A 3-D Virtual Head as a Tool for Speech Therapy for Children

Sascha Fagel, Katja Madany

A virtual talking head was adapted to show articulatory movements of the lips, jaw, tongue, and velum. A JavaScript program with a graphical user interface in HTML was developed for speech therapists to use the talking head as a tool in speech therapy. In an initial study children's productions of words containing the sounds /s/ and /z/ were recorded and evaluated before and after two short learning lessons with an experimenter using the virtual head to explain the correct (prototypic) pronunciation of these sounds. Results show that several children could significantly enhance their speech production of the /s,z/ sound.
