This paper is concerned speech segmentation for a variable frame-rate (VFR) vocoder. The segmentation is done on the basis of transitivity functions which measure the rate of change of spectral or excitation parameters derived from speech. It has been found that significant data reductions can be achieved without loss of synthetic speech quality.
