Abstract
A method of analysis of an audio signal comprises: receiving an audio signal representing speech; extracting first and second components of the audio signal representing first and second acoustic classes of the speech respectively; analyzing the first and second components of the audio signal with models of the first and second acoustic classes of the speech of an enrolled user. Based on the analyzing, information is obtained information about at least one of a channel and noise affecting the audio signal.
