Deep CNN Based Feature Extractor for Text-Prompted Speaker Recognition

Sergey Novoselov, Oleg Kudashev, Vadim Shchemelinin, Ivan Kremnev, Galina Lavrentyeva

ICASSP 2018accepted

Deep learning is still not a very common tool in speaker verification field. We study deep convolutional neural network performance in the text-prompted speaker verification task. The prompted passphrase is segmented into word states - i.e. digits - to test each digit utterance separately. We train…

STC anti-spoofing systems for the ASVspoof 2015 challenge

Sergey Novoselov, Alexander Kozlov, Galina Lavrentyeva, Konstantin Simonchik, Vadim Shchemelinin

ICASSP 2016accepted

This paper presents the Speech Technology Center (STC) systems submitted to Automatic Speaker Verification Spoofing and Countermeasures (ASVspoof) Challenge 2015. In this work we investigate different acoustic feature spaces to determine reliable and robust countermeasures against spoofing attacks.…
