Abstract

Abstract

An improved method is presented on the base of the study for the discrete-amplitude multi-resolution speech coding. New coding format is adopted through statistical analysis for signal amplitude. Then the indented adapting bit allocation is employed. Theoretical analysis and experimental results show that improved coding method can farther reduce the coding rate maintaining the same speech quality.
