<P>PROBLEM TO BE SOLVED: To provide a sound dialogue device which is robust in meaning processing system with respect to speaker's rephrase, fumble for the correct words or the like, has a high capability of understanding of meaning, and whose calculation cost is low. <P>SOLUTION: In a word extraction part (step 320) of a meaning understanding part, a Japanese character string, including false recognition 'NakakujyaNakakujyatte, Chigusakunoresutorande' is converted into a word string 'Nakaku/jya/Nakaku/tte/, /Chigusaku/no/resutoran/de'. In a word category identification part (step 340), an expected slot value and a possible words (Nakaku, nakaku, Chigusaku, resutoran) are picked up from the above word string and the category is identified. Then, in a word selection part (step 360), a slot value to be actually adopted is determined. For instance, from three values (Nakaku, Nakaku, and Chigusaku) corresponding to the address slots, 'Chigusaku', the last one the speaker vocalized is decided to the slot value to be adopted. Thus, a meaning processing with robust, high precision, high speed, and low cost is realized. <P>COPYRIGHT: (C)2003,JPO |
