Description: duction techniques proposed in the art are expressed as a spectral
gain depending on the a priori SNR. In the well-known decision-
directed approach, the a priori SNR depends on the speech spec-
trum estimation in the previous frame. As a consequence the gain
function matches the previous frame rather than the current one
which degrades the noise reduction performance. We propose a
new method called Two-Step Noise Reduction (TSNR) technique
which solves this problem while maintaining the benefi ts of the
decision-directed approach. This method is analyzed and results
in voice communication and speech recognition context are given.-noise estimate Platform: |

Description: 谱减算法为最早的语音降噪算法之一，它的提出，基于一个简单的原理：假设语音中的噪声只有加性噪声，只要将带噪语音谱减去噪声谱，就可以得到纯净语音幅度。这么做的前提是噪声信号是平稳的或者缓慢变化的-Spectral subtraction algorithm is one of the first voice noise reduction algorithm, which has been proposed, based on a simple principle: if only the voice of the noise additive noise, just noisy speech spectrum subtracting the noise spectrum, you can get clean speech amplitude . Do so on the premise that the noise signal is stationary or slowly varying Platform: |
