Design of embedded voice communication system

Voice communication is the most basic and important means to people directly exchange. Meanwhile, with the development of embedded systems, where the mobile phones, televisions, set-top boxes and other home electronics and communication products and even electric transport control core are all closely related to embedded systems. This paper describes the design and implementation of a multi-way voice communication system with the internet protocol of UDP, using S3C2440A as the control core and other Peripheral Circuits realize the voice processing and transition functions. Experiments show that the system not only can meet the fast processing, but also meet the requirements of small and portable.
