SYSTEM FOR DETECTING SPEECH INTERVAL AND RECOGNIZING CONTINUOUS SPEECH IN A NOISY ENVIRONMENT THROUGH REAL-TIME RECOGNITION OF CALL COMMANDS
First Claim
1. A system for detecting a speech interval and recognizing continuous speech using real-time recognition of call commands, wherein:
- when a speaker speaks a call command, the call command is recognized, confidence rate of the call command is measured, and a speech interval spoken subsequent to the call command is applied to a continuous speech recognition engine at a moment at which the call command is recognized, thus recognizing speech of the speaker.

Abstract
The present invention relates to a continuous speech recognition system that is very robust in a noisy environment. In order to recognize continuous speech smoothly in a noisy environment, the system selects call commands, configures a minimum recognition network in token, which consists of the call commands and mute intervals including noises, recognizes the inputted speech continuously in real time, analyzes the reliability of speech recognition continuously and recognizes the continuous speech from a speaker. When a speaker delivers a call command, the system for detecting the speech interval and recognizing continuous speech in a noisy environment through the real-time recognition of call commands measures the reliability of the speech after recognizing the call command, and recognizes the speech from the speaker by transferring the speech interval following the call command to a continuous speech-recognition engine at the moment when the system recognizes the call command.
