A lightweight accelerometer has been used to produce a waveform related to the glottal acoustic output when attached to the throat of a speaker, and to provide an indication of acoustic coupling to the nasal cavities when attached to the external surface of the nose. Examples of signals produced by the accelerometer are shown, and possible…

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…

A three-year project developed a computer-based system of speech-training aids for the deaf, formulated speech-training procedures that utilize the system, and evaluated these procedures. The first year was devoted to development of the system; in succeeding years it was employed in a remedial speech-training program at Clarke School for the Deaf.…
