Development of Bilingual ASR System for MediaParl Corpus

Petr Motlicek, Milos Cernak, David Imseng

The development of an Automatic Speech Recognition (ASR) system for the bilingual MediaParl corpus is challenging for several reasons: (1) reverberant recordings, (2) accented speech, and (3) no prior information about the language. In that context, we emp ...
