Word-Conditioned Phone N-Grams for Speaker Recognition

Abstract

We extend the state-of-the-art by applying word-conditioning to constrain phone N-gram features used in speaker recognition. Feature-level combination of 52 word unigrams constraining phone N-grams of order 1, 2, and 3 proved to be the best approach. Our system achieves 18% and 27% improvements compared to a non word-conditioned phone N-grams system on… (More)
