中文摘要 | To suppress the directional noise in miniaturized speech communication devices, a dual-channel speech enhancement method was developed. A first-order differential microphone (FDM) array was used, together with , single-channel spectral enhancement techniques to simultaneously obtain estimates of the speech and the noise simultaneously, and correct the noise spectrum in real-time. This method achieves a 2 - 6 dB output signal-to-noise ratio gain compared with existing dual-channel speech enhancement techniques, with 2/3 computational complexity saved. Simulations show that the techniques effectively improves the noise reduction performance of the algorithm and is more suitable for real-time speech enhancement systems. |
