MaSS - Multilingual corpus of Sentence-aligned Spoken utterances

Posted: September 29, 2021 3 min.

The MaSS dataset is a large and clean speech dataset of 8,130 parallel spoken utterances across 8 languages (56 possible language pairs). The languages covered (Basque, English, Finnish, French, Hungarian, Romanian, Russian and Spanish) allow to carry out research on speech-to-speech alignment as well as on translation for typologically different language pairs. This data set is extensively described in the following paper (Zanon Boito et al., 2020).

We are not allowed to share the audio files, however, we provide the extraction pipeline in the following repository. If you have troubles building the dataset yourself, feel free to email me!. Inside the dataset folder, for each language we provide:
