Which language do AI voices still get wrong for you?

I'm building Voxmint, a text-to-speech tool that started because AI voices kept getting Vietnamese tones wrong. It now has 113 voices in 24 languages, with regional accents like Hanoi, Saigon and Huế, Cantonese and Taiwan Mandarin.

If you make voice-overs, courses or videos in a language other than English: which language or accent do current tools still get wrong? Mispronounced names, wrong tones, a "news anchor" voice when you wanted a casual one?

Send me a short line in your language and I'll reply with how Voxmint reads it, and be honest if it's not good enough yet.
