Resumo: Esta dissertação apresenta um estudo intercultural da percepção de emoções expressas pela fala em situações comunicativas reais conduzido com ouvintes brasileiros e suecos. A literatura sobre o tema mostra que sujeitos ouvintes são capazes de reconhecer emoções expressas na fala em experimentos de percepção com um percentual de sucesso muito superior ao que seria obtido ao acaso, mesmo quando avaliando estímulos em uma língua estrangeira e de uma cultura diferente. Os principais objetivos do estudo apresentado foram investigar quais parâmetros fonético-acústicos dentre os extraídos são afetados pelo estado emocional dos falantes, em quais deles os sujeitos ouvintes se guiam para julgar o grau de expressão dessas emoções nos experimentos de percepção, investigar se os sujeitos realizam melhor essa tarefa para dimensões emocionais do que para emoções discretas, se a cultura e a língua materna dos sujeitos influenciam na percepção das emoções e se os sujeitos brasileiros e suecos se guiam pelos mesmos parâmetros acústicos para fazer esse julgamento. Os corpora utilizados consistem de enunciados de mulheres falantes do português brasileiro e do sueco extraídos de um documentário e de programas de televisão e de rádio. Os enunciados passaram por uma análise acústica, na qual as seguintes classes de parâmetros acústicos foram medidas automaticamente com um script para o programa PRAAT: frequência fundamental e sua primeira derivada, intensidade global, inclinação espectral e espectro médio de longo-termo (LTAS). Dessas classes foram calculados vários descritores estatísticos, totalizando doze parâmetros acústicos. Conduzimos dois experimentos de percepção com sujeitos brasileiros e suecos. No primeiro deles, os sujeitos avaliaram, em escalas graduadas de 0 a 4, o grau de expressão de emoções discretas descritas por oito adjetivos (alegre, comovido, surpreso, triste, contente, angustiado, aflito e entusiasmado) para os enunciados em português brasileiro. No segundo experimento, os sujeitos julgaram o grau de expressão de cinco dimensões emocionais (ativação, justiça, valência, motivação e envolvimento) para os enunciados em sueco. As respostas dos sujeitos nos experimentos foram submetidas a análises de PCA. Para o experimento I, essas análises revelaram que as emoções descritas pelos oito adjetivos foram avaliadas pelos sujeitos de ambas as nacionalidades conjuntamente por duas grandes dimensões emocionais: felicidade e neutralidade. Para o experimento II, os dois componentes da PCA revelaram que os sujeitos de ambas as nacionalidades julgaram as cinco dimensões emocionais distinguindo entre um estado de "calma" de um estado de maior agitação emocional. Os componentes da PCA foram correlacionados com os parâmetros acústicos por meio de análises de regressões lineares, que mostraram que os sujeitos de ambas as nacionalidades se guiaram pelos mesmos parâmetros acústicos para realizar os julgamentos nos dois experimentos. Esses parâmetros também foram muito robustos em classificar os trechos de fala nas análises de LDA realizadas. Os parâmetros que se mostraram mais relevantes foram o LTAS, a mediana e a semiamplitude entre quartis da frequência fundamental e a média e o desvio-padrão da inclinação espectral. É possível concluir que a cultura e a experiência emocional dos sujeitos brasileiros e suecos não influenciaram na percepção das emoções expressas nos dois corpora
Abstract: This dissertation presents a cross-cultural study on the perception of real emotions expressed in speech conducted with Swedish and Brazilian listeners. The literature on the subject shows that listeners are capable of recognizing emotions expressed in speech in perception experiments with much higher percentage of success than that expected by chance, even when evaluating stimuli in a foreign language and of a different culture. The main objectives of the present study were to investigate which acoustic-phonetic parameters among those extracted are affected by the emotional state of the speakers, on which of them the listeners rely to judge the degree of expression of these emotions in the perception experiments, to investigate whether the subjects perform better in this task when evaluating emotional dimensions rather than discrete emotions, whether the listeners¿ culture and mother language affect the perception of the emotions and whether the Brazilian and the Swedish subjects rely on the same acoustic parameters to make the judgements. The corpora used consist of utterances of female speakers of Brazilian Portuguese and Swedish extracted from a documentary film as well as from radio and TV programs. The following acoustic parameters were measured automatically for these utterances with a script for the software PRAAT: fundamental frequency and its first derivative, global intensity, spectral tilt and Long-Term Average Spectrum (LTAS). A total of twelve statistical descriptors were computed for these parameters. We conducted two perception experiments with Brazilian and Swedish subjects. In the first one they evaluated the degree of expression of the discrete emotions described by eight adjectives (joyful, moved, surprised, sad, contented, anguished, distressed and enthusiastic) for the utterances in Brazilian