1. Learning equipment comprising: dialog means for obtaining a name of a target object through dialog; a plurality of recognition means for detecting a plurality of characteristic data of said target object, and for recognizing the target object based on a detection result and corresponding characteristic data of a known object; storage means for storing associative information relating recognition results of said recognition means for a name of said known object; judgment means for judging based on the name of said target object obtained by said dialog means, recognition results of said recognition means for said target object, and said associative information stored in said storage means, whether or not said target object is a new object, wherein the dialog means determines a content of the dialog with a user based on a face recognition result obtained by one of the plurality of recognition means, wherein when the recognition means recognizes a name of the user through a morphological characteristic of a face of the user, the dialog means obtains a confirmation of the recognized name from the user through dialog, wherein when the recognition means fails to recognize a name of the user through a morphological characteristic of a face of the user, the dialog means asks the user for the user's name through dialog, wherein the associative information relates the name to at least a sound identifier and a face identifier of the target object, and wherein when the name of said target object obtained by the dialog means is different than a name obtained by the recognition results, the judgment means determines that target object is a new object; and control means for storing said plurality of characteristic data on said target object in corresponding said recognition means and storing associative information on the target object in said storage means when said judgment means judges that said target object is a new object.
