摘要:基于语音状态模型的语音增强算法是当前语音信号处理的研究热点。把通常的LPC语音模型修正后,将得到两个语音模型:时变AR 模型、时变双AR模型。但是利用这些模型增强语音时,都没有考虑到语音的清音、浊音区别。为此本文引入了语音清浊音状态空间模型,这种模型在描述语音方面比时变AR模型、时变双AR模型要强,而且物理含义明显 同时在用含噪语音信号预测纯净语音信号时,引入遗忘因子和粒子滤波算法以降低计算复杂性,减小运算量。实验证明,增强后的语音信号信噪比有一定提高.且优于传统的LPC模型.

TOOL (Tiny Object Oriented Language) is an easily-embedded, object-oriented, C++-like-language interpreter. The language, and indeed a significant part of the core of the TOOL engine, is based on the BOB project, a work that was originally developed by David Betz covered in previously published issues of Dr. Dobb s Journal.
