摘要
本文提出了倒谱分析和基频提取的新方法,即把离散余弦或正弦变换引入到倒谱分析上来,把原倒谱分析中所用的离散付氏变换(DFT)用离散余弦/正弦变换(DCT/DST)代替.此法具有一定的实用价值.
A new method in the cepstrum analysis and Pitch extraction, in which the Discrete Cosine/Sine Transform (DCT/DST)has been introduced into the cepstrum technique, is proposed. DCT/DST has taken the place of DFT which was used in the conventional cepstrum technique. This method has fair value.
