## Dataset Structure
This dataset is a collection of audio files that have been stored as tar files, each containing a set of audio files. On average, each tar file is 5GB in size.
- All tar files are stored in either in the `audio` or `audio2` directories. 
- The `licenses.jsonl` file contains the license information for each audio file.

## Dataset Creation

### Source Data

Data was downloaded via the archive.org API. No data inference was done. No preprocessing was done.

### Annotations

No manual annotation is done. We download only source audio. In particular, there is no "forced alignment" or "segmentation" done on this dataset.

## Considerations for Using the Data

Our data is downloaded from archive.org. As such, the data is biased towards whatever users decide to upload there.

Almost all of our data is American accented English.