Portuguese on scales ranging from 0 to 4. In the second experiment the subjects rated the degree of expression of five emotional dimensions (activation, fairness, valence, motivation and involvement) for the utterances in Swedish. The responses of the subjects in the experiments were analyzed by means of PCA. For experiment I, the PCA revealed that the listeners of both nationalities evaluated the emotions described by the eight adjectives jointly by means of two major emotional dimensions: happiness and neutrality. For experiment II, the two PCA components revealed that the listeners of both nationalities evaluated the five emotional dimensions distinguishing between a state of "calmness" and a state of higher emotional agitation. The PCA components were correlated with the acoustic parameters by means of linear regression analyses. These analyses showed that the subjects of both nationalities relied on the same acoustic parameters to make the judgements in both experiments. These acoustic parameters were also very robust in classifying the utterances in the LDA performed. The parameters which proved more relevant were the LTAS, fundamental frequency median and semi-interquartile range and spectral tilt mean and standard deviation. It is possible to conclude that the culture and the emotional experience of the Brazilian and the Swedish subjects did not affect the perception of the emotions expressed in both corpora

Повний текст джерелаThe background for this project is a wish to automate synchronization of text and speech. The idea is to present speech through speakers synchronized word-for-word with text appearing on a monitor.
The solution decided upon is to use artificial neural networks, ANNs, to convert both text and speech into streams made up of sets of phonetic features and then matching these two streams against each other. Several text-to-feature ANN designs based on the NETtalk system are implemented and evaluated. The extraction of phonetic features from speech and the synchronization itself are not implemented, but some assessments are made regarding their possible performances. The performance of a finished system is not possible to determine, but a NETtalk-based ANN is believed to be suitable for such a system using phonetic features for synchronization.

Повний текст джерелаO desenvolvimento fonológico típico e o desvio fonológico são alvos de incessantes estudos na área da Fonoaudiologia, no sentido de buscar a caracterização de aspectos como aquisição de fonemas, estratégias de reparo presentes na produção dos sujeitos, características articulatórias e acústicas dos sons. Neste último aspecto, torna-se importante, também, a comparação entre os dados obtidos na fala das crianças com dados de fala adulta, no sentido de verificar se os parâmetros acústicos se assemelham. Assim, o objetivo deste trabalho foi comparar, com auxílio da análise acústica, as produções de [s] e [ʃ] de crianças com desenvolvimento fonológico típico e com desvio fonológico e de adultos, considerando os parâmetros acústicos de duração do ruído fricativo, frequência de corte do ruído fricativo, banda de frequências de maior concentração de ruído fricativo e transição formântica da vogal seguinte aos fones estudados. Foram realizadas comparações entre os dados de fala de 31 sujeitos, divididos em três grupos grupo de crianças com desenvolvimento fonológico típico (com idade média de 7,12 anos, ± 0,77), grupo de crianças com desvio fonológico (com idade média de 6,87 anos, ± 0,74) e grupo de adultos (com idade média de 23,61 anos, ± 3,445). Os sujeitos advinham de escolas da cidade de Santa Maria/RS e do Serviço de Atendimento Fonoaudiológico da Universidade Federal de Santa Maria e realizaram entrevista inicial, triagem e avaliação fonológica. Os dados de fala a serem analisados foram coletados em cabine tratada acusticamente e para a realização da análise acústica foram utilizados dois softwares: Praat e Wavesurfer. Para análise estatística dos dados foram realizadas comparações entre o grupo de crianças com desenvolvimento fonológico típico e o grupo de adultos e entre crianças com desenvolvimento fonológico típico e com desvio fonológico. Verificou-se que, quando considerados alguns parâmetros acústicos, como duração do ruído fricativo e frequência de corte do ruído fricativo, as produções das crianças com desenvolvimento fonológico típico são estatisticamente iguais às produções dos adultos. Por vezes, as produções desses grupos apresentam-se diferentes acusticamente, mas não perceptivo-auditivamente, o que pode ser justificado pelo processo neuromaturacional que as crianças estão passando na idade pesquisada. Ainda, observou-se que as crianças com desvio fonológico apresentavam realmente substituições envolvendo os fones estudados. Um exemplo sobre este fato é o caso do [s] fruto de uma substituição (quando o alvo era o fonema /ʃ/) apresentar as mesmas características acústicas que um [s] corretamente produzido, isto é, que representa fonema /s/. Os parâmetros que se mostraram os mais eficientes na diferenciação dos fones [s] e [ʃ] foram frequência de corte do ruído fricativo e banda de frequências de concentração do ruído fricativo, para adultos e crianças com desenvolvimento fonológico típico.

