Notable changes to this project will be documented in this file.
+## [v0.1.2] - 2025-01-23
+### Structural Improvements
+- Models can be manually download and placed in api/src/models, or use included script
+- TTSGPU/TPSCPU/STTSService classes replaced with a ModelManager service
+ - CPU/GPU of each of ONNX/PyTorch (Note: Only Pytorch GPU, and ONNX CPU/GPU have been tested)
+ - Should be able to improve new models as they become available, or new architectures, in a more modular way
+- Converted a number of internal processes to async handling to improve concurrency
+- Improving separation of concerns towards plug-in and modular structure, making PR's and new features easier
+
+### Web UI (test release)
+- An integrated simple web UI has been added on the FastAPI server directly
+ - This can be disabled via core/config.py or ENV variables if desired.
+ - Simplifies deployments, utility testing, aesthetics, etc
+ - Looking to deprecate/collaborate/hand off the Gradio UI
+
+
## [v0.1.0] - 2025-01-13
### Changed
- Major Docker improvements:

-> [!INFO]
> Pre-release. Not fully tested
Dockerized FastAPI wrapper for [Kokoro-82M](https://huggingface.co/hexgrad/Kokoro-82M) text-to-speech model
-- OpenAI-compatible Speech endpoint, with inline voice combination functionality
-- NVIDIA GPU accelerated or CPU Onnx inference
+- OpenAI-compatible Speech endpoint, with inline voice combination, and mapped naming/models for strict systems
+- NVIDIA GPU accelerated or CPU inference (ONNX, Pytorch) (~80-300mb modelfile)
- very fast generation time
- 35x-100x+ real time speed via 4060Ti+
- 5x+ real time speed via M3 Pro CPU
-- streaming support w/ variable chunking to control latency & artifacts
-- phoneme, simple audio generation web ui utility
-- Runs on an 80mb-300mb model (CUDA container + 5gb on disk due to drivers)
+- streaming support w/ variable chunking to control latency, (new) improved concurrency
+- phoneme based dev endpoints
+- (new) Integrated web UI on localhost:8880/web
## Quick Start
The service can be accessed through either the API endpoints or the Gradio web interface.
1. Install prerequisites, and start the service using Docker Compose (Full setup including UI):
- - Install [Docker Desktop](https://www.docker.com/products/docker-desktop/)
+ - Install [Docker](https://www.docker.com/products/docker-desktop/)
+
- Clone the repository:
```bash
git clone https://github.com/remsky/Kokoro-FastAPI.git
cd Kokoro-FastAPI
-
- # * Switch to stable branch if any issues *
- git checkout v0.0.5post1-stable
cd docker/gpu # OR
# cd docker/cpu # Run this or the above
docker compose up --build
+ # if you are missing any models, run the .py or .sh scrips in the respective folders
```
Once started:
- The API will be available at http://localhost:8880
- - The UI can be accessed at http://localhost:7860
+ - The *Web UI* can be tested at http://localhost:8880/web
+ - The Gradio UI (deprecating) can be accessed at http://localhost:7860
- __Or__ running the API alone using Docker (model + voice packs baked in) (Most Recent):
