My issue is more that you guys actually did some great Japanese voices for stuff like the pushback tugs. Those sound great, but I'm not sure what was done differently about the cabin crew sounds but there are virtually no differences between the en-JP and en-US variants other than the pronunciations of Ls and Rs.
Listen to the first phrase "May I see your boarding pass please". Everything before "please" is so easily an American accent.
And whilst I agree with your "not everyone can recognise a racist stereotype" argument, are you saying everyone in the comments of that reddit thread are native speakers? Did you even read the end of my previous post?
You do however have the ability to know how offensive it sounds.
Very obvious to you maybe, as native speaker, and it doesn't sound very american at all to me (and I guess to most americans), considering the voice is cloned from a japanese person speaking english.
If it is cloned from a Japanese person speaking english, then their level of english is such that there is no accent/american accent, in which case they're a terrible voice to clone because then whats the point? If an italian voice actor had a perfect British accent are they a good model for your "italian accent'ed" english?
You simply cannot say from an accent and stereotype perspective that neither are true, when you have enough people saying that it is.
I'm not here to dump on you or GSX, I've bought and owned every version since basically day 1, and I appreciate the work you do. Which is why I'm even more surprised that when someone informed you that your AI generated voices are offensive, you took the route of "it was ai not me" followed by "how am I supposed to know that" and "well go find your own voice actor".
I'd be fine with you telling me to "go find my own voice actor" or "how am I supposed to know if its offensive" if it wasnt a payware product. Freeware sure, but why do I have to have a product I have paid for cause offense to me everytime I want to use it (you don't give the option to turn regional accents off).
I understand wanting to defend something you made, but when someone who has spent money on your software tells you that it is offensive, that is not the appropriate reaction.
EDIT: I'm not calling you racist by any means, though I do think my use of the word is in fact justified. (strictly describing the stereotype used and nothing else)
