OBJECTIVE
To study the changes of phonetic features of Chinese speech during head-down bed-rest (HDBR) simulated weightlessness.
METHOD
During -6 degrees HDBR in 6 healthy subjects (20-30 years), acoustic-phonetic features were analyzed.
RESULT
The duration of utterance was slightly increase in the first two days, and recovered after the fourth day of HDBR; mean energy decreased along with time of bed rest, t-tests showed that the decrease in energy of utterances was very significant; a decrease in fundamental frequencies under HDBR was also significant.
CONCLUSION
There were certain changes in the acoustic phonetic features under HDBR, some of them were significant.
目的
研究头低位卧床休息（HDBR）模拟失重状态下汉语语音特征的变化。
方法
对6名健康受试者（20 - 30岁）在-6度头低位卧床休息期间的声学语音特征进行分析。
结果
发声时长在前两天略有增加，在头低位卧床休息第四天之后恢复；平均能量随卧床时间下降，t检验表明发声能量下降非常显著；头低位卧床休息状态下基频也显著下降。
结论
头低位卧床休息状态下声学语音特征存在一定变化，其中一些变化显著。
