Abstract

A recognition portion obtains a recognition result based on a degree of similarity between a recognition object and lexicon entries included in a recognition lexicon. A task control portion instructs execution of a first task associated with the recognition result. A presentation control portion instructs presentation of one or a plurality of candidates associated with the recognition result and instructs a stop of the presentation of the candidate(s) when a time for which the candidate(s) has/have been presented has reached a predetermined time.
