本文描述了波形插值语音分析与合成方法的基本原理和编码技术，并给出一种2．4kbps波形插值声码器的实际结构.该声码器利用提取特征波形及浊/清音成分分离的方法，有效地去除了残差信号中基音波形的冗余度，能在2．4kbps数据率下获得高质量的合成语音．
In this paper, the basic principle and coding technique of waveform interpolation speech analysis and synthesis method are described, and the actual structure of a 2.4kbps waveform interpolation vocoder is given.The vocoder utilizes the method of extracting the characteristic waveform and separating the voiced / unvoiced components , Effectively removing the redundancy of the pitch waveform in the residual signal and obtaining high quality synthesized speech at a data rate of 2.4 kbps.
