Measures on wavelet segmentation of speech

Speech segmentation is widely used in many speech applications. We propose a new wavelet-based extension of the typical spectrum-based non-uniform speech segmentation methods. The use of wavelets i mproves computation performance and provides easy and flexible adjusting of algorithm parameters. Segmentation accuracy measures are introduced and applied for evaluation as well.
