Speech recognition

We present the Multilingual TEDx corpus, built to support speech recognition (ASR) and speech translation (ST) research across many non-English source languages.The corpus is a collection of audio recordings from TEDx talks in 8 source languages.We segment transcripts into sentences and align them to the sourcelanguage audio and target-language translations.The corpus is released along with open-sourced code enabling extension to new talks and languages as they become available.Our corpus creation methodology can be applied to more languages than previous work, and creates multi-way parallel evaluation sets.We provide baselines in multiple ASR and ST settings, including multilingual models to improve translation performance for lowresource language pairs.
