Abstract :
A method of matching a set of speech parameters for identifying and verifying speakers using singular value decomposition is presented. The set of stored reference parameters yielding the largest ratio of singular values when mapped with the parameters of the utterance of an unknown speaker is considered closest to the unknown. An average identification score of 80% was observed on a small set of test utterances using short-time energy and zero-crossing rate with a fixed number of segments
