Brief summary

The study compares two different forms of voice therapy, Lessac-Madsen Resonant Voice Therapy and Casper-Based Confidential Flow Therapy. The target population are teachers because they have the highest risk for developing voice problems. For this study the investigators are primarily interested in seeing if Lessac-Madsen Resonant Voice Therapy (LMRVT) and Casper-Based Confidential Flow Therapy (CBCFT) are equally effective at improving vocal functioning in teachers with phonotrauma, as assessed by the Voice Handicap Index (VHI).

Interventions

Patients receive 8 sessions of therapy over a course of 4 weeks, with one double session per week.
