  1. 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

    本文基於感覺加權相位譜分析合成（ 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。
  2. Waveform interpolation as a great potential speech coder has got much attention

    波形內插（ wi ? ? waveforminterpolation ）作為一種極具潛力的語音編碼方法受到了人們的關注。
  3. The goal of this thesis is to develop a kind of 2kbps wi speech coder based on waveform interpolation ( wi ) coding at 3. 75 kbps, and have it simulated on computer by c language. in this thesis, the existing wi model has been improved

    本文的主要目標是在現有的3 . 75kbps波形內插（ wi ? waveforminterpolation ）演算法的基礎上，開發一個速率為2kbps的wi編碼器，並用c語言在計算機上模擬實現。
  4. In the wi coder, the speech signal is represented by an evolving characteristic waveform ( cw ). the cw is decomposed into a slowly evolving waveform ( sew ) and a rapidly evolving waveform ( rew ), representing the quasi - periodic and non - periodic components of speech, respectively

    Wi編碼器將語音信號表示為漸變的特徵波形（ cw ? characteristicwaveform ） ，然後將其分解為慢漸變波形（ sew ? slowlyevolvingwaveform ）和快漸變波形（ rew ? rapidlyevolvingwaveform ） ，分別表示語音的準周期成分和類噪聲成分。
