Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Voice therapy is the standard-of-care for many of the nearly 140 million people in the United States who suffer from voice disorders,1 yet patients claim that current therapies are ineffective at meeting their voice needs.2 Published data by our research team indicate that patients think that transfer of target voice techniques to every day voice use (i.e. conversation) is the most difficult aspect of therapy,2 and that training techniques in conversation is the most useful aspect of voice therapy.2 Unfortunately, traditional voice therapy programs spend little, if any, time training voice techniques in conversation.3 This lack of functional specificity in voice therapy may contribute to the estimated 65% attrition rate.4 Even after some form of treatment, patients are still struggling with daily conversational voice use, and voice disorders continue to cause serious disability, stress and depression, which negatively affects social functioning and job performance.5 A new voice therapy program, Conversation Training Therapy (CTT), based on published patient reports on dissatisfaction with traditional therapy, was developed by the Investigators. It was honed with recommendations from expert clinical voice-specialized speech-language pathologists, and successfully piloted in a small case series of patients with voice problems. The investigators objective in this application is to test CTT in the rehabilitation of patients with voice disorders. The investigators hypothesize that, as demonstrated in the investigators preliminary case studies, these methods will result in early treatment success, and reduce the time required to reach therapeutic goals, thereby reducing costs associated with voice treatment.
