Primary Outcome Measures:
  • Fiberoptic endoscopic evaluation [ Time Frame: One year ]
  • Score(CAPE_V); score(PPAV); score on acoustic analysis [ Time Frame: One year ]

Enrollment: 162
Study Start Date: September 2010
Study Completion Date: March 2013
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Function Voice Exercises
Behavioral: Function Voice Exercises Patients will receive 6 sessions of therapy over a course of 6 weeks, with one session per week.
Behavioral: Function Voice Exercises
Function Voice Exercises Patients will receive 6 sessions of therapy over a course of 6 weeks, with one session per week.
Experimental: Voice amplification
Behavioral: Voice amplification Patients will use VA over a course of 6 weeks.
Behavioral: Voice Amplification
Behavioral: Voice Amplification. Patients use VA over a course of 6 weeks Control group. No treatment over a course of 6 weeks.

Detailed Description:
Both approaches combined with Vocal Hygiene Program (Behlau, 2007).The target population are female teachers because they have the highest risk for developing voice problems. For this study the investigators are primarily interested in seeing if Vocal Functional Exercises and Voice Amplification are equally effective at improving vocal functioning in teachers with voice disorders. The Fiberoptic endoscopic evaluation will be done before randomization. All the participants will complete before and after a 6-week treatment phase (a) Voice Activity and Participation Profile (PPAV), an instrument designed to appraise the self-perceived psychosocial consequences of voice disorders to assess the impact of voice disorders on daily activities (b) Audio voice recording for later acoustic analysis, through the Kay Elemetrics Multi Dimensional Voice Program (c) Audio recording for later perceptual analysis through Consensus Auditory-Perceptual Evaluation of Voice (CAPE_V). It is believed that the search for evidence in clinical studies like this can contribute to awareness programs and vocal training for teachers.
