Abstract
ARM is a 16/32-bit low-power and high-performance microprocessor.ARM can run Windows CE which is a 32-bit real-time multitasking operating system.Embedded system based on ARM / Windows CE has been widely applied in many different areas.This paper introduced the application of ARM-based embedded system in network speech communications,and about how to build Windows CE development platform and design applied software with Windows CE embedded operating system based on ARM11 microprocessor.This design used DM9000 for network signal transmission,and used WM9714 for speech signal acquisition and encoding.The network voice communication system was designed using ARM11 embedded system as the terminal,and the user interface is friendly.
