In the storage device 15, a group of words used and understood by a mermaid "Seaman" in an application is registered as a "dictionary". FIG. 3 is a diagram showing the structure of this dictionary, which is registered for each category.

For example, in item number 1, a question "You are a man" of a mermaid "Seaman" and answers a and b to the question are registered. In item number 2, a question "Your age" of the mermaid "Seaman" and answers a, b,... To the question are registered. Hereinafter, as shown in the figure, the question of the mermaid "Seaman" and its answer are registered as a multi-word dictionary.

The processing operation of the system having the above configuration will be described below. FIG. 4 is a flowchart for explaining the operation of this embodiment. First, a recognition candidate group corresponding to a question is set in a recognition engine (step (hereinafter, referred to as ST) 1). FIG. 5 is an example of a recognition candidate group set at this time, for example. This set of recognition candidate groups is the same as that of FIG.
Since the item to which the mermaid "Seaman" asks a question is known in advance as shown in FIG.

Next, when there is a question from the mermaid "Seaman" (YES in ST2), the process waits for a voice response from the user (ST3). For example, if the question from the mermaid "Seaman" is item number 2 shown in FIG. 3, the user is asked "You are old." In response to this question, the user answers his or her age to the microphone 20a as “〇〇” (S
T3 is YES).

For example, when answering "27 years old", the mermaid "Seaman" presents the candidate output by the recognition engine to the user and confirms it (ST4). For example, the mermaid "Seaman" presents "You are 17 years old" to prompt the user to confirm (see FIG. 6).

Next, the user answers the question of the mermaid "Seaman" (ST5). The mermaid "Seaman" determines whether the answer is a negative answer (ST
6) If the answer is affirmative (NO in ST6), it is determined as an answer to the question (ST7).

On the other hand, if the answer is a negative answer (YES in ST6), another response is read from the recognition engine and presented to the user (ST8). For example, the mermaid "Seaman" presents "Are you 27 years old?" If the answer is negative, the previously presented candidate is deleted from the recognition candidate group (ST9). For example, in the above case, the candidate of “17 years old” is deleted.

Thereafter, the same processing is performed (ST2 to ST2).
8) For example, the mermaid "Seaman" asks a question by saying "I will listen again, but you are old" (see FIG. 7). If the answer to the question is negative, the above process is further continued, and the candidate presented next is also deleted from the recognition candidate group.

By performing processing as described above, when a conversation is performed with the mermaid "Seaman" while using the recognition engine, candidates rejected by the user are sequentially deleted, and finally an accurate answer is derived. be able to.
