Voicing measure as an estimate of signal periodicity for a frequency domain interpolative speech codec system |
摘要 |
A system determines a voicing measure as a measure of the degree of signal periodicity and uses the determined voicing measure to quantize the spectral magnitude of the slowly evolving waveform (SEW) and the modeling of the SEW and rapidly evolving waveform (REW) phase spectra.
