Speech Enhancement Based On AUnvoiced-Voiced Model
- 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.

- 自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。-Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, wit
