Lots of computer simulations show that the proposed CASA speech enhancement algorithm can improve the output SNR (about 10 dB) and the understandable ability of the outputs distinctly in both case of using the car noise and the white noise.

• 通过在汽车噪声和白噪声干扰下的仿真实验结果表明 ,简化的 CASA模型语音增强算法的输出信噪比约提高了 1 0 d B,且可以有效抑制干扰噪声的听觉影响 ,增强输出语音信号的可懂度
