This is a fork of the original Kokoro repo, in order to provide easy inference on Replicate. I am not affiliated with the original Kokoro authors, and this is not an official release of the Kokoro model. Similar to the Huggingface Space, this implementation provides automatic text splitting to support long form text inputs. See the original README below for more details.