Повний текст джерелаThe first part of this thesis is devoted to the analysis of disordered connected speech. The aim is to investigate vocal cues that are clinically relevant and correlated with auditory-perceptual ratings. Two approaches are investigated. The variogram-based method in the temporal domain is addressed first. The second approach is in the cepstral domain. In particular, the first rahmonic amplitude is used as an acoustic cue to describe voice quality. A multi-dimensional approach combining temporal and spectral aspects is also investigated. The goal is to check whether acoustic cues in both domains report complementary information when predicting perceptual scores.
Both methods are tested first on a corpus of synthetic sound stimuli that has been obtained by means of a synthesizer of disordered voices. The purpose is to learn about the link between the signal properties (fixed by the synthesis parameters) and acoustic cues.
In this study, we had the opportunity to use two large natural speech corpora. One of them has been perceptually rated.
The final part of the text is devoted to the automatic classification of voice with regard to perceived voice quality. Many studies have proposed a binary (normal/pathological) classification of voice samples. An automatic categorization according to perceived degrees of hoarseness appears, however, to be more attractive to both clinicians and technologists and more likely to be clinically relevant. Indeed, one way to reduce inter-rater variability of an auditory-perceptual evaluation is to ask several experts to participate and then to average the perceptual scores. However, auditory-perceptual evaluation of a corpus by several judges is a very laborious, time-consuming and costly task. Making this perceptual evaluation task automatic is therefore desirable.
The aim of this study is to exploit the support vector machine classifier that has become, over the last years, a popular tool for classification, to carry out categorization of voices according to perceived degrees of hoarseness.

Повний текст джерелаENGLISH ABSTRACT: This thesis presents a system that is designed to replace the manual process of generating a pronunciation dictionary for use in automatic speech recognition. The proposed system has several stages. The first stage segments the audio into what will be known as the subword units, using a frequency domain method. In the second stage, dynamic time warping is used to determine the similarity between the segments of each possible pair of these acoustic segments. These similarities are used to cluster similar acoustic segments into acoustic clusters. The final stage derives a pronunciation dictionary from the orthography of the training data and corresponding sequence of acoustic clusters. This process begins with an initial mapping between words and their sequence of clusters, established by Viterbi alignment with the orthographic transcription. The dictionary is refined iteratively by pruning redundant mappings, hidden Markov model estimation and Viterbi re-alignment in each iteration. This approach is evaluated experimentally by applying it to two subsets of the TIMIT corpus. It is found that, when test words are repeated often in the training material, the approach leads to a system whose accuracy is almost as good as one trained using the phonetic transcriptions. When test words are not repeated often in the training set, the proposed approach leads to better results than those achieved using the phonetic transcriptions, although the recognition is poor overall in this case.
AFRIKAANSE OPSOMMING: Die doelwit van die tesis is om ’n stelsel te beskryf wat ontwerp is om die handgedrewe proses in die samestelling van ’n woordeboek, vir die gebruik in outomatiese spraakherkenningsstelsels, te vervang. Die voorgestelde stelsel bestaan uit ’n aantal stappe. Die eerste stap is die segmentering van die oudio in sogenaamde sub-woord eenhede deur gebruik te maak van ’n frekwensie gebied tegniek. Met die tweede stap word die dinamiese tydverplasingsalgoritme ingespan om die ooreenkoms tussen die segmente van elkeen van die moontlike pare van die akoestiese segmente bepaal. Die ooreenkomste word dan gebruik om die akoestiese segmente te groepeer in akoestiese groepe. Die laaste stap stel die woordeboek saam deur gebruik te maak van die ortografiese transkripsie van afrigtingsdata en die ooreenstemmende reeks akoestiese groepe. Die finale stap begin met ’n aanvanklike afbeelding vanaf woorde tot hul reeks groep identifiseerders, bewerkstellig deur Viterbi belyning en die ortografiese transkripsie. Die woordeboek word iteratief verfyn deur oortollige afbeeldings te snoei, verskuilde Markov modelle af te rig en deur Viterbi belyning te gebruik in elke iterasie. Die benadering is getoets deur dit eksperimenteel te evalueer op twee subversamelings data vanuit die TIMIT korpus. Daar is bevind dat, wanneer woorde herhaal word in die afrigtingsdata, die stelsel se benadering die akkuraatheid ewenaar van ’n stelsel wat met die fonetiese transkripsie afgerig is. As die woorde nie herhaal word in die afrigtingsdata nie, is die akkuraatheid van die stelsel se benadering beter as wanneer die stelsel afgerig word met die fonetiese transkripsie, alhoewel die akkuraatheid in die algemeen swak is.

