합성음성 경보의 주관적 위급도에 관한 연구

This paper presents an experimental study of the relationship between sound parameters of synthesized voice warning and perceived(psychoacoustic) urgency. Eighteen subjects participated in two experimental sessions to evaluate and quqntify the effects of the voice parameters. Experiments showed that speech rate, fundamental frequency and voice types have clear and consistent effect on perceived urgency. The results of these experiments can be applied to the improvement of existing auditory warning systems and the design of new systems.
