摘　　要：将介绍一种基于AMBE- 10 0 0的高质量语音系统,该系统使用了DVSI公司开发的AMBE语音芯片,可以在低速率下保持声音自然、语音清晰,并且在选择语音速率和误码率中提供了很高的灵活性,此外还具有低成本、低功耗等优点。因此,该系统具有广泛的应用前景,可以应用于诸如安全通信、话音多路传输、卫星通讯、多媒体应用、蜂窝电话等多种语音处理的场合。This article introduces a system with superior voice quality based on AMBE1000.The system circuit makes use of DVSI′s AMBE1000 voice chip.It maintains natural voice quality and speech intelligibility at low data rates and provides a high degree flexibility in selecting the speech and Forward Error Correction(FEC) data rates.Furthermore,it′s a low cost,low power circuit. Thus the system has widely potential application at voice processing aspects, such as secure communications, voice multiplexing, satellite communications, multimedia applications, cellular telephony.
