Indeed. I was surprised by that as well. Sounded like a Dutch speaker with a muffled voice behind a screen.

Might just be that English is fairly close to German and the like but as English speakers it doesn't sound like English to us because we know English so it gets mapped as a similar but different language.

Confirms my thought that Dutch sounds like unintelligible babbling :)

[vintermann]

Especially funny as the main authors are Dutch.

Ah. Perhaps it was trained on Dutch speakers, not English.

[sjwright]

That would explain it. Would be interesting to hear babbling trained with other languages and accents.

To my German ears it sounded definitely English, not Dutch, like a very hard to understand dialect.
