Apparatus for multi domain sound communication and method for multi domain sound communication using the same

PURPOSE: A multi-domain voice conversation apparatus and a multi-domain voice conversation method using thereof are provided to select the final domain, which is able to generate the optimal system conversation corresponding to the user conversation, thereby implementing natural conversation between the user multi-domain voice conversation apparatuses. CONSTITUTION: A conversation analysis unit (150) extracts the corresponding features from the user conversation. A candidate domain extraction unit (160) calculates suitability of each multi-domain of the user conversation. The candidate domain extraction unit aligns the multi-domain based on the suitability, and extracts the candidate domains. A final domain determiner (170) determines the final domain by the selection of a first candidate domain among the candidate domains. A multi-domain unit (190) enables the final domain to generate the system conversation corresponding to the user conversation.
