Chatterbox
- Fully free / open source
- Tested by us
Chatterbox is Resemble AI's own open voice model, for people who want local speech from the company that trained it. Turbo and Nano are smaller versions of the same project. You run it on your computer, and you still supply the machine.
Tested on CPU only. The original model ran about 4 times slower than real time, and Nano ran faster than real time. The published package needed an older setuptools version to install.
