Data Generation Using Pass-phrase-dependent Deep Auto-encoders for Text-Dependent Speaker Verification

no code implementations3 Feb 2021 Achintya Kumar Sarkar, Md Sahidullah, Zheng-Hua Tan

In this paper, we propose a novel method that trains pass-phrase specific deep neural network (PP-DNN) based auto-encoders for creating augmented data for text-dependent speaker verification (TD-SV).

UIAI System for Short-Duration Speaker Verification Challenge 2020

no code implementations26 Jul 2020 Md Sahidullah, Achintya Kumar Sarkar, Ville Vestman, Xuechen Liu, Romain Serizel, Tomi Kinnunen, Zheng-Hua Tan, Emmanuel Vincent

Our primary submission to the challenge is the fusion of seven subsystems which yields a normalized minimum detection cost function (minDCF) of 0. 072 and an equal error rate (EER) of 2. 14% on the evaluation set.

On Bottleneck Features for Text-Dependent Speaker Verification Using X-vectors

no code implementations15 May 2020 Achintya Kumar Sarkar, Zheng-Hua Tan

We further investigate the impact of the different bottleneck (BN) features on the performance of x-vectors, including the recently-introduced time-contrastive-learning (TCL) BN features and phone-discriminant BN features.
