2. Description of the Related Art
Because display apparatuses have been capable of recognizing user's voice, display apparatuses have been capable of recognizing user's speech voice to provide a voice recognition result intended by users or perform a control command.
In particular, the most universal method related to a voice conversation service that provides the voice recognition result intended by users is a keyword recognition method that performs a conversation between users and display apparatuses through a search engine. Such a keyword recognition method refers to display apparatuses that perform a search related to a core keyword based on speech voice related to the core keyword and provide a search result. However, such a method provides numerous search results related to the speech voice for the core keyword, and thus users experience inconvenience by having to search for desired information from numerous search results.
Another method is a sentence recognition method, where display apparatuses analyze speech voice related to a question sentence of a user to determine a user's speech intention, perform a search based on the determined speech intention, and provide an answer result according to the search.
Such a sentence recognition method is advantageous compared to the keyword recognition method described above in that the sentence recognition method provides an answer result closer to the user's speech intention. However, when a sentence speech appropriate to a preset pattern is not input, or noise occurs in the sentence speech due to an external environment, such a sentence recognition method does not perform correct voice recognition on the sentence speech of a user.
