| Abstract: | 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. |
