【摘要】 用麦克风阵列进行语音处理的方法可以提高信噪比,解决环境噪声,回声和混响引起的语音识别性能降低的问题,麦克风阵列系统是由一组按一定几何结构摆放的麦克组成的系统。此阵列能接收空间传播信号,经过适当的信号处理,提取所需的信号源和信号属性等信息。使用该系统可大大提高强干扰环境下的语音识别性能。更多还原

【Abstract】 Speech progress using microphone arrays can promote SNR, solve the reduction of recognition′s performance because of environment noise, echo and reverberation. Microphone arrays system is composed of a serial of microphones put with special geometrical structure. It can get space radiate signal and pick-up the needed signal resource and attribute through appreciate signal processing. The recognition’s performance can be greatly increased under strong disturb environment using this system.更多还原
