License of the data

[noe]

First, thank you for the great dataset and the article.

I have a question regarding the license of the data, which I could not find in the repository or in the audio zip file:

Given that this dataset is derived from the CDRC dataset and that it has CC BY-SA 3.0 license (as it is a work derived from Wikipedia), I understand that this dataset must have the same license, because the original license forces derived works to keep it (in the ShareAlike clause).

Can you please confirm?
