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.
