In order to solve the limitation of storage space and signal bandwidth in speech communication,a low rate speech coding module is designed to realize high compression rate voice transmission. The module consists of voice codec chip MA24126-P1,audio codec chip TLV320AIC23,mictocontroller and related interface circuit,can achieve 600bps,1200bps and 2400bps at three rates of voice. After testing,the speech signal afer the module is compiled and decoded has high definition,intelligibility and naturalness.
