为探讨航天器在噪声背景下汉语语音告警适宜参数的选择，采用自行建立的“语音报警工效学模拟与分析系统”，对４０名视、听正常的健康男性，进行了双重作业下的载人航天器报警用语听觉反应时实验以及主告警音适宜时长主观评定实验，并从听觉反应时、认知特性以及报警对作业负荷的影响等几方面对航天器汉语语音告警适宜参数的选择进行了分析。结果显示：主告警音时长０．３５～０．５５ｓ、主间隔０．１５～０．３５ｓ、语速４～６字／ｓ、句间隔０．２～０．４ｓ较适宜；同时心率及其变异性分析表明，选用上述参数的报警语音不会增加作业人员的工作负荷。此结果可为载人航天器语音报警系统的设计提供参考标准。
In order to explore the choice of suitable parameters of Chinese voice warning for spacecraft under the background of noise, a self-built “voice alarm ergonomics simulation and analysis system” was used to test the effect of manned persons Spacecraft alarm language auditory response time experiment and the main warning sound suitable duration subjective assessment experiment, and from the auditory response, cognitive characteristics and the impact of the alarm on the workload and other aspects of the appropriate choice of Chinese voice siren parameters were analyzed . The results showed that: the main alarm sound duration of 0.35 ~ 0.55s, the main interval of 0.15 ~ 0.35s, speech rate of 4 to 6 words / s, sentence interval of 0.2 ~ 0.4s more appropriate; the same time, heart rate and its The analysis of variability shows that using the above parameters of the alarm voice does not increase the workload of the workers. This result can provide a reference standard for the design of manned spacecraft voice alarm system.
