Effect of a Voice Training Program on Acoustic Voice Parameters in Secondary School Teachers
Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 5
Abstract
Teachers are known to be vulnerable to voice disorders because of the excessive use of their voice for professional purposes. This study aimed to investigate the effects of a vocal training program on select acoustic voice parameters in secondary school teachers. The study sample comprised 60 premenopausal female secondary school teachers. The subjects were divided into the experimental (n = 30) and control (n = 30) groups. The experimental group underwent a vocal training program for 15 days, whereas the control group did not receive any training. The training included a combination of yogic and vocal function exercises. Results showed significant differences in the post-training values of fundamental frequency, jitter (%), relative average perturbation, pitch perturbation quotient, shimmer (dB), amplitude perturbation quotient, and noise-to-harmonic ratio between the experimental and control groups. Thus, the vocal training program showed positive effects on the voice quality of secondary school teachers.
