RESUMO

describe the acoustic vocal modifications occurred after the vocal technique of the high-pitched sound in young adult women without voice complaints and with normal larynx, it was done through Multi-Dimensional Voice Program. Method: 23 subjects participated in the study who signed the Statement of Free and Informed Consent, completed a questionnaire, the ear, nose and throat evaluation performed with indirect laryngoscopy; stomatognatic system evaluation and hearing screening. They have done the high-pitched sound in three series of fifteen repetitions, maximum time speech with tone and intensity usual, with intervals of 30 seconds of rest between each series. There s a digital recording issue of sustained vowel /a/, before and after they have done the series, which were analyzed acoustically. Results: in acoustic voice evaluation, there was no statistical significance in any of the measures offered by the program. It was noticed after the high-pitched sound, a trend of increasing measures of Average Fundamental Frequency, Highest Fundamental Frequency, Lowest Fundamental Frequency, Absolute Jitter, Jitter Percent, Relative Average Perturbation, and Pitch Perturbation Quotient, reduction of measures of Standard Deviation of f0, Smoothed Pitch Perturbation Quotient, Fundamental Frequency Variation, Shimmer in dB, Shimmer Percent, Amplitude Perturbation Quotient, Smoothed Amplitude Perturbation Quotient, Peak-to-Peak Amplitude Variation, Noise to Harmonic Ratio, Voice Turbulence Index, Soft Phonation Index, F0- Tremor Intensity Index, Amplitude Tremor Intensity Index, Degree of Sub-harmonics, Degree of Voiceless, Number of Sub-harmonic Segments and Number of Unvoiced Segments and there was no change in measures of Degree of Voice Breaks and Number of Voice Breaks. Conclusion: It is suggested that in this group, the high-pitched sound showed no significant effect on the voice signal with reduction of noise, reduction of exhaust air, grater stability of the emission, and increased of highest and lowest frequency.
