摘　　要：语音是用于信息交流的重要媒介,清晰的提取语音信号是准确信息传递的前提,面对日益复杂的声场环境,麦克风阵列系统以优异的性能逐渐替代单麦克风系统。为了更好地应用麦克风阵列实现语音定位与增强,设计了一款包含低噪声前置放大器、信号调理电路和高速多路同步采集ADC的麦克风阵列系统。经过试验,该系统能够清晰准确地实现多路语音信号采集。Speech is an important medium for information communication.Clear speech extraction is the premise of accurate information transmission.In the face of increasingly complex sound field environment,microp hone array system gradually replace single microphone system with excellent performance.In order to better use microphone array to achieve speech location and enhancement,a microphone array system including a low noise preamplifier,a signal conditioning circuit and a high-speed multi-channel synchronous acquisition ADC is designed.Through the experiment,the system can realize the acquisition of multi voice signal clearly and accurately.
