Objective: Accomplish the immediately effects in both technique high oral oscillation and LaxVox with different time performing in subjects with healthy voices. Methods: Thirty subjects female and male with ages varying from 18 to 50 years old will be. After sign off the documentations they will respond questions about voice self-assessment, vocal and laryngeal symptoms; They will be submitted to a vocal sample with vocal emission of /a/, counting numbers 1 to 20 and spontaneous speech to further perceptual auditory. Then, on the first meet will be picked the technique that will be realized by the subject in a period of one minute. After one minute, the same proceeding of vocal register will be performed again and after that, the subject will respond questions about self-assessment. After assorting the technique, the same procedures of vocal sample will be repeated a self-assessment questionnaire that will investigate the effects of voice and laryngeal sensations, articulation and breathing of those techniques. The data will be analyzed by parametric tests, to compare data before and after the procedure of voiced tongue vibration technique and high frequency oral oscillation, as well to compare the groups and time performing.
