The present invention relates to a method and a system for recognizing a voice using three-dimensional geometry information. The voice recognition system comprises a learning module and a recognizing module. The learning module generates a recognition unit using three-dimensional geometry information for study and three-dimensional features for study extracted from the information. The recognizing module applies the three-dimensional geometry information acquired from a physical target related or belonged to a voice or three-dimensional features extracted from the geometry information to the recognition unit, and conducts voice recognition. The method and the system for recognizing a voice according to the present invention, recognizes a voice using three-dimensional geometry information on lips, a part around the lips, or one or more arbitrary regions of a human body in speech. Also, final voice recognition is conducted by combining two-dimensional features and sound features, and three-dimensional features and sound features in speech, and by combining recognition result of the two-dimensional features or sound features, or recognition result of the three-dimensional geometry information or three-dimensional features in speech. Therefore, the accuracy of voice recognition is improved. |
