Japanese Unexamined Patent Publication No. 2006-20907

In a system that interacts with a user according to the rule of uttering a word having the ending character of the word uttered by the other party at the beginning, it is necessary to correctly recognize the word input by the other user. For example, when a word input by a user is a text input by a character other than "kana" as exemplified by a kanji, and the word can be associated with multiple readings. , The system cannot determine whether or not a word has been input according to the rules, and cannot output a word according to the input word. In addition, when a word is input by voice input, erroneous recognition in the voice recognition process may occur even if the user utters the word according to the rule, and the system is uttered by the user. Words may not be recognized correctly.

Therefore, the present invention has been made in view of the above problems, and is a word uttered by the user in a system for interacting with the user according to the rule of uttering a word having the ending character of the word uttered by the other party at the beginning of the word. The purpose is to improve the possibility of correctly recognizing.

In order to solve the above problem, the dialogue system according to one form of the present invention is a dialogue system that interacts with a user according to a rule that a word having a character at the end of a word uttered by the other party is uttered at the beginning of the word. An acquisition unit that acquires a second word that is a word input by the user according to the first word issued by the system, and a character that constitutes the second word based on the character at the end of the first word. It includes a determination unit that determines a column, and an output unit that outputs a third word that is a word according to a rule according to the character string of the second word determined by the determination unit.

According to the above form, if the second word is a word uttered according to a rule, the second word constitutes the second word in view of having the ending of the first word at the beginning of the word. Since the character string is determined based on the character at the end of the first word, it constitutes the second word even if it is difficult to identify it due to the input mode of the second word. The character string can be recognized correctly.

It is possible to improve the possibility of correctly recognizing a word uttered by the user in a system that interacts with the user according to the rule of uttering a word having the ending character of the word uttered by the other party at the beginning of the word.
