Methods: the corpus consisted of speech samples (sentences contained in the instructional material of the Vocal Profile Analysis Scheme - VPAS-PB) from seven adult subjects of both genders, recorded simultaneously by acoustic and ultrasonographic means. Data analysis was based on auditory-perceptual judgments of vocal quality and ultrasound images generated by the AAA software. Results: vocal quality settings related to the position of the tongue body and the extension of the tongue and jaw found correspondences to the contours of ultrasound images of the tongue in selected key segments (oral vowels), especially those with greater degrees of manifestation. Conclusion: there were correspondences between vocal quality settings detected in the perceptual sphere and their respective tongue body and jaw ultrasound images.

Com o objetivo de verificar a contribuicao da EGG, em associacao ao instrumental acustico, escolheu-se o contraste fonico de vozeamento, em situacao de fala sem alteracao, para ser investigado. Participaram do estudo tres falantes do portugues brasileiro. As amostras analisadas contemplaram gravacao simultânea dos sinais acustico e eletroglotografico com pares de consoantes plosivas nao vozeadas e vozeadas. Este estudo indicou ser a EGG uma tecnica eficiente para analisar e caracterizar a fala, no que se refere ao contraste fonico de vozeamento em situacao de fala sem alteracao.

Methods: the studied populationwas made up by six total laryngectomized individuals between 40 and 60-year old, of both genders,esophageal or tracheae-esophageal speech speakers. Life and Voice Quality (QVV) protocol (Behlauet al., 2001) and a fluency scale guide (Robe et al. ,1956) were applied for trials of Speech Therapygraduation and post-graduation students; and voice self-perception guide for trials of total laryngectomizedindividuals. Results: the values for Physical Dominion of QVV were on average 63.19 and in the Social-Emotional Dominion 80.20, considering 100 as threshold. The subjects that showed a low global scoreare those that feel a major voice discomfort, referred to as tension and hoarseness and that theexaminers classified as subjects with limitations to communicate. The subjects with v...

The adaptation of the VPAS into Brazilian Portuguese was accomplished and the corpus to be used in the training of judges was built up. Furthermore, the voice quality database necessary for the application of the protocol was recorded, evaluated by two expertise subjects and integrated into the instructive material of the PB-VPAS. Preliminary data from six judges (linguists and speech therapists) who attended a PB-VPAS workshop using the material described (in 2 stages: before and after a 20-hour workshop on VPAS) are presented. The relevance of the application of PB-VPAS to the analysis of voice disorders and expressiveness uses of voice quality is pointed out.

The corpus was perceptually annotated by the VPAS and data from 44 speakers were grouped in terms of the most frequent combinations in the VPAS system, generating two vocal profiles; the “Wide” and the “Short” vocal tract kinds of profiles. Acoustic measures (f0, intensity, signal to noise ratio, spectral slope and the first formant) were extracted. Statistical analysis weighs the relative links between the voice quality profiles and the acoustic measures, compared to linguistic and gender constraints. f0 measures were found to be the most relevant to establish perceptual and acoustic correlations. Some singularities of the cor...

The corpus was composed of speech samples from 43 children, ranging from six (06) to fourteen (14) years old. Speech acoustic measures and clinical evaluation of lingual frenulum data were statistically analyzed by means of regression analysis in order to investigate the validity of each acoustic parameter to predict lingual frenulum disorders. The results reinforce the relevance to establish voice quality correspondences to lingual frenulum disorders, since evidences of dysphonia were detected.

O objetivo foi caracterizar, do ponto de vista fisiologico (eletroglotografico), a degluticao em diferentes tarefas (degluticao de liquido, saliva, saliva com esforco e na pausa de fala) em 40 individuos adultos falantes do portugues brasileiro. As exploracoes da onda Gx e medidas dGx indicam a movimentacao laringea diferenciada por tarefas, no momento da degluticao. Valores de referencia sao sugeridos para as quatro tarefas estudadas e podem ser futuramente aplicados a clinica fonoaudiologica. ABSTRACT: Pause analysis may help bring further understanding about speech dynamics and how it relates to correlate functions, such as swallowing and breathing. The objective of this study was to characterize swallowing physiologically, with the use of electroglottography, in different tasks (swallowing liquid, saliva, saliva with effort, and ...

The possibility of taking into account the interface between speech perception and production may be productive when analyzing data collected from clinical settings or developing researches in which the central questions arose from the clinical practice. The dynamics aspects of speech are considered. The series of studies reported reinforces the indication of a highly integrated and cooperative approach among the several research areas concerned on speech production and perception. The capability of producing speech under disorders caused by damages in phonatory and auditory systems can stimulate researchers to develop approaches that could influence theoretical models, rehabilitation tools and speech technologies development.

Metodos: 14 juizes foram selecionados e participaram de um curso de 20 horas de duracao em analise fonetica da qualidade vocal, no qual analisaram os registros de voz de dois falantes por meio do VPAS – etapa 1 (identificacao de presenca/ausencia de ajustes). Seus julgamentos foram comparados aos de dois examinadores experientes no roteiro (adotados como referencia), a partir dos quais foi composto um grupo de sete (7) examinadores para a etapa 2 (graduacao dos ajustes presentes em escala de 1 a 6). Os juizes participantes da etapa 2 tambem responderam a um questionario. Os dados foram analisados quanto a comparacao dos julgamentos e respostas ao questionario dos juizes do grupo estudado. Resultados: os resultados foram apresentados e discutidos em relacao a fundamentacao e aplicabilidade do roteiro, apontando, em ordem decrescent...

Methods: the studied was represented by voice samples taken form from 20 dysphonic people aged between 30 and 65 of the female gender (attended in a hospital in the city of Sao Paulo) and the auditory perception judgment of the vocal quality was represented by samples previously evaluated by active judges in clinic activity. The samples were explored as for the frequency of the fi rst three formants (F1, F2 and F3). The values were considered as for their quality (compared to the data of auditory perception analysis) and their quantity (Qui-square test) Results: the more frequent adjustments of vocal quality were low larynx, closed jaw, lip rounding, lowered tongue body, retracted tongue body, labiodentalization. Statistically meaningful differences were found for the fre...

Foi realizado um estudo fonetico-acustico de producoes de fala de um locutor masculino, natural e residente do municipio de Sao Jose do Rio Preto. A analise dos padroes entoacionais indicou semelhanca com outras pesquisas em relacao a diferenciacao entre enunciados declarativos e interrogativos, sendo o contorno de frequencia fundamental (F0) a caracteristica acustica que melhor representa essa diferenciacao. Diferencas de alinhamento do pico de F0 na vogal tonica da palavra final dos enunciados tambem foram encontradas e correlacionadas com efeitos de sentido assertivos e inquisitivos.
