本研究旨在探讨自然灾害语音预警的声学特性是否合适。三个声学参数（声音性别，语速和音高）进行了测试，以找出最佳的声学组合，提高感知的清晰度，可信度，和紧迫性的听众。100名以日语为母语的人听了一名男性和一名女性日语使用者的简短口头警告，音调正常，高20 Hz或低20 Hz;正常速度，快20%或慢20%。参与者将每个刺激分为1到5级。单效应分析结果表明：（1）女性声音的可信度和紧迫性较高;（2）正常音高在三个标准中的评分最高;（3）正常速度的评分最高，但速度越快，紧迫性越高。一项混合效应分析发现，女性声音、正常速度和更高音调的警告最能提高可信度和紧迫性。更快的sp.
The appropriateness of acoustic characteristics of speech warnings for natural disasters was examined in this study. Three acoustic parameters (voice gender, speech rate, and pitch) were tested in order to find out the best combination of the acoustics which enhances perceived intelligibility, credibility, and urgency by listeners. A hundred native speakers of Japanese listened to short verbal warnings spoken by a male and a female Japanese speaker with normal pitch, 20 Hz higher, or 20 Hz lower pitch; normal speed, 20% faster, or 20% slower speed. Participants rated each stimulus on 1-to-5-scale. A single effect analysis shows that 1) female voice was perceived with higher credibility and urgency; 2) normal pitch was rated best in the three criteria; and 3) normal speed was perceived best except that faster speed was perceived with higher urgency. A mixed effect analysis found that warnings with the combination of female voice, normal speed, and higher pitch most raised credibility and urgency. Faster sp...
