Research Abstract

In this research, a new speech coding system based on ML-BEATS has been developed. ML-BEATS method can split an input sequence into many sub-sequences and cluster these. This method has been applied to segment quantization. Experimental results showed the proposed method decreased bit rate, but increased spectral distortion compared with the G.729.
