摘要
在车内数字通信系统中,使用基于DSP嵌入式的以太局域网,实现车内语音和数据同传通信。笔者设计该系统时的重点是在语音数字处理,特别提出了一种自行设计的语音起止点判决方法———五点搜索法。
In digital communication system onboard of vehicle designed by us,an embedded LAN system based on DSP is used,speech and data are translated simultaneously.This paper stresses char-acteristics of digital speech processing in the system.A5-point searching method designed by myself is introduced especially for speech beginning-end point detection.[
