11. A method of performing voice recognition for providing response information corresponding to a user's utterance voice in a dialogue type voice recognition apparatus, implemented by at least one hardware processor, the method comprising: converting a user's utterance voice signal into text; extracting a first utterance element representing a user action and a second utterance element representing an object from the text of the user's utterance voice signal; detecting an expansion domain, being related to the extracted first utterance element and second utterance element, in a hierarchical domain model, when a user action script, comprising a main action corresponding to the first utterance element and a component slot corresponding to the second utterance element, is included in the expansion domain, wherein the hierarchical domain model comprises a plurality of candidate domains of a lowermost concept and the expansion domain, including at least two candidate domains, of an uppermost concept; detecting at least one candidate domain related to the detected expansion domain when the user action script is included in the candidate domain; determining the at least one candidate domain related to the detected expansion domain as a final domain; detecting a candidate domain, when the user action script is included in the candidate domain and the expansion domain is not detected; transmitting information regarding the first and second utterance elements and information regarding the determined final domain as a result of the voice recognition to an external apparatus; and receiving response information related to the first and second utterance elements within the determined final domain from the external apparatus.
13. The method according to claim 11 , wherein the detecting the expansion domain comprises: using a multi classifier to detect a subordinate candidate domain related to the detected expansion domain, where the main action corresponding to the first utterance element and the component slot corresponding to the extracted second utterance element are matched to each other is detected, and when the expansion domain is not detected, the detecting the expansion domain incorporates using a multi-classifier to detect a candidate domain, where the main action corresponding to the first utterance element and the component slot corresponding to the second utterance element are matched to each other.
