基于Direct Play API的语音通信系统实现

阐述了语音通信系统基于微软DirectPlayAPI开发通信软件,通过对网络结构和语音编码的详细分析和研究,成功地在多台飞行模拟器之间建立起独立的语音通信网络;为保证飞行模拟器声音仿真的完整性,语音通信计算机在完成语音数据交换的同时完成单机电台罗盘声、语音告警等声音的仿真。

A Speech Communication System Based on Direct Play API

By developing communication software which based on Direct Play API provided by Microsoft, analyzing and researching network structure and speech codec, an independent speech communication network which accords with radio control logic is built successfully among eight simulators. To ensure integrality of sound simulation in each simulator, speech communication computer is controlled by main flight program when finishing the exchange of speech data. Special sound such as radio box, needle sound and speech alarm in each simulator are realized by speech communication board.
