【 摘 要 】

BACKGROUND: effectiveness of the sonorous tongue vibration technique (STVT). AIM: to investigate the sensations and the vocal and laryngeal impact produced by the sonorous tongue vibration technique. METHOD: The STVT was performed in three sets of fifteen repetitions, in maximum phonatory duration using a normal tone and intensity - with 30 seconds intervals of passive rest between each set. Twenty-four women aged between 20 and 30 years and with no vocal complaints participated in the study. All participants were submitted to a larynx evaluation through videolaryngostroboscopy examination; auditory perceptual and acoustic analysis of the voice, before and after using the STVT, by means of the Multi-Dimensional Voice Program (MDVP), Model 5105 and Real Time Spectrogram, from Key Elemetrics.RESULTS: after using the STVT, a statistically significant difference was observed in terms of: improvement of voice type; focus of vertical resonance; vocal quality; predominance of positive sensations; maintenance of the larynx images parameters (glottis closure, laryngeal vestibule constriction, symmetry and amplitude of vocal folds vibration); increase in fundamental frequency; improvement of spectrographic evaluation parameters, in Broadband and Narrowband filters; and improvement of medial vestibule constriction according to increase in STVT duration. CONCLUSION: the STVT modifies the glottal source and the resonant filter.
