Abstract

Live Search for Mobile is a cellphone application that allows

users to interact with web-based information portals. Currently

the implementation is focused on information related

to local businesses: their phone numbers and addresses, directions,

reviews, maps of the surrounding area, and traffic. This

paper describes a speech-recognition interface which was recently

developed for the application, which allows the users

to interact by voice. The paper presents the overall architecture,

the user interface, the design and implementation of

the speech recognition grammars, and initial performance results

indicating that for sentence level utterance recognition

we achieve 60 to 65% of human capability.
