Resumo: | AIM: to verify whether the phonetic nature script Vocal Profile Analysis Scheme can be applied to Brazilian Portuguese (VPAS-BP) or not, for the perceptive evaluation of quality and vocal dynamics of speech samples in a group of teachers with vocal disturbs and laryngeal changes from two public schools in Sorocaba city (SP), as well as to discuss the correspondence with acoustic analysis data. METHODOLOGY: The above mentioned group was formed by 25 female teachers with complaints or voice disturbs and medical diagnosis of laryngeal changes. The stimuli used for the auditoryperceptive analysis refer to records of semi-spontaneous speech (interview and class simulation) and to reading standard texts, totalizing 75 stimuli taken from data banks of previous researches. Those samples were selected on the basis of perceptive experiments (nature and duration of samples) and values in the relationship signal/noise. After the experiments, the samples were edited and analyzed by means of acoustic and perceptive procedures. From the auditory-perceptive point of view, the samples were evaluated by 5 judges; from those, 4 participated in a 15 hour workshop on how to use the VPAS-BP. The 90 samples (75 plus 15 repetitions) were randomly presented through the script Experiment MFC 3.2, applied to the software PRAAT (version 5143). From the acoustic point of view, the same samples were edited through the script SG Expression Evaluator, and it was possible to extract f0, intensity, spectral slope and the long term spectrum (LTS).The perceptive and acoustic data were statistically analyzed: comparison of the average and analysis of multiple correlations (canonic analysis, cluster analysis and discriminant). Features like the agreement and trustfulness inter and intra judges in the VPAS-BP were treated by means of the Cochran and Snedecor test to analyze the behavior of the judges group. It was also made the analysis of the vocal quality profile in the studied samples, the agglomerative cluster hierarchical analysis, the vocal qualities adjustments and vocal dynamics aspects. The acoustic data were analyzed through the agglomerative cluster hierarchical analysis. The procedures of canonical correlation and discriminant analysis were applied to the study of the correlations among perceptive data and acoustic measures. RESULTS: the most frequent adjustments of vocal quality in the studied group were, in decreasing order: laryngeal hyperfunction, harsh voice, lifted larynx, vocal tract hyperfunction, closed jaw, pharynx constriction, lifted tongue body and air escape. The features of vocal dynamics, in decreasing order, were: inadequate breathing support, less variety in pitch, lifted usual pitch, lifted usual loudness, fast elocution rate and raised variety in loudness. The acoustic measures that showed extreme combinations were: mean and absolute deviation of spectral slope and ELT absolute deviation, in one extreme, and in the other, f0 median and quantile of 99,5%. Concerning the correspondence between the perceptive and acoustic data, it was found that the f0 measures (median) and ETL measures (absolute deviation) were close to phonatory adjustments. In one hand, the f0 measures (asymmetry and semi amplitude between quarts) and the intensity (asymmetry) were in the same group of lifted larynx adjustments, less extension of jaw and less variety of loudness, whereas the f0 measures (99,5% quantile) and the spectral slope measures (media, absolute deviation and asymmetry) were in a group with the biggest concentration of adjustments. The most frequent were: laryngeal hyperfunction, closed jaw and lifted tongue body, as well as the dynamic vocal aspects related to inadequate breathing support, lifted usual pitch and loudness, less variety of pitch and loudness. CONCLUSIONS: it was verified that the VPAS-BP was totally applicable to the group of teachers in this study, for the findings of vocal quality and vocal dynamics were compatible with the voice disturbs and laryngeal changes (physiological level) and with the acoustic measures, according to the inclusion criteria in the samples |

MÉTODOS: A casuística refere-se a 25 professores do sexo feminino com queixas ou manifestações de distúrbio de voz e diagnóstico otorrinolaringológico de alteração laríngea. Os estímulos utilizados para a análise perceptivo-auditiva referem-se a gravações de trechos de fala semiespontânea (entrevista e simulação de aula) e de leitura de texto padronizado, totalizando 75 estímulos retirados de banco de dados de pesquisa anterior. Tais amostras foram selecionadas com base em experimentos de percepção (natureza e duração das amostras) e valores da relação sinal-ruído. Após os experimentos, as amostras foram editadas e analisadas por meio de procedimentos acústico e perceptivo. Do ponto de vista perceptivo-auditivo, as amostras foram avaliadas por cinco juízes, dos quais quatro participaram de Workshop de 15 horas no uso do roteiro VPAS-PB. As 90 amostras (75, somadas 15 repetições) foram apresentadas aleatoriamente por meio de script Experiment MFC 3.2 aplicável ao