低功耗微型三传声器阵列语音采集系统设计

Design of Low Power Small Microphone Array Speech Data Acquisition System

基于低功耗单片机MSP430F427和USB2.0控制器CY7C68013,开发了一种面向三传声器阵列的语音数据采集系统。讨论了如何实现3路语音数据的同步采集、存储,以及USB2.0数据回传及后处理等问题。本系统具有体积小、功耗低、可扩展性好的特点。

A design of low power small microphone array speech data acquisition system using MSP430F427 and CY7C68013 is described. The method to acquire and store three channels data synchronously is discussed. The problem of USB2.0 data communication and data post-disposal is assressed. The system is low power consumption, small size and good expansibility.
