摘要
介绍了传声器阵列语音拾取和传输的基本原理,给出了系统各个模块的设计方案和实现方法。采用FPGA实现多路音频信号复用和传输,完成了大型传声器阵列的结构设计。该系统稳健性能高、扩展性良好、多路语音数据有较高的同步性。在大型互动游戏环境中能方便地完成人机语音指令交互。
The basic principle of microphone array speech acquisition and transmission is introduced,a design scheme of system modules and the realization method are presented. Multichannel audio signal multiplexing and transmission is realized by using FP- GA ,the structure design of a large -scale microphone array is completed. The system is stable, good extensibility and has high syn- chronization accuracy. In large - scale interactive gangs it can conveniently complete nmn - machine interaction voice commands.
