| 摘 要： | 针对非平稳环境下噪声估计和语音增强性能降低的特点,提出一种基于Bark域的快速自适应噪声谱估计算法。它基于听觉模型,将带噪信号变换到Bark域,并在Bark域内实现基于人耳掩蔽的语音增强。仿真实验表明该算法能充分利用Bark带内频带间的相关性,跟踪快变的背景噪声,提高语音增强性能,减少运算量和复杂度。

| Abstract: | Aiming at the decline of performance of noise estimation and speech enhancement in unstable circumstance,this paper presents a quickly self-adaptive noise spectrum estimation algorithm in Bark domain.The new algorithm based on the perceptual model transforms the noisy signal from frequency domain to Bark domain,and executes speech enhancement based on masking properties in Bark domain.Simulation experiment shows the algorithm can make full use of the correlation among frequency bins in the same Bark band,tr... |
