Welcome to the Vocal Development Lab website! We are located in the Department of Communication Sciences and Disorders in the College of Public Health at Temple University. Our work focuses on voice disorders across the lifespan, with a special emphasis on the development of voice and speech in children with and without communication disorders

One of our primary aims is to improve the treatment of children with voice disorders. To do this, we must understand how voice, speech, and perception develop during childhood. Our goals are to understand why some children have differences in their vocal control and how this relates to other aspects of communication development. Directed by Dr. Liz Heller Murray, the Vocal Development Lab strives to make voice therapy for children more effective, efficient, and accessible.
