Purpose: To investigate the immediate effect of voiced tongue vibration (VSL), high-resistance straw in the air (CAR), and overarticulation (OA) on the vocal space of vocally healthy women (MVS) and with vocal nodules (MNV).
Methods: 12 women participated in the MNV and 12 women in the MVS, allocated to perform the vocal exercises of VSL, CAR, and OA. Each participant performed only one of the three proposed exercises, for 5 minutes, preceded and followed by recording a sequence of vehicle sentences for extracting formants (F1 and F2) from the vowel segments [a, i, u].
Aim: To analyze the accuracy of traditional acoustic measurements (F0, perturbation, and noise) and formant measurements in discriminating between women with and without voice disorders, and with different laryngeal disorders.
Study Design: A descriptive, cross-sectional, and retrospective.
Method: Two hundred and sixty women participated.
Purpose: To analyze the acoustic-articulatory configuration of vowels in women with vocal nodules and with healthy voice.
Methods: Twelve women with vocal nodules (EG) and twelve vocally health women (CG) participated of this study. All women recorded vehicle phrases with the vowels /a/, /i/, and /u/ in stress position, preceded and followed by the occlusive consonant /p/: "Digo papa baixinho", "Digo pipa baixinho", and "Digo pupa baixinho".
Purpose: Investigate the accuracy of isolated and combined acoustic measurements in the discrimination of voice deviation intensity (GD) and predominant voice quality (PVQ) in patients with dysphonia.
Methods: A total of 302 female patients with voice complaints participated in the study. The sustained /ɛ/ vowel was used to extract the following acoustic measures: mean and standard deviation (SD) of fundamental frequency (F0), jitter, shimmer, glottal to noise excitation (GNE) ratio and the mean of the first three formants (F1, F2, and F3).
