Summary: | 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 select frames for an adaptively weighted cepstrum. Frames with a predetermined number of resonances are selected for cepstrum analysis. An adaptively weighted cepstrum is determined from a new transfer function. A normalized cepstrum is determined having improved characteristics for speech components. From the improved speech components, improved speaker recognition over a channel is obtained. |
