To not send this thread further off-topic than it already is…
The problem with trying to suggest/impose/etc a “correct” English is that it doesn’t exist. Even in the UK there are many varied regional dialects, from the Queen’s Received Pronunciation, Home Counties (me), Cockney (Lock, Stock & Two Smoking Barrels), Brummie, Glaswegian, Liverpudlian, Mancunian, West Country (this is what I imagine @Dobster sounds like) & various flavours of Welsh, Scottish & Irish. And that’s just the UK, you then need to add in any other English speaking country with all of their regional accents, and then there’s @Boardman21’s English…
When I googled the words form the original thread (deicide, fanatacism& riposte), I got the pronounciation that I expected (day-ih-side, fah-nah-ti-cism, rip-ost (as in rip & the ost from Ostend) ), not the ones you gave.
