To improve correct answer accuracy of voice recognition and intention understanding processing together, by performing optimum voice recognition processing and relearning of intention understanding processing properly based on user's response.SOLUTION: The growth type interactive device includes a voice recognition unit based on the result of voice learning, an intention understanding unit based on the result learned from the intention understanding learning data, an extended intention understanding unit based on learned results from an extended intention understanding learning data obtained by expanding the intention understanding learning data, a user reaction identification unit which determines whether the reaction of the user in the voice and vision is positive or negative, an error cause analysis unit which determines whether there is an error in the voice recognition processing or an intention understanding processing based on the determination result whether the user reaction is positive or negative, and a relearning determination unit which instructs, according to the determination of the error cause analysis unit, an intention understanding learning processing from a voice recognition learning processing, intention understanding learning data, or extended intention understanding learning data.SELECTED DRAWING: Figure 6
