None of the open source models I've seen are as "well-rounded", production ready as Eleven Labs. Though for example bark is really great at prosody: https://suno-ai.notion.site/Bark-Examples-5edae8b02a604b54a4... And piper isn't bad at speech quality: https://rhasspy.github.io/piper-samples/

We might only be a few papers away from a good open source Elevenlabs competitor.
