摘要: A speech coding system (10) and associated method relies on a encoder (15) decoder (20). The (20) includes harmonic generator (70) which modulates the phase of each generated with low frequency, bandwidth signal to remove buzzy quality produce natural sounding speech. amplitude modulating is adjusted in accordance magnitude. For harmonics residing spectral valley relatively large for near peaks, modulation small.
