Abstract
A system and method for identifying a speaker based on dual calculation of voiceprint match scores, using machine learned voiceprint sets and machine learned hashing models to reduce a voiceprint set, normalizing the joint scores, and performing user identification. The system and method include, among other things, a novel normalization technique designed for multitarget detection that considers scores between all enrolled negative list (NL) utterances and the normalization cohort as a single distribution. The system and method include machine learned hashing models to efficiently find a small subset of utterances from enrolled NL utterances and the normalization cohort that are most similar to the test utterance, so that the number of similarity score computations can be significantly reduced in identifying the speaker.
