Considerations for Using the Data

Discussion of Biases

There are quite a few dialects present throughout the dataset.

Other Known Limitations

A lot of the sessions were held online, as such the audio quality varies drastically and is sometimes too bad to ensure good transcriptions. The .srt files used are not flawless, as such there might be a few errors in the dataset. Additionally, the alignment will be off from time to time, resulting in missing speech with the full transcript which could increase hallucinations.

Additional Information

Licensing Information
