Resumo: |
Voice is produced by the vibration of the vocal folds expressed by its fundamental frequency (f0 Hz), while the formants (F) are f0 multiples, indicating amplification zones of the vowels in the vocal tract. The isolated growth hormone (GH) deficiency (IGHD) characterizes high pitch voice, with higher values of formants frequencies, maintaining a prepuberal acoustic prediction. We speculated that acoustic vocal parameters can be improved by SOVTT or choir training, and that their voice suits distribution resembles an infantile choir. Objectives: verify the effect of therapy with semi-fluid vocal tract exercise (SOVTT); evaluate the effect of coral training; and to analyze the classification of voice suits in the choir of subjects with DIGH. METHODS: prospective longitudinal study without a control group evaluated the effects of SOVTT therapy on LaxVox silicone tubing and coral training on 17 adults with congenital, untreated IGHD individuals over a 30-day period. The vocal sample of the vowel [é] was recorded for acoustic analysis and comparison at three moments of the effect before and after the SOVTT (pre- SOVTT and post- SOVTT) and post-training choir. In addition, classification of the voices of the choir voices of individuals with IGHD was performed. Results: The first formant (F1) was higher in moment post-training compared to the pre- SOVTT (p = 0.009). The second formant (F2) was higher in post-SOVTT in comparison to pre- SOVTT (p= 0.045). Shimmer was reduced in post-training in comparison to pre-SOVTT (p= 0.045). All ten IGHD women were all altos, and all seven IGHD men were tenors. Conclusions: An approach to speech therapy with SOVTT and choir training was able to improve acoustic parameters of the voice of individuals with congenital and untreated IGHD. In particular, this appears to be important in a scenario in which few patients undergo GH replacement therapy. It is concluded that the effect of the therapy with SOVTT is added to coral training favoring adjustments of the source in the adduction of the vocal folds and the filter in the form, length and constriction of the vocal tract. The classification of voices of the choir voices of adult individuals IGHD is typical of an infantile choir. |