Objective: to investigate implementation strategies for phonic voicing contrast in Brazilian Portuguese in a study group of children with speech alteration in comparison to a control group of children without alteration. Methods: we selected six subjects ranging from 7-10 years old, three with diagnosis of alterations in the production of voicing contrast in speech and three as controls. Six carrier sentences with target disyllabic words in a CVCV structure, containing voice and voiceless pairs of plosive consonants in Brazilian Portuguese in contexts of tonic and post-tonic syllables, were audio recorded (five random repetitions). The collected samples were acoustically investigated, labeled and submitted to procedures to extract caustic measures of fundamental frequency (f0) in the beginning and in the stationary point of the vowel following the plosive consonant, frequency of first formant (F1) in the beginning and in the stationary point of the vowel following the plosive consonant and duration measures of: plosive consonant, vowel preceding the the plosive consonant, vowel following the plosive consonant, voice-onset-time (VOT) in the plosive consonant, voicing period, voiceless period, voicing redemption, total pre-plosion and plosion times. We also measured the VCV excerpt of the target word to calculate relative duration. Speech samples were then submitted to a perception experiment for auditive judgment (vocable identification) by a group of 35 judges. Acoustic measure results were submitted to sample comparison test, hierarchical cluster analysis and discriminate analysis. Tasks in the auditive judgment were presented by means of confusion matrices and calculation of auditive distances. Correspondence data between acoustic and perceptive findings were submitted to logistics regression analysis. The research project was approved by the Research Ethics Committee (119/09). Results: acoustic measures were compared between voiceless and voiced plosive consonant pairs and, in general, showed significant differences. However, voiceless and voiced plosive consonants were grouped differently in the different contexts in each group studied and also showed predictive capacity to identify control and study groups. With regard to perception, auditive distances showed to be smaller for the study group samples in comparison to the control group in the tonic context. In the post-tonic context, auditive differences were similar between the two groups. Consonant duration, from voiceless and total pre-plosion periods (tonic context) and total pre-plosion duration and voicing period (post-tonic context) showed predictive power in the auditive judgment of voicing contrast in speech alterations of voiced plosive consonants. For voiceless plosive consonants, influent measures included f0 in the beginning of the vowel and duration of previous vowel (tonic context) and f0 in the beginning of the vowel and duration of plosive consonant (post-tonic context). Conclusion: investigation of implementations found in children s speech signal showed that duration measures were influent in identifying speech with voicing contrast alterations, signaling traces of implementation of more than one action to analyze voicing contrast
Objetivo: investigar as estratégias de implementação do contraste fônico de vozeamento no português brasileiro em um grupo de crianças com alteração da fala em comparação a um grupo de crianças sem alteração. Métodos: foram selecionados seis sujeitos, na faixa etária de 7-10 anos, sendo três com diagnóstico fonoaudiológico de alteração na produção do contraste de vozeamento na fala e três atuando como referência. Seis sentenças-veículo com palavras-alvo, dissílabas com estrutura CVCV, contendo os pares vozeados e não vozeados das consoantes plosivas do português brasileiro, em contextos de sílaba tônica e pós-tônica, foram audiogravadas (cinco repetições aleatorizadas). As amostras coletadas foram inspecionadas acusticamente, etiquetadas e submetidas a procedimentos de extração das medidas acústicas de frequência fundamental (f0) no início e no ponto estacionário da vogal seguinte à consoante plosiva, frequência do primeiro formante (F1) no início e no ponto estacionário da vogal seguinte à consoante plosiva e medidas de duração de consoante plosiva, vogal anterior à consoante plosiva, vogal seguinte à consoante plosiva, voice-onset-time (VOT) na consoante plosiva, período de vozeamento, período sem vozeamento, retomada do vozeamento, total préplosão e plosão e medida do trecho VCV da palavra-alvo, para finalidade de cálculo da duração relativa. Na sequência, as amostras de fala foram submetidas a experimento de percepção para julgamento auditivo (identificação de vocábulos) por um grupo de 35 juízes. Os resultados das medidas acústicas foram submetidos a teste de comparação de amostras, análise hierárquica de cluster e análise discriminante. As respostas do julgamento auditivo foram apresentadas por meio de matrizes de confusão