摘　　要：为实现普通电话语音信号的数字化,以较低的硬件成本实现语音的网络传输,将分组语音技术与计算机处理技术、因特网技术相结合,组建了一套单片机控制系统.该系统利用单片机通过以太网进行分组语音数据包的发送与接收.实验运行结果表明,该系统不但具有较高的语音通话质量,而且能够提供更多的电信增值服务业务,具有较高的应用价值.In order to digitize the voice signal from common telephone and transfer the voice data over Ethernet with a low hardware cost, a MCU control system by combining the voice-overpackage technology with the computer process technology and Internet technology is established. MCU sends and receives voice data package over Ethernet. Experimental results indicate that the system not only has high voice communication quality, but also provides more telecom value-added services. It is very valuable in practice.
