  This paper introduces Multilingual LibriSpeech (MLS) dataset, a large
multilingual corpus suitable for speech research. The dataset is derived from
read audiobooks from LibriVox and consists of 8 languages, including about
44.5K hours of English and a total of about 6K hours for other languages.
Additionally, we provide Language Models (LM) and baseline Automatic Speech
Recognition (ASR) models and for all the languages in our dataset. We believe
such a large transcribed dataset will open new avenues in ASR and
Text-To-Speech (TTS) research. The dataset will be made freely available for
anyone at http://www.openslr.org.
