Thanks for your suggestion. I'll check if there is a chance we can use this TTS system for Bulgarian after our update.
Although there are some translation issue with the text. I assume everything is auto-translated.
I'm not actually sure where Clozemaster's text comes from, or how it was translated. It at least seems to be mostly one consistent corpus - pretty much the only male character is called Tom and the only female character is called Mary, and the only language they ever speak about, apart from English, is French ... though I was surprised to see the internet proverb 'Trolling is a art' appear as one of their sentences (rendered into Bulgarian as 'Да бъдеш трол е изкуство' if I remembered correctly, but I guess the ethics of including a deliberate mistake equivalent to the English original is a fraught question). I have reported occasional mistakes that I've spotted, so I guess it may well be auto-translated.
