Where can I find in what language a movie was filmed?

On the page: https://help.imdb.com/article/contribution/titles/languages/GSCRBZYEH5NX5SXL# it says "The IMDb languages section records the languages spoken in titles in the database." Where is that section? I've looked in "Filming & production" and in "Tech specs" which, to me, would seem the most likely locations, but I didn't see it in either of those pages (for a few movies, anyway).
