"""
|

This dataset is derived from paired_voice_audio, but it only supports loading from TSV files generated from the
|
||||
ocotillo transcription engine, which includes alignment codes. To support the vastly larger TSV files, this dataset
|
||||
uses an indexing mechanism which randomly selects offsets within the translation file to seek to. The data returned
|
||||
is relative to these offsets.
|
||||
|
||||
In practice, this means two things:
|
||||
1) Index {i} of this dataset means nothing: fetching from the same index will almost always return different data.
|
||||
2) This dataset has a slight bias for items with longer text or longer filenames.
