Abstract

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". Subsequently, the first three formants (F1, F2, and F3) were extracted from these vowel targets.

RESULTS: Between the two groups studied, F1 measures differed for vowels /a/ and /u/, and F2 measures differed for the vowel /a/. Women with vocal nodules showed lower values for these measures compared to vocally healthy women. Patients with vocal nodules showed a smaller interval in F1 and F2 values between vowels /a/, /i/, and /u/ compared to vocally healthy women.

CONCLUSION: Women with vocal nodules show lower F1 and F2 values and lower range of motion of the articulators during vowel production compared to vocally healthy women.
