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。
Objective To explore the change rule of speech features of speech generated by simulated head-lying ambulatory simulated weightlessness. Methods Subjects were 6 healthy male youth, head to head low - 6 ° simulated voice recording under the conditions of weight loss and changes in the law. Results Compared with the control group, the duration of speech increased with simulated weightlessness. The average energy was significantly decreased with a significant reduction in the fundamental frequency and a significant difference (P <0.05). Conclusion Simulated weightlessness has a certain impact on human speech features, and some speech features have significant effects.
