摘要
本文提出了一种关于滤波器间相似性度的定义及计算相似度的方法。并将其应用于基于分析－合成（Ａｎａｌｙｓｉｓ－ｂｙ－Ｓｙｎｔｈｅｓｉｓ）的线性预测编码中，可以在对再生语音质量影响较小的情况下，大大降低编码的码率。
A definition of similarity between linear filters is proposed in this paper and it's calculation is also proposed. When the definition is used in speech coding based on analysis-by-synthesis, it can greatly reduce the bit-rate without distinct damage to the synthetic speech quality.
