In Harry Potter, do we have a question about how the Dark Lord's chosen name is pronounced? Apparently there's a JKR interview answer on this, but all I can find on SFF is
scifi.stackexchange.com/q/114325/4918 "Which names (besides for Voldemort) do the movies pronounce wrong?" and
scifi.stackexchange.com/q/112401/4918 "What is the correct pronunciation of Hermione?"
