Perceived Urgency of Voice Alarms in Emergency Evacuations
Effective and compelling warnings are critically needed in emergency evacuations, especially in large buildings or in facilities where occupants may be unfamiliar with the environment. Voice alarms have the potential to capture attention and direct occupants efficiently and effectively in an emergency. To inform the design of voice alarms, most previous studies have examined the perceived urgency of individual words in a warning signal. However, very few studies have been conducted on voice alarms that present entire sentences and are broadcast to a large group of people during emergency evacuations. The present study investigated how to optimize the acoustic (speech rate, noise level, SNR, gender of speaker) and semantic parameters of Chinese synthesized speech warnings to ensure that occupants react to an emergency promptly and appropriately.
