SPEECH RECOGNITION DEVICE AND SPEECH RECOGNITION METHOD, DATA BASE FOR SPEECH RECOGNITION DEVICE AND CONSTRUCTING METHOD OF DATABASE FOR SPEECH RECOGNITION DEVICE

摘要

A speech recognition device comprises, a corpus processor which includes a refiner to classify collected corpora into domains corresponding to functions of the speech recognition device, and an extractor which extracts collected basic sentences based on functions of the speech recognition device with respect to the corpora in the domains, a database (DB) which stores therein the extracted basic sentences based on functions of the speech recognition device, a corpus receiver which receives a user's corpora, and a controller which compares a received basic sentence extracted by the extractor with collected basic sentences stored in the DB and determines the function intended by the user's corpora.
