Acoustical and perceptual study of voice disguise by age modification in speaker verification
González Hautamäki Rosa; Sahidullah Md; Hautamäki Ville; Kinnunen Tomi (Elsevier BV, 2017)The task of speaker recognition is feasible when the speakers are co-operative or wish to be recognized. While modern automatic speaker verification (ASV) systems and some listeners are good at recognizing speakers from ...info:eu-repo/semantics/article

Impact of Bandwidth and Channel Variation on Presentation Attack Detection for Speaker Verification
Delgado Hector; Todisco Massimiliano; Evans Nicholas; Sahidullah Md; Ming Liu Wei; Alegre Federico; Kinnunen Tomi; Fauve Benoit (IEEE, 2017)Vulnerabilities to presentation attacks can undermine confidence in automatic speaker verification (ASV) technology. While efforts to develop countermeasures, known as presentation attack detection (PAD) systems, are now ...info:eu-repo/semantics/article

Semi-supervised speech activity detection with an application to automatic speaker verification
Sholokhov Alexey.; Sahidullah Md; Kinnunen Tomi (Elsevier BV, 2017)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 ...info:eu-repo/semantics/article
