A miniature accelerometer for detecting glottal waveforms and nasalization.
A lightweight accelerometer has been used to obtain a waveform related to the glottal acoustic output when attached to the neck 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 clinical applications are discussed.
