The Zero Resource Speech Challenge 2015
Maarten Versteegh,Roland Thiolliere,Thomas Schatz,Xuan Nga Cao,Xavier Anguera,Aren Jansen,Emmanuel Dupoux +6 more
TL;DR: The Interspeech 2015 Zero Resource Speech Challenge aims at discovering subword and word units from raw speech The challenge provides the first unified and open source suite of evaluation metrics and data sets to compare and analyse the results of unsupervised linguistic unit discovery algorithms as discussed by the authors.
Proceedings ArticleDOI
Evaluating speech features with the Minimal-Pair ABX task: Analysis of the classical MFC/PLP pipeline
TL;DR: A new framework for the evaluation of speech rep- resentations in zero-resource settings is presented, that extends and complements previous work by Carlin, Jansen and Hermansky and applies it to de- compose the standard signal processing pipelines for computing PLP and MFC coefficients.
Proceedings ArticleDOI
A summary of the 2012 JHU CLSP workshop on zero resource speech technologies and models of early language acquisition
Aren Jansen,Emmanuel Dupoux,Sharon Goldwater,Mark Johnson,Sanjeev Khudanpur,Kenneth Church,Naomi H. Feldman,Hynek Hermansky,Florian Metze,Richard Rose,Michael L. Seltzer,Pascal Clark,Ian McGraw,Balakrishnan Varadarajan,Erin Bennett,Benjamin Börschinger,Justin T. Chiu,Ewan Dunbar,Abdellah Fourtassi,David Harwath,Chia-ying Lee,Keith Levin,Atta Norouzian,Vijayaditya Peddinti,Rachael Richardson,Thomas Schatz,Samuel Thomas +26 more
TL;DR: In this article, the authors summarize the accomplishments of a multi-disciplinary workshop exploring the computational and scientific issues surrounding zero resource speech technologies and related models of early language acquisition and present two strategies for integrating zero resource techniques into supervised settings, demonstrating the potential of unsupervised methods to improve mainstream technologies.
Journal ArticleDOI
Mothers Speak Less Clearly to Infants Than to Adults A Comprehensive Test of the Hyperarticulation Hypothesis
Andrew J. Martin,Thomas Schatz,Maarten Versteegh,Kouki Miyazawa,Reiko Mazuka,Emmanuel Dupoux,Alejandrina Cristia +6 more
TL;DR: A comprehensive examination of sound contrasts in a large corpus of recorded, spontaneous Japanese speech demonstrates that there is a small but significant tendency for contrasts in infant-directed Speech to be less clear than those in adult-directed speech, and suggests that theories of infants’ language acquisition must posit an ability to learn from noisy data.
Proceedings ArticleDOI
Phonetics embedding learning with side information
TL;DR: It is shown that it is possible to learn an efficient acoustic model using only a small amount of easily available word-level similarity annotations, and the resulting model is shown to perform much better than raw speech features in an ABX minimal-pair discrimination task.
