidade do novo material desenvolvido; aplicar ambos os testes em sujeitos adultos e idosos e avaliar a mudança no desempenho de reconhecimento da fala destes com a variação da velocidade de apresentação do estímulo verbal; verificar as variáveis perda auditiva e velocidade de apresentação do estímulo verbal no reconhecimento de fala em idosos. MATERIAL E MÉTODO: neste estudo, foi realizada elongação de 25% em relação à duração original das frases do teste Listas de Sentenças em Português. Adultos e idosos normo-ouvintes fizeram uma análise perceptivo-auditiva do material produzido. Após, o grupo de adultos teve seus Limiares de Reconhecimento de Sentenças Lentificadas no Silêncio, Índices Percentuais de Reconhecimento de Sentenças Lentificadas no Silêncio e Índices Percentuais de Reconhecimento de Sentenças no Silêncio obtidos. Tanto idosos normo-ouvintes, quanto idosos com perda auditiva foram submetidos a estas mesmas avaliações, além de terem sido submetidos também à obtenção dos Limiares de Reconhecimento de Sentenças Lentificadas no Ruído, Índices Percentuais de Reconhecimento de Sentenças Lentificadas no Ruído e Índices Percentuais de Reconhecimento de Sentenças no Ruído. Os dados obtidos foram submetidos à análise estatística e comparados. RESULTADOS: o material modificado foi gravado em Compact Disc. Após sua apresentação a indivíduos adultos e idosos normo-ouvintes, que realizaram análise perceptivo-auditiva do teste, este foi considerado claro e natural. As avaliações realizadas, através dos testes Listas de Sentenças em Português e Listas de Sentenças Lentificadas em Português, demonstraram que foi verificada melhora de desempenho com a apresentação dos estímulos em velocidade diminuída, em relação à apresentação em velocidade típica no grupo de adultos para as medidas obtidas no silêncio, porém sem significância estatística. Já para os grupos de idosos normo-ouvintes e de idosos com perda auditiva, também verificou-se melhora com o reconhecimento de sentenças em velocidade diminuída, porém com diferença estatisticamente significante. Em relação às avaliações no Ruído, realizadas com os idosos, obteve-se melhora estatisticamente significante à apresentação das sentenças em velocidade diminuída no grupo com perda auditiva, mas não no de idosos normo-ouvintes. CONCLUSÕES: o material modificado, nomeado Listas de Sentenças Lentificadas em Português, mostrou-se aplicável e sensível para investigar a influência de aspectos temporais no reconhecimento da fala em idosos. Os achados da presente pesquisa evidenciam que os idosos, independente da audição periférica, se beneficiam no que concerne ao reconhecimento da mensagem ouvida, quando a fala é realizada em velocidade mais lenta no silêncio. Quanto à fala no ruído, foram mostrados indícios de que idosos com perda auditiva se beneficiaram mais do que aqueles com normalidade auditiva, quando a velocidade da fala é diminuída.

Dimenze přívětivosti ve vnímání osobnosti mluvčího podle melodie řeči / Speech melody in perception of speaker's agreeableness

Bartůňková, Hana January 2014 (has links)
Tato práce hledá souvislost mezi intonačním rozpětím a přívětivostí, která je podle Pětifaktorového modelu považována za jednu ze složek osobnosti. Jelikož zkoumání projevů osobnostních rysů v hlase není ve fonetickém výzkumu příliš běžné, je v teoretické části popsán sou- časný stav poznání v oblasti postojů, popisu osobnosti a prvních do- jmů v hodnocení osobnosti. Představeny jsou především studie, které se týkají působení řeči. Jádrem práce je experiment, v němž je porov- náván vliv tří úrovní intonačního rozpětí (komprimovaná, normální a expandovaná) na hodnocení přívětivosti u 15 českých mluvčí. Per- cepčního testu se účastnilo 41 respondentů Intonačnímu rozpětí je věnována samostatná kapitola, která se zaměřuje především na pro- blematická místa popisu. Statistická analýza neprokázala významné rozdíly mezi úrovněmi rozpětí, podrobnější rozbor se tak zaměřil na odhalení rušivých proměnných a popis slabších trendů. Klíčová slova: intonační rozpětí, melodie řeči, vnímání mluvčího, stereo- typní hodnocení Abstract The purpose of the current study is to establish the relationship be- tween pitch range and agreeableness which is viewed as one of the personality traits according to the Big Five model. As the focus on the manifestation of personality traits in speech is not very common in phonetic...

