Vocal Tract Length Perturbation for Text-Dependent Speaker Verification with Autoregressive Prediction Coding

no code implementations25 Nov 2020 Achintya kr. Sarkar, Zheng-Hua Tan

In this letter, we propose a vocal tract length (VTL) perturbation method for text-dependent speaker verification (TD-SV), in which a set of TD-SV systems are trained, one for each VTL factor, and score-level fusion is applied to make a final decision.

Time-Contrastive Learning Based Deep Bottleneck Features for Text-Dependent Speaker Verification

no code implementations11 May 2019 Achintya kr. Sarkar, Zheng-Hua Tan, Hao Tang, Suwon Shon, James Glass

There are a number of studies about extraction of bottleneck (BN) features from deep neural networks (DNNs)trained to discriminate speakers, pass-phrases and triphone states for improving the performance of text-dependent speaker verification (TD-SV).

Time-Contrastive Learning Based DNN Bottleneck Features for Text-Dependent Speaker Verification

no code implementations6 Apr 2017 Achintya Kr. Sarkar, Zheng-Hua Tan

It is well-known that speech signals exhibit quasi-stationary behavior in and only in a short interval, and the TCL method aims to exploit this temporal structure.
