Is Cepstral Peak Prominence a Measure of Vocal Fatigue in Temple Priests: A Pilot Study.

Purpose: Considering cepstral analysis of voice as a measure of overall severity of dysphonia, we tried to investigate if these measures could be considered as a metric of vocal fatigue as well. Since voice quality changes are seen as a result of vocal fatigue, we wanted to find out if there were any correlations between the cepstral measures, vocal fatigue symptoms, and auditory perceptual evaluation of voice in professional voice users.

Method: The pilot study was conducted on 10 temple priests belonging to the Krishna Consciousness Movement.
