| Abstract: | A 1200/2400bps full duplex modified vocoder based on the multi band excitation(MBE) speech model is presented.It has been used in many communication systems.Diagnostic Rhyme Test(DRT) results show that the speech distinctness at 1200bps and at 2400bps is 91.75 and 92.67 respectively.This paper focuses on the hardware architecture and algorithm implementation. |
