语音信号的前反馈自适应量化

The Quantification of Self-Adaptability to The Front-Response for Phonetic Signal

提出了复杂语音信号的前反馈自适应量化方案,分析了其量化过程.不同量化器均采用该方案,对语音信号进行量化,比较量化结果,可知该方案能够大大提高信噪比.

Quantification scheme of self-adaptability to the front-response for phonetic signals is put forward.Its quantified process is analysed.Different quantifiers are used in the scheme,and phonetic signals are tri-quantified.The comparison between quantified results shows that this scheme can greatly improve the rate of signals and noises.
