Bonjour Jack,
We do have lessons / language pages about pronunciation in French. It's a work in progress though and it's on our to-do-list among other things ;-)
You will find great tips about pronunciation in French here: Glossary-Pronunciation
Also, these two links from one of our partners' site might be useful too:
https://www.lawlessfrench.com/faq/pronunciation-key/

I hope this is helpful.
Bonne journée !
