There's lots of great german voices here which should be better: https://elevenlabs.io/app/voice-library/collections/SHEPnUB9...

The voice selection matters a lot for this research preview

Not a native speaker by any stretch, but all the voices sounded like 'intercom announcer' or 'phone assistant' to me. Not natural in the slightest.

I tried German in the preview box there, and it had a very strong English accent.

I listened to a story about dragons.

It sounded okay. Only in the middle somewhere, the loudness seemed to change drastically.
