Abstract: Professional voice users are those who directly depend on vocal communication for their livelihood. They are also considered atheistic voice users because their voice is more extensive and tough than that of non-professional voice users. Vocal fatigue is the main symptom seen in professional voice users; it is usually described as a negative sensory vocal symptom that corresponds to a change in the vocal response. Among the professional group, prevalence of voice disorder is higher among teachers who intensively used their voice at work than in other professional groups whose activities do not involve increased voice effort. Acoustic analysis of voice is one of the most appealing methods for assessing phonatory function or laryngeal disease. The maximum phonation duration is the longest time that a client can sustain a vowel sound at a comfortable pitch and loudness on a deep breath. The aim of the study was to compare maximum phonation time (MPT) in pre-school teachers and college lecturers. Using PRAAT, MPT of 20 pre-school teachers and 20 college lectures voice recorded and analyzed. Results concluded that pre-school teachers have lesser phonation time than college lecturers due to vocal abuse.
