vector quantizer designing based on robust statistic 基于穩(wěn)健統(tǒng)計的矢量量化器設(shè)計算法
Moreover, a predictive phase vector quantizer is proposed in this thesis based on the above method . the synthesis speech is slightly improved for female speakers 此外,本文在此基礎(chǔ)上提出了一種相位預測式矢量量化方案,使得女聲的語音合成質(zhì)量有所改進。
In order to obtain a high-quality speech codec, the phase information of speech should be included in codec . in this thesis, a method for quantizing the phase of sew ( slowly evolving waveform ) and reconstructing sew ’ s phase with cubic polynomial interpolation is given based on the perceptual weighting analysis-by-synthesis ( a-b-s ) vector quantizer for the phase spectrum in wi coder 本文基于感覺加權(quán)相位譜分析合成(abs-analysis-by-synthesis)矢量量化方法,給出了一種wi編碼器中慢漸變波形(sew-slowlyevolvingwaveform)的相位信息量化及合成端相位的三次多項式插值重建方法。
