%X In this paper,a method of Real-time Voice Activity Detection(VAD)based on DSP was proposed.After configuring Interrupt Service Routine(ISR),the audio data was saved through parallel processing of DSP and DMA based on the method of Short-term energy state-switch process.A control board was designed to implement program control function.Experimental result shows that the data of storage account for 94.98% of the marked in the DSP system,so as to realize the real time processing of voice.
