Semi-supervised speech activity detection with an application to automatic speaker verification
(Elsevier BV, 2017)
articleartikkeli
We propose a simple speech activity detector (SAD) based on recording-specific Gaussian mixture modeling (GMM) of speech and non-speech frames. We extend the conventional expectation-maximization (EM) algorithm for GMM ...
Robust Speaker Recognition with Combined Use of Acoustic and Throat Microphone Speech
(ISCA (the International Speech Communication Association), 2016)
articleartikkeli
Accuracy of automatic speaker recognition (ASV) systems degrades severely in the presence of background noise. In this paper, we study the use of additional side information provided by a body-conducted sensor, throat ...
Spoofing detection goes noisy: An analysis of synthetic speech detection in the presence of additive noise
(Elsevier BV, 2016)
articleartikkeli
Automatic speaker verification (ASV) technology is recently finding its way to end-user applications for secure access to personal data, smart services or physical facilities. Similar to other biometric technologies, speaker ...
