METHOD AND SYSTEM FOR ESTABLISHING HANDSET-DEPENDENT NORMALIZING MODELS FOR SPEAKER RECOGNITION

摘要

A method and apparatus is provided for establishing a normalizing model suitable for use with a speaker model to normalize the speaker model, the speaker model for modelling voice characteristics of a specific individual, the speaker model and the normalizing model for use in recognizing identity of a speaker. A normalizer module (231) within a scoring module (215) uses the normalizing score (229) to normalize the speaker score (225) thereby obtaining a normalized speaker score (217). Based on the normalized speaker score (217), a decision module (219) makes a decision (221) of whether to believe that the test speaker (203), whose utterance was the source of the speech data (213), is the reference speaker (403).
