You can just get the Latex Code directly from a File on Arxiv.org

To understand Formulas better when reading Papers, I have just gone to Arxiv.org to get the Latex file version of the PDF.
(go to "Other Formats" option and download the compressed file and view the Latex file inside it)
(In windows it doesn't have an extension so I add a .rar extension to the saved file, open it in Winrar and use the built in
View button inside Winrar to view the Latex file)
Then I searched the viewed Latex file for the words that appear just before the formula (from the PDF) , and cut and pasted the Latex Code from the View of the Latex fie)
Paste that into Google Bard after the pompt:
"How do you read this formula in Latex out loud? Explain every symbol name and it's meaning. "
I found Google Bard the best at this.

It would be great if LaTex-OCR could pass it to Bard with the prompt above before the LaTex text.
Now you can learn how to pronounce the Letters you might not know and how to read it out loud or to yourself.

Further enhance it by using a good Text to Speech engine. (Oh yeah, Bard Speaks now)
BTW --- Does anyone know how to scrape the Speech from the output window in Google Bard (upper right corner is the Speaker Icon)?
