<p>To work as a voice therapist requires certification in almost every state, through speech pathology accreditation. It has absolutely nothing to do with music therapy, but rather voice therapy addresses acute and chronic functional and organic vocal dysfunctions. While speech timbre and efficiency is part of the evaluation process of the voice therapist, singers are the most sensitive to variations in their voices and they and their teachers are most likely to seek the help of a professional who can diagnose and guide a recovery process (sometimes medical intervention is needed, but most often functional voice therapy is successful, even when there is a functionally caused physical abnormality). Most good voice teachers, who carefully monitor and teach technical issues, do “voice therapy” but professional speech pathologists claim this arena of care. However, when this field was in its infancy, it was certain reknown voice teachers who actually taught medical students, instructing them as to vocal sounds, functions, ranges, etc., and how the voice teacher would coax and guide a healthy function from the voice. </p>
<p>The most successful approach to combining these two fields would be to consider a double major in voice and speech pathology, perhaps through a BS or BA program. I do not think there are any voice therapy majors offered within music curriculums because of the accreditation requirements. Good luck.</p>
