TL;DR: This paper describes data collection efforts conducted as part of the RedDots project which is dedicated to the study of speaker recognition under conditions where test utterances are of short duration and of variable phonetic content.
Proceedings ArticleDOI
Text-dependent speaker recognition using PLDA with uncertainty propagation
Themos Stafylakis,Patrick Kenny,Pierre Ouellet,Javier Pérez,Marcel Kockmann,Pierre Dumouchel +5 more
TL;DR: A phrase-dependent PLDA model with uncertainty propagation is introduced and it is shown that despite its low channel variability, improved results over the GMM-UBM model are attained.
Proceedings Article
Brno University of Technology system for Interspeech 2009 emotion challenge.
TL;DR: Different feature types and modeling approaches successfully applied in speakerand language recognition are investigated and the submitted system can achieve an 16% and 9% relative improvement over the best dynamic and static baseline system on the 5-class task, respectively.
Journal ArticleDOI
Application of speaker- and language identification state-of-the-art techniques for emotion recognition
TL;DR: This paper describes the efforts of transferring feature extraction and statistical modeling techniques from the fields of speaker and language identification to the related field of emotion recognition and shows how to apply Gaussian Mixture Modeling techniques on top of it.
Proceedings Article
iVector Approach to Phonotactic Language Recognition
TL;DR: The proposed iVector paradigm shows comparable results to previously proposed PCA-based phonotactic feature extraction and support vector machines (SVM) and logistic regression (LR) techniques.
