摘　　要：本文提出了一种特定噪声抑制方法,其目的是利用回声消除算法将非稳态噪声干扰信号作为噪声参考信号输入,并通过自适应滤波算法将厨卫设备工作时所接收到的非稳态噪声进行抑制处理,提高设备在工作状态下语音识别控制的准确率。同时对比分析了几种主流的自适应滤波算法,通过实验仿真结果选取最优的自适应滤波算法,验证了该噪声抑制方法在特定应用条件下可以有效的滤除影响语音识别性能的噪声。This paper proposes a specific noise suppression method,which aims to use the echo cancellation algorithm to input the unsteady noise interference signal as the noise reference signal, and to use the adaptive filtering algorithm to obtain the instability of the kitchen and bathroom equipment. The state noise is suppressed to improve the accuracy of the speech recognition control under the working condition of the device. At the same time, several mainstream adaptive filtering algorithms are compared and analyzed. The optimal adaptive filtering algorithm is selected by experimental simulation results. It is verified that the noise suppression method can effectively filter out the noise affecting speech recognition performance under specific application conditions.
