APPARATUS AND METHOD FOR DETECTING TOPIC OF VOICE RECOGNITION SYSTEM

摘要

PURPOSE: An apparatus and a method for detecting a topic of a voice recognition system are provided to increase discrimination by increasing the number of components of a basic analysis unit, thereby reducing an error of topic detection. CONSTITUTION: If voice data is inputted to an apparatus for detecting a topic, a phoneme recognizer(100) recognizes phonemes from the input voice data. A key string detector(110) separately packs the recognized phonemes for integrating the phonemes by the base analysis unit. A topic comparator(120) calculates the probability of the basic analysis unit that the basic analysis unit appears from topic data of trained data preliminarily memorized, and judges appropriateness of each topic by the probability of appearance for granting a score. A topic detector(130) detects topics more than a preliminarily set threshold in the score-granted topics.
