Glottal wave coding and synthesis based on pitch synchronous voice source signal processing

This paper proposes the voice source signal process technology platform based on pitch synchronous, in which mainly to complete extraction of glottal wave analysis and synthesis, including voiced and unvoiced detection, glottal closure instants detection in the voiced segments, and extraction of glottal wave, glottal wave coding and synthesis. Meanwhile, LF model and its parameters would be analyzed and calculated which evaluation the effect of phonation source, including glottal open quotient (OQ), closing quotient (CQ), speed quotient (SQ), amplitude quotient (AQ) and spectral tilt frequency.
