Thanks for you effort, I’ve been looking for this! But there are many pronunciations missing, for example try “exanthem” or “anogenital” or many other words (from the Medical part of MW-Online2020), your work doesn’t show the sounds for these words, but the main dictionary does. I’d appreciate if you could address this issue. Your work has 105k entries, but I believe the actual number of pronounced words are way more than that.
Is there any chance that you might be able to do the same for the new OED, or Oxford Living/Lexico? With those two having massive number of pronunciations, it’d be super great as well.
