Abstract

Statistics and analysis of residual FM parameters correlation of male and female voices in English and Chinese, an algorithm for the dimensionality reduction of residual FM parameters based on two-dimensional DCT transform is presented. Remarkable reduction of the correlation of residual fm parameters is obtained. In multi-frame joint coding, DCT dimensionality reduction algorithm achieves coded bits down to 66% in speech coding without reducing the auditory performance. Using residual FM parameters DCT-based model, the encoding rate can be further reduced while maintaining the same voice quality.
