That's a dumb joke. Yes, I hope to look in detail at their performance on a couple of low-resource languages. Without lots of speakers and data, I think good metrics are hard to come by. I've found that in Meta's massively-multilingual TTS - what looks impressive at first glance, you can see performance is quite bad on smaller languages.
Half joking - hopefully, we can still contribute something to this to this field. Looking forward to doing some tests with this.
