1. A method of performing text independent speaker recognition including speaker identification, comprising: sampling overlapping frames of a speech signal, computing a feature vector for each said frame of said speech signal, comparing each said feature vector with vector parameters and variances stored in a codebook corresponding to an enrolled speaker, accumulating a number of frames for which the corresponding feature vector corresponds to vector parameters and variances in a codebook, identifying an enrolled speaker or detecting a new speaker in response to results of said accumulating step or said comparing step, respectively, controlling a function in accordance with said identifying step, and initiating an enrollment procedure when a new speaker is detected before or during control of said function.
