Haha, nice one, there will be a blacklist of words based on the US and UK English Dictionary too.
Also it is “Consonants” and “Vowels”. Also since when is “R” a Vowel?
I might also remove certain Consonants and Vowels from the List, because not everyone can actually say them out loud. Such as how many Asian people cant do the rolling “R”, or how Germans like me cant do the “Th”. Not to mention the many ways you can ambiguously pronounce “Ch”.
