| 摘 要： | 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。

| Abstract: | Objective To study changes of phonetic features of mandarin speech when the talker is in stressed environment of spaceflight.Methods The mandarin speech database was established from volunteers speech in 72 h psychological isolation & sleep deprivation experiment,60 d head-down-tilt bed-rest experiment and 60 d sealed module experiment.The phonetic features were fundamental frequency,syllable duration and short-term energy of speech.Results In above three kinds of stressed environments,the changes of fundam... |
