SYSTEM FOR DETECTING SPEECH INTERVAL AND RECOGNIZING CONTINOUS SPEECH IN A NOISY ENVIRONMENT THROUGH REAL-TIME RECOGNITION OF CALL COMMANDS
First Claim
1. A method for recognizing a speech of a speaker, the method comprising:
- receiving an input speech spoken by the speaker;
receiving a subsequent input speech spoken, by the speaker, subsequently to the input speech;

Abstract
A continuous speech recognition system 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.
