De modo especial, o GG é fortemente correlacionado ao CPPS. O declínio espectral apresentou correlação positiva moderada com o GT e correlação negativa fraca com o GS.Ĭonclusão: Existe associação entre a presença de desvio vocal, o GG, a qualidade vocal predominante e o CPPS. O CPPS se correlacionou de modo positivo e forte com os GG e GS, de modo negativo moderado com o GR, e de forma negativa fraca com o GT. O declínio espectral apenas diferenciou vozes soprosas x tensas. Os valores do CPPS diferenciaram vozes rugosas x soprosas, rugosas x tensas e soprosas x tensas. Os valores do CPPS foram mais reduzidos em função da presença e intensidade do desvio vocal. Resultados: Houve diferença dos valores do CPPS entre os grupos com e sem desvio vocal, assim como entre as diferentes intensidades e tipos de desvio vocal. Foram extraídas as medidas relacionadas ao Cepstral Peak Prominence-Smoothed (CPPS) e o declínio espectral das amostras vocais. Utilizou-se uma escala analógico-visual para análise perceptivo-auditiva das vozes quanto à intensidade do desvio vocal (GG), graus de rugosidade (GR), soprosidade (GS) e tensão (GT), incluindo-se a determinação da qualidade vocal predominante (rugosa, soprosa ou tensa). Método: Foram utilizadas 376 amostras da vogal /ε/ de indivíduos de ambos os gêneros, com queixa vocal. Objetivo: Analisar se existe associação entre a presença, a intensidade e o tipo de desvio vocal e as medidas cepstrais em amostras de indivíduos com queixa vocal. Spectral decline is associated only with the parameters B and S. In particular, G is strongly correlated with CPPS. The spectral decline had a moderate positive correlation with S and a weak negative correlation with B.Ĭonclusion: There is association between voice disorder, G, predominant voice quality, and CPPS. CPPS correlated positively and strongly with G and B moderately and negatively with R, and negatively and weakly with S. The spectral decline only differentiated breathy x strained voices. The CPPS values differentiated the following voices: rough x breathy, rough x strained, and breathy x strained. CPPS values were lower because of the presence and intensity of voice disorders. Results: There were differences in the CPPS values between the groups with or without voice disorders as well as between the different intensities and types of voice disorder. Measures related to cepstral peak prominence smoothed (CPPS) and spectral decline of vocal samples were extracted. An analogue-visual scale was used for the auditory-perceptual analysis of voices regarding the overall grade of dysphonia (G) and the grades of roughness (R), breathiness (B), and strain (S), including a determination of voice quality (rough, breathy or strained). Methods: We used 376 vowel /Ɛ/ samples from individuals of both genders that had voice complaints. Purpose: To analyze whether there is an association between the presence, intensity and type of voice disorder and the cepstral measures in samples of individuals with voice complaints.
