APPARATUS AND METHOD USING TWO PHASE UTTERANCE VERIFICATION ARCHITECTURE FOR COMPUTATION SPEED IMPROVEMENT OF N-BEST RECOGNITION WORD

摘要

PURPOSE: A voice recognition apparatus and method having two-step utterance verification structure for reducing the complexity of N-best recognized word calculation are provided to induce the re-utterance of a user or notify the user of an utterance error. CONSTITUTION: Using a first model, a voice recognition module(130) recognizes the voice of input voice data. The voice recognition module outputs a first N-best word list. An utterance verification module(140) creates a second N-best word list. Using a second model, the utterance verification module creates a final N-best word list from the second N-best word list.
