为研究噪声、振动复合因素对汉语发音的影响，对汉语单音节的语音特征变化进行了研究。本研究设计了获取噪声与振动复合因素下发音的实验，实验分噪声与振动复合因素、单独噪声、单独振动、正常对照四种条件，并建立了一套语音处理硬件系统，编制了语音分析程序和显著性检验程序。结果表明，噪声与振动复合因素下，汉语语音的基频、能量、时长与对照组和单因素组比较都有显著性增加。这一结果对于航天中语音识别系统的设计具有一定的参考价值。
In order to study the influence of noise and vibration compounding on Chinese pronunciation, the change of speech features of Chinese monosyllables has been studied. This study designed to obtain noise and vibration under the combination of pronunciation of the experiment, the sub-noise and vibration components of the experiment, the individual noise, vibration alone, the normal control of four conditions, and established a set of voice processing hardware system, the preparation of the voice analysis program And significance test procedure. The results show that under the combination of noise and vibration, the fundamental frequency, energy and duration of Chinese speech significantly increased compared with the control group and the univariate group. This result has certain reference value for the design of speech recognition system in aerospace.
