An object recognition system is applicable to practical use, and utilizes image information besides speech information to improve recognition accuracy. The object recognition system comprises a speech recognition unit to determine candidates for a result of speech recognition on input speech and their likelihoods, and an image model generation unit to generate image models of a predetermined number of the candidates having the highest likelihoods. The system further comprises an image likelihood calculation unit to calculate image likelihoods of input images based on the image models, and an object recognition unit to perform object recognition using the image likelihoods. At the time of generating the image model of the candidate, the image model generation unit first searches an image model database, and, when the image model of the candidate is not found in the database, the image model generation unit generates said image model from image information on the web.

Object recognition system and an object recognition method

An apparatus is provided for classifying targets into a known-object group and an unknown-object group. The apparatus includes a speech/image data storage unit configured to store a spoken sound of a name of an object and an image of the object; a unit configured to calculate a speech confidence level of a speech for the name of the object with reference to a spoken sound of a name of a known object; a unit configured to calculate an image confidence level of an image of an object with respect to an image of a known object; and a unit configured to compare an evaluation value, which is obtained by combining the speech confidence level and image confidence level, with a threshold value, and classify a target object into an object group determined according to whether the spoken sound of the name and the image are known or unknown.
