“…Voice assessment is a quantitative way to evaluate voices, which is of great significance in evaluating voice quality, verifying the diagnosis of voice disorders and assessing the prognosis of therapy. [1][2] Generally, voice assessment refers to the acoustic analysis, aerodynamic analysis and formant analysis. Due to the COVID-19 pandemic, people in many voice centers tend to wear medical masks when their voices are being evaluated.…”

Objective. Voice assessment is of great significance to the evaluation of voice quality. Our study aims to explore the effects of medical masks on healthy people in acoustic, aerodynamic and formant parameters during the COVID-19 pandemic. In addition, we also attempted to verify the differences between different sexes and ages. Methods. Fifty-three healthy participants (25 males and 28 females) were involved in our study. The acoustic parameters, including fundamental frequency (F0), sound pressure level (SPL), percentage of jitter (%), percentage of shimmer (%), noise to harmonic ratio (NHR) and cepstral peak prominence (CPP), aerodynamic parameter (maximum phonation time, MPT) and formant parameters (formant frequency, F1, F2, F3) without and with wearing medical masks were included. We further investigated the potential differences in the impact on different sexes and ages (≤45 years old and >45 years old). Results. While wearing medical masks, the SPL significantly increased (71.22 §4.25 dB, 72.42 §3.96 dB, P = 0.021). Jitter and shimmer significantly decreased (jitter 1.19 §0.83, 0.87 §0.67 P = 0.005; shimmer 4.49 § 2.20, 3.66 §2.02 P = 0.002), as did F3 (2855 §323.34 Hz, 2781.89 §353.42 Hz P = 0.004). F0, MPT, F1 and F2 showed increasing trends without statistical significance, and NHR as well as CPP showed little change without and with wearing medical masks. There were no significant differences seen between males and females. Regarding to age, a significant difference in MPT was seen (>45-year-old 16.15 §6.98 s, 15.38 §7.02 s; ≤45-year-old 20.26 §6.47 s, 21.44 §6.98 s, P = 0.032). Conclusion. Healthy participants showed a significantly higher SPL, a smaller perturbation and an evident decrease in F3 after wearing medical masks. These changes may result from the adjustment of the vocal tract and the filtration function of medical masks, leading to the stability of voices we recorded being overstated. The impacts of medical masks on sex were not evident, while the MPT in the >45-year-old group was influenced more than that in the ≤45-year-old group.

“…A speech-language-hearing therapist with more than 10 years of experience in the area conducted the auditory-perceptual analysis of the voices to describe and characterize the overall severity of the samples (7,19) . He was instructed to consider a sample with normal variability of voice quality, produced with no irregularities, noises, or observable effects during vowel emission.…”

“…Even though it is a subjective analysis, it is pointed out as the main method to assess voice disorders (4,5) . Hence, the effort to find an objective voice assessment led to progress in voice analysis, helping to understand the relationship between physiology (input) and auditory acoustic sound signal (voice output) (6,7) .…”

“…The acoustic analysis provides visual and normative data on the glottal source and voice filter (6,8) . Some acoustic measures furnish quantitative data on the glottal source -e.g., the fundamental frequency (f0), defined by the number of vibrations per second produced by the vocal folds; jitter, the short-term variation in the fundamental frequency; shimmer, which indicates the shortterm amplitude variability of the wave sound; glottal-to-noise excitation (GNE), which verifies the additional noise in the voice signal; and cepstral peak prominence-smoothed (CPPS), which determines the f0 and estimates the aperiodicity and/or additional noise in the voice signal (4,5,7) .…”

“…The literature has demonstrated that voice disorders may manifest in various ways in the glottal source and filter (vocal tract), due to the constant interaction between the respiratory, phonatory, and resonant subsystems (7,8,10,11) . Thus, knowing investigative measures regarding the vocal tract can indicate new paths in voice diagnosis and rehabilitation.…”

Purpose To compare the acoustic and auditory-perceptual measures of the voice of women with and without vocal nodules. Methods Twelve women with vocal nodules (MNV group) and 12 without vocal nodules (MSNV group) participated in the study. They were submitted to the recording of their sustained /a/ vowel, in order to extract the mean of the fundamental frequency (f0), standard deviation of f0 (SD f0), jitter, shimmer, GNE, cepstral measure of CPPS, and spectral measures of differences of the first and second harmonics (H1-H2); and recording of the carrier phrases: “I say papa baixinho”, “I say pipa baixinho” and “I say pupa baixinho”, to extract the first (F1) and second formant (F2) of the vowel segments /a, i, u/. For auditory-perceptual assessment, the visual-analog scale (VAS) was used. Results The comparative analysis between the groups shows higher values for the MNV in the parameters general degree, roughness and breathiness, and for the shimmer acoustic measure. The F1 values for the vowels /a/ and /u/, and the F2 values for the vowel /a/ were higher in the same group. Conclusion According to the data observed in the investigated sample, women with nodules have more deviated voices, with the presence of roughness and breathiness, and changes in vocal tract adjustments, with a possible reduction in the amplitude of the articulators, when compared to women without vocal nodules.

RESUMO Objetivo Comparar as medidas acústicas e perceptivo-auditivas de mulheres com e sem nódulos vocais. Métodos Participaram do estudo 12 mulheres com nódulos vocais (grupo MNV) e 12 sem nódulos vocais (grupo MSNV). Foram submetidas à gravação da vogal /a/ sustentada, com o objetivo de extrair a média da frequência fundamental (f0), desvio padrão de f0 (DP f0), jitter, shimmer, Glottal Noise Excitation, medidas relacionadas ao Cepstral Peak Prominence-Smoothed, medidas espectrais das diferenças do primeiro e segundo harmônico (H1-H2) e gravação das frases-veículo: “Digo papa baixinho”, “Digo pipa baixinho” e “Digo pupa baixinho”, para extração do primeiro (F1) e segundo formante (F2) dos segmentos vocálicos /a, i, u/. Para avaliação perceptivo-auditiva, utilizou-se a Escala Visual Analógica. Resultados A análise comparativa entre os grupos evidenciou maiores valores para o grupo MNV nos parâmetros grau geral, rugosidade e soprosidade e para a medida acústica shimmer. Os valores de F1 para as vogais /a/ e /u/ e os valores de F2 para a vogal /a/ apresentaram-se mais elevados no mesmo grupo. Conclusão mulheres com nódulos apresentaram vozes mais desviadas, com presença de rugosidade e soprosidade e modificações nos ajustes do trato vocal, com possível redução na amplitude dos articuladores, quando comparadas às mulheres sem nódulos vocais.