e de cálculo das distâncias auditivas. Os dados de correspondências entre achados acústicos e perceptivos foram submetidos à análise de regressão logística. O projeto da pesquisa foi aprovado pelo Comitê de Ética em Pesquisa (119/09). Resultados: as medidas acústicas foram comparadas entre os pares de consoantes plosivas não vozeadas e vozeadas e, no geral, revelaram diferenças significativas. Contudo, agruparam-se diferentemente para as consoantes plosivas não vozeadas e vozeadas para cada grupo estudado nos distintos contextos, e ainda apresentaram capacidade preditiva em classificar os grupos com alteração e referência. Em termos de percepção, as distâncias auditivas apresentaram-se menores para as amostras do grupo com alteração em comparação com o grupo referência no contexto tônico. Para o contexto pós-tônico, as distâncias auditivas foram similares entre os dois grupos. A duração da consoante, do período sem vozeamento e do total pré-plosão (contexto tônico) e a duração do total pré-plosão e o período de vozeamento (contexto pós-tônico) revelaram poder preditivo do julgamento auditivo do contraste de vozeamento de fala alterada para as consoantes plosivas vozeadas. Para as consoantes plosivas não vozeadas as medidas influentes foram f0 no início da vogal e duração da vogal anterior (contexto tônico) e f0 no início da vogal e duração da consoante plosiva (contexto pós-tônico). Conclusão: a investigação das implementações encontradas no sinal de fala das crianças revelou que as medidas de duração foram influentes na identificação da fala com contraste de vozeamento alterado, sinalizando os indícios de implementação de mais de uma ação para a análise do contraste de vozeamento

To characterize the supraglottic vocal tract shaping in the production of the seven oral and five nasal vowels of brazilian portuguese from the articulatory point of view by means of magnetic resonance imaging (MRI). Methods: The subject of this study, one female native speaker of brazilian portuguese, had no previous alterations of speech, language or of neurological and auditory systems and with neither dental nor articulator alterations. The magnetic resonance images, collected during the production of the vowels sustained by the speaker, were analyzed for articulatory characterization. The results were considered according to articulatory and acoustic data researched in the related literature. Results and discussion: The nasal vowels, unlike the oral ones, presented three different moments, which are characterized by changes in the position of the articulators during their production; while the oral vowels presented only one moment/phase. The oral vowels, when compared to the nasal, maintained similar characteristics, being articulatorily classified by the position of their tongue-surface (both vertically and horizontally), by the opening of the oral cavity, by the rounding of the lips and by the position of the soft palate. The vowels that presented the greater differences, when compared to their oral and nasal counterparts, were [a]-[ã], [o]-[õ] and [u]-[uâ]. Production of nasal vowels took a longer time than their oral counterparts yielding a larger number of frames captured. Conclusion: Data obtained by means of MRI has allowed the analysis of the movements of the articulators during the production of the vowels contributing to: increasing the knowledge of brazilian portuguese vowels production mechanisms; characterizing the brazilian portuguese vowels inventory; providing insights to the evaluation and rehabilitation of speech disorders
Caracterizar a configuração do trato vocal supraglótico na produção das sete vogais orais e cinco nasais do português brasileiro do ponto de vista articulatório por meio de imagens de ressonância magnética (IRM). Métodos: Atuou como sujeito da pesquisa, um falante do gênero feminino nativo do português brasileiro, com histórico negativo para alterações de fala, linguagem e dos sistemas neurológico e auditivo e ausência de alterações dentárias e de articuladores. As imagens de ressonância magnética, coletadas durante a produção das vogais sustentadas pelo falante, foram analisadas para caracterização articulatória. Os resultados foram considerados em relação aos dados articulatórios e acústicos pesquisados na literatura. Resultados e discussão: As vogais nasais, ao contrário das orais, apresentaram três momentos distintos, caracterizados por mudanças no posicionamento dos articuladores durante sua emissão; enquanto que as vogais orais apresentaram apenas um momento/fase. As vogais orais, quando comparadas com as nasais, mantiveram características semelhantes, sendo classificadas articulatoriamente pelo posicionamento do dorso de língua (no sentido vertical e horizontal), pela abertura da cavidade oral, pelo arredondamento labial e pelo posicionamento do palato mole. As vogais que apresentaram maior modificação, quando comparadas entre suas correspondentes oral e nasal, foram [a]-[ã], [o]-[õ] e [u]-[uâ].
