目的研究模拟航天应激环境对发音人语音特征的影响。方法在72h心理隔绝及睡眠剥夺实验,密闭舱60d试验,以及头低位60d模拟失重试验中,录制受试者的语音,并进行分析。结果在3种应激环境下,烦躁情绪的出现与基频的变化具有一定的一致性,音节时长、短时能量的变化与时间节点有关。结论根据特征参数改变规律,可为进一步的应激语音情绪识别奠定理论基础。
Objective To study the effect of simulating aerospace stress environment on phonetic characteristics of speaker. Methods During the 72h psychological isolation and sleep deprivation test, 60 days closed chamber test and 60 days head-down simulated weightlessness test, the subjects’ voices were recorded and analyzed. Results The frequency of irritability was consistent with the change of fundamental frequency under the three stress conditions. The change of syllable duration and short-term energy was related to the time node. Conclusion According to the change rule of the characteristic parameters, it can lay a theoretical foundation for further emotional speech recognition.
