为探讨汉语语音报警中预警声长度、预警间隔、句间隔、语句字数等对作业人员认知特性的影响，采集符合人认知特性的最佳设计参数，对２０名听力正常的健康男性进行了汉语语音报警参数认知特性评价实验，结合我们对汉语语音报警感知－反应时间的研究，确定了符合航天工效学及人认知心理特性的汉语语音告警最佳参数：预警音时长０．３５～０．５５ｓ、预警间隔０．３～０．４ｓ、句间隔０．３～０．４ｓ、语句字数≤７字。此研究结果可为载人航天器语音报警系统的设计和评价提供参考标准
In order to explore the influence of the length of warning sound, warning interval, sentence interval and word number on the cognition of workers in Chinese phonetic alarm, the best design parameters of human cognitive characteristics were collected and 20 healthy normal men Based on our research on the perception of Chinese voice alarm - response time, the best parameters of Chinese voice alarm that meet aerospace ergonomics and human cognitive psychology characteristics were determined: the duration of the warning sound is 0.35 ~ 0.55s, warning interval 0.3 ~ 0.4s, interval 0.3 ~ 0.4s, the number of words ≤ 7 words. The results of this study can provide a reference for the design and evaluation of manned spacecraft voice alarm system
