Abstract

We have designed and built a portable real-time speech processing system, which incorporates a TMS 32010 (i.e. a co-processor) within an IBM personal computer. The system design is discussed as is the speech therapy software that has been implemented. Displays of loudness, pitch and vocal tract cross-section as computed by the system are illustrated. Preliminary results show that an estimate of the glottal excitation, as extracted using shift-and-add, vary between individuals. We indicate why the estimate of the glottal excitation may be useful in the diagnosis of glottal disorders.
