Abstract

Speech coders invariably spend about 1/3 of their bits replicating a number of effects collectively termed “excitation”. The need for so much bandwidth stems from two causes. The frame rate must be relatively high, because transient changes must be resolved. The data needed for each frame is high because unpredictable broad-band components must be reproduced. In this paper, we discuss three projects to learn more about these elusive aspects of speech. One project models the transient behavior. Two others seek to characterize stochastic processes that accompany periodic vibration in voiced sounds
