Driving with a Speech Interaction System: Effect of Personality on Performance and Attitude of Driver

摘要

Personality has a huge effect on how we communicate and interact with others. This study is one in a series of three that investigates how a speech based in-car system matched with dominant and submissive drivers affects performance and attitude drivers. The study was conducted with 30 participants at Linkoping University in Sweden. Data show that using a voice that combines feature from submissive and dominant speech patterns work well for both dominant and submissive drivers. The voice showed the same performance gain as when matching car voice personality with personality of driver, without the negative attitude ratings associated with the submissive car voice found in previous studies. Drivers assessment of the car system show that even though both dominant and submissive drivers find the system helpful, dominant drivers find the system more annoying and more likely to turn the system off. Design implications of in-vehicle systems are discussed.
