| Abstract: | According to the need of simulation of four wire access programcontrolled telephone network, through the voice detection technology of 2/4 wire conversion voice, a voice detection is realized by using DSP technology solutions. The scheme by DSP chip is simulated two line voice cut through voice detection, sound technology such as simulating two lines through the voice output four wire and PTT voice signal detection module. The technical implementation success rate of voice detection in complex environment, ensures the voice and PTI＂ reliability of signal transmission. |
