摘　　要：由于车内噪声的干扰,车载语音系统通讯质量较低,研究车载语音系统降噪技术非常必要.语音降噪技术的方法有很多,本文选取一般谱减法、自适应降噪法和小波降噪法进行仿真对比实验,分析比较它们的优缺点,得出小波降噪在语音信号降噪方面具有优越性.At present, Human - computer interaction technology has developed rapidly. Voice is the most convenient way to communicate, but the internal noise reduces the quality of the communication, so the research on speech denoising on car audio system is absolutely necessary. There are many methods to denoise. This paper selected three typical methods to do the simulation test, and analyzed the advantage and disadvantage between each other.
