Effects of synthesized voice warning parameters on perceived urgency.

چکیده
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 [F(0)], voice type, and fundamental frequency contour have clear effects on the perceived urgency of synthesized voice warnings. The effects of quantitative parameters on perceived urgency were scaled using an application of Stevens's power law (1957). In addition, the results showed significant differences in the perceived urgency of average F(0) and F(0) contour types between native and non-native English speakers. Implications of the results for the design and improvement of synthesized voice warnings are discussed.

Alerts for In-Vehicle Information Systems: Annoyance, Urgency, and Appropriateness
OBJECTIVE This study assesses the influence of the auditory characteristics of alerts on perceived urgency and annoyance and whether these perceptions depend on the context in which the alert is received. BACKGROUND Alert parameters systematically affect perceived urgency, and mapping the urgency of a situation to the perceived urgency of an alert is a useful design consideration. Annoyance a...
متن کاملAcoustic and Semantic Warning Parameters Impact Vehicle Crash Rates
Auditory Collision Avoidance Systems (CASs) are increasingly common in the modern automobile. Verbal warnings are increasingly being used in aviation and medical environments; but, they have received considerably less attention in the driving research community. Here, I discuss a recent series of investigations aimed at examining the impact of acoustic and semantic warning parameters on crash r...

متن کاملEvaluating warning sound urgency with reaction times.
It is well-established that subjective judgments of perceived urgency of alarm sounds can be affected by acoustic parameters. In this study, the authors investigated an objective measurement, the reaction time (RT), to test the effectiveness of temporal parameters of sounds in the context of warning sounds. Three experiments were performed using a RT paradigm, with two different concurrent visu...
