摘要 提出一种基于快速噪声估计的MMSE语音增强算法,实验表明这种算法比起谱相减法和基于语音短时对数谱的最小均方误差(MMSE-LSA)算法能更显著地提高算法的客观性能,在非平稳噪声环境中能快速估计出变化的噪声功率谱。 A fast noise-estimation algorithm used in the speech enhancement algorithm of MMSE is studied.Experiments results prove that this algorithm can dramatically improve objective performance compared with spectrum subtraction algorithm and MMSE-LSA algorithm,and it can estimate the noise spectrum quickly in the non-stationary noise environment.