software PRAAT (versão 5143). Do ponto de vista acústico, as mesmas amostras foram analisadas por meio do script SG Expression Evaluator, propiciando a extração de medidas de frequência fundamental (f0), intensidade, declínio espectral e espectro de longo termo (ELT). Os dados perceptivos e acústicos foram analisados estatisticamente: comparação de médias e análises de correlações múltiplas (análise canônica, de cluster, e discriminante). Aspectos como a concordância e a confiabilidade inter e intrajuízes no roteiro VPASPB foram tratados por meio dos testes de Cochran e Snedecor para análise do comportamento do grupo de juízes. Também foi realizada a análise do perfil da qualidade vocal das amostras estudadas, além da análise aglomerativa hierárquica de cluster, dos ajustes de qualidade vocal e aspectos de dinâmica vocal. Os dados acústicos foram analisados por meio da análise aglomerativa hierárquica de cluster. Os procedimentos de análise de correlação canônica e de análise discriminante foram aplicados ao estudo das correlações entre dados perceptivos e medidas acústicas. RESULTADOS: Os ajustes de qualidade vocal mais frequentes no grupo estudado, em ordem decrescente de ocorrência foram: hiperfunção laríngea, voz áspera, laringe elevada, hiperfunção do trato vocal, mandíbula fechada, constrição faríngea, corpo de língua elevado e escape de ar. Quanto aos aspectos da dinâmica vocal, em ordem decrescente, destacaram-se: suporte respiratório inadequado, diminuição da variabilidade de pitch, pitch habitual elevado, loudness habitual elevado, taxa de elocução rápida e variabilidade de loudness aumentado. As medidas acústicas que mostraram combinações extremas foram: média e desvio-padrão de declínio espectral e desvio-padrão de ELT, num extremo, e no outro, mediana de f0 e quantil de 99,5% de f0. Com relação à correspondência entre os dados perceptivos e os acústicos foi encontrado que as medidas de f0 (mediana) e de ELT (desvio-padrão) estiveram próximas a ajustes fonatórios. De um lado, as medidas de f0 (assimetria e semiamplitude entre quartis), bem como a intensidade (assimetria), estiveram em grupo com ajustes de laringe elevada, extensão diminuída de mandíbula e variabilidade diminuída de loudness. De outro lado, as medidas de f0 (quantil 99,5%) e de declínio espectral (média, desvio-padrão e assimetria) estiveram localizadas em grupo com a maior concentração de ajustes, dentre os quais, dos mais frequentes, destacaram-se hiperfunção laríngea, hiperfunção de trato vocal, constrição faríngea, mandíbula fechada e corpo de língua elevado, além dos aspectos de dinâmica vocal relativos a suporte respiratório inadequado, pitch e loudness habitual elevados, pitch e loudness variabilidade diminuída. CONCLUSÕES: O roteiro de avaliação de qualidade vocal de base fonética VPAS-PB mostrou-se justamente aplicável ao grupo de professores do presente estudo uma vez que os achados de qualidade vocal e de dinâmica vocal apresentaram-se compatíveis com os quadros de distúrbio de voz e alteração laríngea (plano fisiológico) e com as medidas acústicas, conforme critérios de inclusão na amostraCoordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfhttp://tede2.pucsp.br/tede/retrieve/30208/Maria%20Fabiana%20Bonfim%20de%20Lima%20Silva.pdf.jpgporPontifícia Universidade Católica de São PauloPrograma de Estudos Pós-Graduados em Linguística Aplicada e Estudos da LinguagemPUC-SPBRLingüísticaQualidade de vozPercepção auditivaAcústica da falaMedida de produção da falaFonéticaVoice qualityAuditory perceptionSpeech acousticsSpeech production measurePhoneticsCNPQ::LINGUISTICA, LETRAS E ARTES::LINGUISTICA::LINGUISTICA APLICADAAvaliação de qualidade vocal com motivação fonética: análise integrada de dados de percepção e acústicaVocal quality evaluation with phonetical motivation: integrated analisys of perception and acoustic datainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da PUC_SPinstname:Pontifícia Universidade Católica de São Paulo (PUC-SP)instacron:PUC_SPTEXTMaria Fabiana Bonfim de Lima Silva.pdf.txtMaria Fabiana Bonfim de Lima Silva.pdf.txtExtracted texttext/plain281714https://repositorio.pucsp.br/xmlui/bitstream/handle/13573/3/Maria%20Fabiana%20Bonfim%20de%20Lima%20Silva.pdf.txt0889c6eb144fcde0ead894d883dd7878MD53ORIGINALMaria Fabiana Bonfim de Lima Silva.pdfapplication/pdf10169308https://repositorio.pucsp.br/xmlui/bitstream/handle/13573/1/Maria%20Fabiana%20Bonfim%20de%20Lima%20Silva.pdf0cc84e0e17f2254fc5039a44b84c1664MD51THUMBNAILMaria Fabiana Bonfim de Lima Silva.pdf.jpgMaria Fabiana Bonfim de Lima Silva.pdf.jpgGenerated Thumbnailimage/jpeg1943https://repositorio.pucsp.br/xmlui/bitstream/handle/13573/2/Maria%20Fabiana%20Bonfim%20de%20Lima%20Silva.pdf.jpgcc73c4c239a4c332d642ba1e7c7a9fb2MD52handle/135732023-06-26 11:28:59.237oai:repositorio.pucsp.br:handle/13573Biblioteca Digital de Teses e Dissertaçõeshttps://sapientia.pucsp.br/https://sapientia.pucsp.br/oai/requestbngkatende@pucsp.br||rapassi@pucsp.bropendoar:2023-06-26T14:28:59Biblioteca Digital de Teses e Dissertações da PUC_SP - Pontifícia Universidade Católica de São Paulo (PUC-SP)false |
