This study investigated the effects of speaker gender and sound pressure level (SPL) of voice alarm messages on the pre-evacuation behaviour of building occupants, with the aim of providing foundational data for human-centred voice alarm signal design. A series of experiments were conducted in a fully anechoic chamber, in which voice alarm messages delivered by male and female speakers were presented at SPLs of 80, 85, 90, and 95 dB(A). Occupant responses were recorded and subsequently quantified through video analysis, whereby observed behaviours were categorised into three distinct phases: perception, interpretation, and action. The results indicated that, under the male voice condition, occupants predominantly exhibited no discernible response or engaged in information-seeking behaviour at SPLs of 80-85 dB(A), with the initiation of evacuation movement observed only at SPLs of 90 dB(A) and above. In contrast, under the female voice condition, attentive listening, information-seeking behaviour, and the initiation of evacuation movement were observed from 80 dB(A), demonstrating a behavioural prompting effect at comparatively lower SPLs. At equivalent SPLs, the female voice condition was associated with a lower proportion of non-response and a tendency towards more rapid initiation of evacuation movement compared with the male voice condition. These findings may contribute to the evidence base for the design of voice alarm signals and the refinement of associated standards that account for occupant recognition and behavioural response characteristics.
