Abstract
A speech distinction method, which includes dividing an input voice signal into a plurality of frames, obtaining parameters from the divided frames, modeling a probability density function of a feature vector in state j for each frame using the obtained parameters, and obtaining a probability Pthat a corresponding frame will be a noise frame and a probability Pthat the corresponding frame will be a speech frame from the modeled PDF and obtained parameters. Further, a hypothesis test is performed to determine whether the corresponding frame is a noise frame or speech frame using the obtained probabilities Pand P.
