APPARATUS FOR SPEECH RECOGNITION AND METHOD THEREOF

摘要

PURPOSE: A voice recognition apparatus and voice recognition method are provided to improve the performance of voice recognition by supplementing a language model which includes qualified data. CONSTITUTION: A first voice recognition unit(110) detects first word lattice information through continous word recognition about input voice. A second word lattice information detecting unit(120) detects second word lattice information. A merging unit(130) creates integrated lattice information through the first word lattice information and the second word lattice information. A second voice recognition unit(140) creates a sentence about the input voice using second voice recognition through the integrated lattice information.
