Voice Biometrics

Our voice biometrics systems allow automatic speaker recognition to be performed in a flexible way, using an ‘open-box’ architecture and providing a choice of several feature extraction, speaker modelling, and speaker comparison approaches, and supporting the training and adaptation of models with user data at multiple points of the speaker recognition pipeline. Our systems offer forensic speaker comparison, speaker identification and verification using GMM, i-vectors, and state-of-the-art deep neural network-based x-vectors.

Our performance metrics software can be used to interpret the scores returned from ASR and can also be used to estimate a likelihood ratio (LR) under same-speaker and different-speaker hypotheses, enabling the forensic practitioner to make objective estimates of the strength of the evidence in a speaker comparison case.
