Deirdre Michael

Assistant Professor


I have been a Speech-Language Pathologist specializing in voice and upper airway disorders for over 30 years.  I have also been a singing teacher for over 45 years, and continue to perform in a variety of venues.  While my research passion is the perception of voice quality, my educational passion is to make voice science accessible to the lay singing community.  Along with Dr. George S. Goding, I co-founded the Lions Voice Clinic in 1995.
