RECONHECIMENTO DE SENTENÇAS COM DIFERENTES VELOCIDADES DE FALA EM IDOSOS / SENTENCES RECOGNITION WITH DIFFERENT SPEECH SPEEDS IN OLDER PEOPLELessa, 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 agreeablenessBartůňková, 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 unitsTomanová, 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 algorithmsOliveira, 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.
