N2 - This study addresses the importance of encouraging effective interaction of users with information systems. We examined the interaction between users and a spoken language interface through a user-centered Wizard of Oz experiment, in which the user behavior of a spoken language search interface which allows only spoken query and touch behavior, was compared with a generic keyboard baseline interface. Forty-eight participants joined the experiment, with each searching on 12 different topics of three types. Results showed that using the spoken interface resulted in significantly less interaction measured by the number of iterations, number of viewed webpages, and number of clicks/touches, than using the baseline interface. In terms of query length, participants using the spoken interface issued significantly longer queries than those using the baseline interface. Results also indicated that participants spent significantly more time in completing tasks, dwelling on each document, and making decisions on each document using the spoken language interface than using the baseline interface. Design criteria and implications for spoken language systems were discussed.
