A MBE语音压缩算法在机车语音记录仪中的应用

A MBE Algorithm and Its Application in Locomotive Voice Recording System

IMBE和AMBE都是基于MBE技术的低比特率、高质量语音压缩算法 ,其优越的性能已得到国际公认 ,并植于DVS公司的AMBE2 0 0 0语音压缩芯片内。以AMBE2 0 0 0压缩芯片为核心实现的机车固态语音记录仪 ,具有智能化、全电子、记录时间长、可靠性高的特点 ,是保证铁路行车安全的重要设备 。

IMBE(Improved Multi-Band Excitation)and AMBE(Advanced Multi-Band Excitation)both based on the proprietary MBE(Multi-Band Excitation)speech compression algoritym are internationally recognized as the best speech compression algorithms in the world ,and AMBE has been built in DVSI’s AMBE2000 speech compression vocoder The locomotive voice compression recorder based on AMBE2000 chip possesses the characteristics of intelligibility,full-electronics,long-time recording and high reliability The recorder,which has been gradually equipped throughout the railway system,is an important equipment by which railway transportation safety can be realized
