| 摘 要： | 噪声估计是变噪声电平环境下语音增强的关键。针对传统搜索频谱最小值方法延迟较大的缺点,提出了最小频带能量算法,加快语音帧内大部分噪声的更新速度。实验结果表明,该算法对电平随时间变化的噪声取得了较好的增强效果。

| Abstract: | Noise estimation is the key factor of speech enhancement in variable noise-level environments. Aiming at the longer delay in the searching minimum of the noisy speech spectrum, a novel minimum band energy approach is proposed to speed up noise update. The simulation on computer shows that the proposed algorithm is more effective than the searching minimum method of the noisy speech spectrum in variable noise-level environments. |
