- 语音信号的频域处理,语音虽然是一个时变、非平稳的随机过程。但在短时间内可近似看作是平稳的。因此如果能从带噪语音的短时谱中估计出“纯净”语音的短时谱,即可达到语音增强的目的。由于噪声也是随机过程,因此这种估计只能建立在统计模型基础上。利用人耳感知对语音频谱分量的相位不敏感的特性,这类语音增强算法主要针对短时谱的幅度估计。 -voice signals in the frequency domain processing, voice is a time-varying, nonstationa

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.
