I imagine we'd have the self-restraint not to go quite that far with it, but yes. (dear god i couldn't even finish that video)
We'd probably just emphasise the wrong syllable of multi-syllable words a lot.
Like, that sentence would be pronounced
"We'd [pro-BOB-ly] just [em-PHASS-ise] the wrong [sy-LABB-le] of multi-[sy-LABB-le] words a lot."
And we'd also emphasise "ed", like
The quick brown fox [jump-ed] over the lazy dog
The flow of speaking doesn't allow for corrections/better ideas like typing does, though, so we'd probably just latch onto a few words that we'd always pronounce wrong.
I wouldn't need help on that front, because I am terrible at pronouncing words I've only read.
(i legit thought banal rhymed with anal)
But remember that annoying spelling was murdered brutally by either Orange or Silver (or both) so wrong-emphasis would also likely be killed without mercy.
