Study of Speech Information System

某型进口运输机语言信息系统采用的电机卷带播放磁带存在语音录制更改困难、信息条目有限、音质逐渐变差、磁带磁头需定期清洁更换、故障率较高等突出问题;利用单片机控制技术和半导体语音存贮技术对语言信息系统进行重新设计,阐述了系统电路设计原理和软件流程,具有操纵控制自动化程度高,成本低等优点,并且达到了无转动部件和无机械触点,满足机载设备要求,具有良好的军事和经济效益。

The speech information system of an import aerotransport has the problems of difficult speech recording, smaller information items, bad speech quality, magnetic tape and head being cleaned and replaced periodically, high trouble rate, etc. A new design of the system has been given with SCM control technique and semiconductor speech storage technique. The designing principle of the system circuits and software flow chart are explained. The system has characteristics of highly auto controlling, low costs, no rotating parts and no mechanical joints. It has good military and business benefits.
