| 摘 要： | 目的探讨头低位卧床模拟失重作用下生成语音的语音特征的变化规律。方法被试者为 6名健康男性青年 ,头低位 - 6°模拟失重条件下记录语音特征及变化规律。结果与对照组相比 ,模拟失重作用下语音的时长有一定增加 ;平均能量明显降低 ,结果非常显著 ;基频有一定降低 ,并有显著性差异 (P <0 .0 5)。结论模拟失重对人的语音特征产生一定影响 ,某些语音特征的影响具有显著性。

| Abstract: | 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. |
