[Speech/Voice recognition/combine] BackGround_Noise_Cancellation DL : 0: The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic distortion in the enhanced speech.

[Speech/Voice recognition/combine] noise_reduction_technique DL : 0: 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
