【摘要】 实现了一种等边三角形结构微型传声器阵列的语音增强方法。不同于以往的线性一阶差分传声器阵列结构和线性二阶差分传声器阵列结构,提出并且验证了一种基于延时相加的二阶三角差分传声器阵列的算法,通过真实环境的检测,证明该算法能够实现12个方向的语音增强,同时方向性信噪比比线性一阶差分传声器阵列增强3～4dB。更多还原

【Abstract】 A speech enhancement method based on regular triangle topology is implemented. It is different from the original version of first order and second order differential microphone arrays based on linear topology. A second order differential microphone array based on regular triangle topology is proposed and fulfilled, the algorithm is able to enhance twelve directions and the SNR is enhanced 3 to 4 dB compared with first order linear microphone arrays.更多还原
