摘要：本文讨论了最近完成的ITT VRS-1290说话人相关连续语音识别系统在NASA刘易斯研究中心OV-10 A飞机上的飞行试验结果。13名飞行员使用M-162吊杆式麦克风在地面和1g和3g飞行条件下测试了54个单词的词汇。数字录音带（DAT）记录了受试者所说的短语和周围的背景噪音。在某些飞行条件下，OV-10A后驾驶舱的噪音水平超过115 dB，这使其成为测试ITT系统鲁棒性的理想平台。在飞行试验计划的早期阶段，DAT记录是优化ITT系统性能的一个关键因素。13名飞行员的平均单词准确率在1g条件下为98.3%，在3g条件下为97.3%。还讨论了未来的测试计划，使用DAT生成的数据库与其他语音系统。
Abstract : This paper discusses the results of a recently completed flight test of an ITT VRS-1290 speaker dependent, continuous speech recognition system onboard a NASA Lewis Research Center OV-10A aircraft. A 54-word vocabulary was tested with thirteen pilots using an M-162 boom-mounted microphone on the ground and under 1g and 3g flight conditions. Digital audio tape (DAT) recordings were made of both the subjects spoken phrases and the ambient background noise. Under some flight conditions, noise levels in the rear cockpit of the OV-10A were in excess of 115 dB which made it an ideal platform for testing the robustness of the ITT system. The DAT recordings were a critical element in optimizing the performance of the ITT system during the early stages of the flight test program. Average word accuracy for the thirteen pilots was 98.3% in the 1g condition and 97.3% in the 3g condition. Also discussed are plans for future testing using the DAT generated database with other speech systems.
