Abstract
Vocal fatigue is a frequently reported voicec symptom among professional voice users. Indian School teachers teach lontinuously for many hours in advene acoustical environments and are highly susceptible to vocal fatigue. The present study is the first to examine acoustic voice measures in teacher, reporting naturally induced vocal fatigue. 40 female primary school teachers (mean age =36 yearn) with varying severity of vocal fatigue participated in this studr. Voice measures of minimum and maximum fundametal frequency were obtained before and after one and a half hours of continuous teaching at the workplace. Maximum fundamental frequent was an important acoustic parameter in determining presence of weal fatigue. Most cummin perceptual sympioms include throat dryneis, discomfort and loss of voit e. The rule of vocal hygiene and warm-up in reducing vocal fatigue are considered.
