Abstract Immediate effects of an exercise with the vocal tract semi-closed.Objective: To investigate the immediate effects of the phonation exercise in a straw in individuals with and without vocal fold lesions.Materials and Methods: Prospective study. 48 individuals, aged between 18 and 55 years participated in the study, and they were distributed into two groups: GL- with a benign vocal fold lesion; GSL-without a lesion. The following analyses were carried out before and after the straw phonation exercises: voice self-analysis, [El vowel auditory-perception analysis, selected parameters acoustics (VoxMetria 2.6) and vicleolaryngoscopy.Results: The vocal self assessment indicated a statistically significant improvement on voice emission in GL individuals (p=0.015). There were no statistically significant differences before and after the exercise and between the groups, in the videolaryngoscopy, acoustic and auditory-perception assessments.Conclusion: The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation.
