Microprocessor-based speech processing system.
Durational measurements of frication, aspiration, prevoicing, and voice onset are often difficult to perform from the spectrogram, and the resolution is limited to about 5 ms. In many instances, a higher resolution can be obtained from a study of waveforms than from a study of spectrum. We present a microprocessor-based speech acquisition and processing system which uses waveform analysis techniques to extract measurements from the acoustic signal. The system is low cost and portable; it operates in "real time" and employs noninvasive data-capturing techniques. The usefulness of the system is demonstrated in the VOT measurement of CV clusters and in the measurement of fundamental frequency.
