摘要

基于 TC264微处理器自主设计了一款语音控制的声源定位演示仪。采用 3D 建模软件creo3 设计并打印了新型麦克风阵列拓扑结构，将麦克风阵列采集到的声源信息传输到 TC264 微处理器中，应用时延估计算法（TDOA）实现了声源准确定位，并采用 LD3320芯片对声音进行识别，实现了对整个系统的辅助人声控制。同时在上位机中利用QT（应用程序开发框架）开发了一款windows 系统下用于上位和底层平台进行交互的应用软件，实现了串口通信助手、多通道声音波形显示、定位结果显示等多种功能。

Abstract:

The sound source location demonstration instrument is designed based on 'TC264 microprocessor.The new microphone array topology was designed and printed by 3D modeling software creo 3 ,and the sound souree information collected by the microphone array was transmitted to TC264 microprocessor for calculation byT'DOA algorithm to realize the sound source location.The demonstration instrument uses L.D3320 chip toidentify the sound and realize the auxiliary human voice control of the whole system.At the same time , based onO'T( application development framework ) , the windows application sotware is designed for the interactiorbetween the upper system and the underlying platform , which realizes the serial port communication assistant, multi-channel sound waveform display ,location result display and other functions.

Key words: TC264 TD0A algorithm microphone array topology sound source location voice conrtol
