| Abstract: | We presented a new Voice Activity Detection algorithm with combined employment of short-time energy, short-time zero crossing rate and short-time auto-correlation. The application was implemented using the circuit based on the DSP chip TMSvc5402,and run in a radio/PSTN network auto switch system. The VAD algorithm has a good performance in the system and can fulfill the auto control of communication progress by the speaker' s voice. |
