SPEAKER IDENTIFICATION AND VERIFICATION SYSTEM

摘要

The present invention relates to a speaker recognition method and system which applies adaptive component weighting to each frame of speech for attenuating non-vocal tract components and normalizing speech components. A linear predictive all pole model is used to form a new transfer function having a moving average component. A normalized spectrum is determined from the new transfer function. The normalized spectrum is defined having improved characteristics for speech components. From the improved speech components, improved speaker recognition over a channel is obtained.
