چکیده
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. Twentyfour 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 MultiDimensional 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.

Conflict of interest: non-existent requires of the motor information of the pathways for articulation and sensory information. Sensory information is obtained through auditory feedback, which also interferes with the correction and improvement of muscle control of the organs involved in vocal production3. Due to the lack of kinesthetic feedback presented by these children, the vowels tend to be...
