Title Effects of synthesized voice warning parameters on perceived urgency
Bibliographic information 1999, Vol.5, No.1, p.73-95. Illus. 31 ref.
Abstract The effects of synthesized voice warning parameters on perceived urgency were examined in order to build a detailed and usable description of the relation between the parameters of synthesized voice warnings and perceived urgency. Ten native and 10 non-native English speakers participated in 4 experiments to evaluate and quantify the effects of the voice parameters. The results showed that speech rate, average fundamental frequency (F0 ), voice type simulated (male or female), and the fundamental frequency contour have clear effects on the perceived urgency of synthesized voice warnings. Significant differences in the perceived urgency of average F0 and F0 contour types between native and non-native English speakers were found. Implications of the results for the design and improvement of synthesized voice warnings are discussed.
