| Abstract: | With the sharply enlarging of message transmission, band resource is becoming more costful. It is the hotspot in research how to use bandwidth properly and save resource. This article introduces the compressing and coding methods of voice signal, and chooses a compressing and coding method which is suitable for narrowband voice communication. It also designs a voice linker that can be used to connect with voice terminal such as telephone etc. |
