摘要
为解决语音通信过程中存储空间和信号带宽的限制,实现高压缩率语音传输,设计了一种低速率语音编码模块。该模块由语音编解码专用芯片MA24126-P1,音频codec芯片TLV320AIC23,单片机以及相关接口电路构成,可实现600bps,1200bps以及2400bps三种速率下的语音编解码处理。经测试,经该模块编解码后的语音信号具有较高的清晰度、可懂度、自然度。
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.
