通信系统试飞中语音清晰度判定研究

描述了飞机通信系统试飞中语音清晰度的概念以及"SINPO"等级划分。介绍了国内目前在试飞中语音清晰度判定的方法及其不足之处,通过对国外"同韵词表格法"的分析和研究,在此基础上提出了适合我国通信系统试飞的"近音词表格法"。该方法用定量计算的结果来判定语音清晰度的等级进而准确判定通信系统的功能符合性,可为从事飞机通信系统试飞领域的人员提供一种新的思路和方法。

Evaluation of Speech Intelligibility in Flight Test of Communication System

This paper described the concept of speech intelligibility in the flight test of communication system and“SINPO” rating. The common methods of evaluating the speech intelligibility in flight test and the disadvantages were introduced. Based on the research and analysis on the foreign“Rhyme List”method, the revised“Rhyme List”adopted to the flight test of our country＇s communication system is established. This method defined the rank of speech intelligi-bility and judged the function compliance of the communication system accurately by quantitative calculation . It could provide a new kind of method for the people engaged in the field of communication system＇s flight test.
