PURPOSE: to check the immediate effect of vocal techniques: vibration, nasal sound and overarticulation. METHOD: 32 female subjects with normal to mild dysphonia took part in the study, with ages from 20 to 45 years. Subjects were submitted to perceptual analysis and laryngostroboscopic exams before and after the use of vocal techniques. RESULTS: subjects' vocal classification in perceptual analysis after accomplishing the vocal techniques showed significant improvement on parameters voice global impression, hoarseness and stability; and, in spontaneous speech, one showed a significant improvement on the parameter articulation. The acoustic analysis evidenced significant improvement of the jitter and shimmer. Laryngostroboscopic examination evidenced a significant increase in the glottic closing and an increase in the mucondulatory movement of the vocal folds. The results found in perceptual evaluation are compatible with some studies in the literature on the effect concerning the application of vocal techniques. However, laryngological findings identified significant improvements that are rarely described in the literature. CONCLUSION: the studied vocal techniques are capable to provide significant immediate improvement of vocal quality and laryngeal configuration.
