US WEST Advanced Technologies conducted an experiment using the "Wizard-of-Oz" paradigm. We compared a simulated speech recognition interface ("wizard") for a basic voice mail application to functionally similar touch-tone and operator assisted versions. This poster abstract highlights the results of this experiment, focussing on performance times and errors, the perceived ease of use, and a description of the linguistic characteristics of users' utterances. The results are interpreted to be in favor of applying speech recognition technology to user interfaces.