Výslovnostní redukce na úrovni slov ve spontánní řeči a identifikovatelnost řečových jednotek / Word-level pronunciation reduction in spotaneous speech and identification of speech units

Tomanová, Eliška January 2012 (has links)
The thesis deals with the issue of word-level pronunciation reductions and with the identification of reduced word forms. The first part of the thesis focuses on the degree of the phonetic features' stability and presents an analysis of selected words from dialogues with a high degree of spontaneity. The results of this research confirm that the most stable features of speech are the fricativness of sibilants and / /ř , voice, the formant structure of vowels and the nasality of the nasal consonant. The closure of the explosives and the quality of vowels prove, on the other hand, to be relatively unstable features. The second part of the thesis focuses on perceptual tests, which are used to verify the identifiability of the selected words in relation to the degree of reduction and the type and complexity of the context. Furthemore, the thesis tries to determine the phonetic features, which are under given conditions relevant for the appropriate identification of words. The research proved, that the most often noted phonetic features correspond to the above mentioned features with high stability. Moreover, it was also confirmed, that the recognizability of words depends on the degree of their reduction and the type of the context: strongly reduced words without any context tend to be very difficult...

Avaliação do desempenho dos deficientes auditivos na percepção de fala, utilizando aparelho de amplificação sonora individual, com o algoritmo de redução de ruído - Speech Sensitive Processing / Performance of hearing impaired people using a hearing aid with a noise supression algorithms

Oliveira, Jerusa Roberta Massola de 28 June 2002 (has links)
Objetivo: O objetivo deste estudo foi avaliar clinicamente o desempenho dos indivíduos adultos com deficiência auditiva neurossensorial, com relação à percepção da fala, utilizando o aparelho de amplificação sonora individual digital Prisma, da empresa Siemens, com o algoritmo de redução de ruído denominado Speech Sensitive Processing (SSP), ativado e desativado na presença de um ruído competitivo. Material e Método: Este estudo foi realizado no CEDALVI, no período de 1998 a 2000, em 32 indivíduos com deficiência auditiva neurossensorial de graus leve, moderado ou leve a moderado, de ambos os sexos. Foi realizada a avaliação dos indivíduos por meio de um teste de percepção de fala, onde se pesquisou o reconhecimento de sentenças na presença de um ruído, para obter a relação sinal/ruído (S/R) dos indivíduos, utilizando o AASI digital Prisma. Descrição dos resultados: Neste estudo, o algoritmo SSP pôde proporcionar benefício para a maioria dos indivíduos deficientes auditivos, na pesquisa da relação S/R e os resultados apontaram diferença estatisticamente significante (p=0,0021) na condição em que o SSP encontrava-se ativado, em comparação à condição em que o SSP não se encontrava ativado. Conclusão: Com os resultados, pode-se afirmar que o uso clínico do algoritmo de redução de ruído SSP deve ser pensado como outra alternativa clínica, pois observamos a eficácia desse sistema na redução do ruído, melhorando a percepção da fala. / Objective: It was the aim of this study to assess the performance of adult individuals with a neurosensorial hearing loss, related to speech perception, using a Prisma digital individual sound amplification appliance, made by Siemmens Enterprise, with the algorithm of sound reduction called Speech Sensitive Processing (SSP), activated and non activated, in the presence of a competing noise. Material and Method: This study was performed at CEDALVI, during the period from 1998 to 2000, with 32 both sexes individuals with a neurosensorial hearing loss of light, moderate or light to moderate grade. An assessment has been made of the individuals through a speech perception test, where the recognition of sentences in the presence of a noise was investigated, in order to get a signal/noise rate (S/R), using Prisma Digital AASI. Result Description: In this study, SSP algorithm could afford a benefit for most hearing impaired individuals, in the investigation of S/R rate and the results pointed to a statistically significant difference(p=0.0021) in the condition of activated SSP, compared to the condition where SSP was not activated. Conclusion: Based on results one may state that clinical use of sound reduction algorithm. SSP must be considered as another clinical alternative, as we observed the efficacy of noise reduction, increasing speech perception.
