Speech analysis and synthesis method based on harmonic model and source-vocal tract decomposition

摘要

This invention discloses a speech analysis/synthesis method and a simplified form of such a method. Based on a harmonic model, the present method decomposes the parameters of the harmonic model into glottal source characteristics and vocal tract characteristics in its analysis stage and recombines the glottal source and vocal tract characteristics into harmonic model parameters in its synthesis stage.
