Therefore, the speech signal enhancement technique, automatic control engineering and room acoustics are used to solve the very problem the noise, interference problem in the voice control technique for household appliances In this paper, the adaptive noise cancelling ( ANC ) system is designed. 指出,电视机等电器发出的语声,是最为严重的干扰噪声。为此,本文引入ANC方法这一有效的语音增强技术,提出了一种用于家用电器声控制技术的干扰噪声消除方案。
