I thought to do this when I started reading the pinned post titled 'Listening-Reading Method and Spanish'.
https://farkastranslations.com/bilingual_books.php
I encoded it in 112kbps opus to an ogg file using ffmpeg (it's mono, ~731MB, 15:12:58 long): https://github.com/holdengreen/lingtool/blob/main/streams/center-earth-journey-es-en-original-botched.ogg
I wrote the script to process the text file at: https://farkastranslations.com/books/Verne_Jules-Voyage_au_Centre_de_la_Terre-fr-en-es-hu-nl.zip
Here is the script (https://github.com/holdengreen/lingtool/blob/main/src/center-earth-parallel.py):

Run it with python3.9 and use python3.9 -m pip install to install the dependencies such as PyTorch.
This took maybe five hours to generate on my i7 6700HQ laptop. And btw I counted 13 exceptions either Exception("Model couldn't generate your text, probably it's too long") or one was UserWarning: Text string is longer than 1000 symbols.. This means I think the text is too big or there were some symbols or something it can't handle. I will investigate. ValueError(s) don't seem to be much of an issue tho.
There were 2155 translation pairs in total (most being large paragraphs) so missing 13 isn't a huge deal. The format of the file is separated by \t and \n. It comes in chunks where the paragraphs in different languages are seperated by the tabs and those chunks where the parallel translation moves on to the next set of equivalent paragraphs are separated by new lines. English is at index 1 and spanish at index 2.
Can't wait to use this tomorrow on my walks.
hope I don't get in trouble for this
