We present a new algorithm for speaker recognition (the Sequential Non-Parametric system, or SNP) that has the potential to overcome two limitations of the current approaches. It uses sequences of frames instead of one frame at a time; and it avoids the need to model a speaker with mixtures of Gaussians by scoring the data non-parametrically. Although at an early stage in its development, SNP's output can be interpolated with that of our GMM system to outperform state-of-the-art GMM's. Comparative results are presented for the 1998 NIST Speaker Recognition Evaluation test set.
