VOICE RECOGNITION APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. A voice recognition apparatus comprising a processor comprising:
- an extractor configured to extract utterance elements from an uttered voice of a user;
a lexico-semantic pattern (LSP) converter configured to convert the extracted utterance elements into LSP formats; and
a controller configured to determine whether an utterance element related to an Out Of Vocabulary (OOV) exists among the utterance elements converted into the LSP formats with reference to vocabulary list information comprising pre-registered vocabularies, and to determine an Out Of Domain (OOD) area in which it is impossible to provide response information in response to the uttered voice, in response to determining that the utterance element related to the OOV exists.

Abstract
A voice recognition apparatus includes: an extractor configured to extract utterance elements from a user'"'"'s uttered voice; an LSP converter configured to convert the extracted utterance elements into LSP formats; and a controller configured to determine whether an utterance element related to an OOV exists among the utterance elements converted into the LSP formats with reference to vocabulary list information including pre-registered vocabularies, and to determine an OOD area in which it is impossible to provide response information in response to the uttered voice, in response to determining that the utterance element related to the OOV exists. Accordingly, the voice recognition apparatus provides appropriate response information according to a user'"'"'s intent by considering a variety of utterances and possibilities regarding a user'"'"'s uttered voice.

15. A voice recognition apparatus comprising:
-
a display; and a processor which is configured to determine whether voice of a user contains words which are non-matchable to content providing domains by; extracting utterance elements from the voice; converting the extracted utterance elements into lexico-semantic pattern (LSP) formats; determining a presence of an Out Of Vocabulary (OOV) utterance element, among the converted utterance elements, based on pre-registered vocabularies; determining that the voice contains an Out Of Domain (OOD) area which is non-matchable with the content providing domains, in response to the presence of the OOV utterance element; and providing a message informing the user of the non-matchable word present in the voice of the user. - View Dependent Claims (16, 17, 18)
