To improve speech patterns of deaf children, a visual aid was developed which assists in the training of velar control. A small accelerometer is attached to the nose, and its output presented on a computer-controlled visual display. The display then may be used as a training aid, or for analyzing recorded or live speech. Properties of accelerometer output in speech of people with normal hearing and children with severely impaired hearing are compared. The data show inadequate velar control, particularly improper nasalization of certain vowels for a significant number of deaf children. Some comments are made on the development of procedures for the training of velar control using the display as an aid. (SK)
