Use of articulatory synthesis for analysis of voice disorders

Peter Howell, Mark Williams

A software articulatory synthesizer based on Ishizaka and Flanagan (1972) is used to reproduce the glottal volume velocities of stuttered and fluent vowels as spoken by children and teenagers. The use of the articulatory synthesis model allows a physiological interpretation of the different laryngeal adjustment in dysfluent speech. This is applied to the speech of stuttering teenagers and children.
