DIALOGUE PROCESSING APPARATUS, A VEHICLE HAVING SAME, AND A DIALOGUE PROCESSING METHOD
First Claim
1. A dialogue processing apparatus comprising:
- a monitor configured to compare a level of an input signal with a reference level in real time and configured to determine that speech of a user is input when the level of the input signal is greater than the reference level;
a speech recognizer configured to output an utterance in the form of text by performing speech recognition on the input signal when it is determined that the speech is input;
a natural language processor configured to extract a domain and a keyword based on the utterance; and
a dialogue manager configured to determine whether a previous context is maintained based on the domain and the keyword.

Abstract
A dialogue processing apparatus and method monitor an intensity of an acoustic signal that is input in real time and determine that speech recognition has started, when the intensity of the input acoustic signal is equal to or greater than a reference value, allowing a user to start speech recognition by an utterance without an additional trigger. A vehicle can include the apparatus and method. The apparatus includes: a monitor to compare an input signal level with a reference level in real time and to determine that speech is input when the input signal level is greater than the reference level; a speech recognizer to output a text utterance by performing speech recognition on the input signal when it is determined that the speech is input; a natural language processor to extract a domain and a keyword based on the utterance; and a dialogue manager to determine whether a previous context is maintained based on the domain and the keyword.

11. A vehicle comprising:
-
a microphone configured to receive an input sound by being always opened and configured to convert the input sound into an electrical input signal; a monitor configured to compare a level of the input signal with a reference level in real time and configured to determine that speech of a user is input when the level of the input signal is greater than the reference level; a speech recognizer configured to output an utterance in the form of text by performing speech recognition on the input signal when it is determined that the speech is input; a natural language processor configured to extract a domain and a keyword based on the utterance; and a dialogue manager configured to determine whether a previous context is maintained based on the domain and the keyword. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
