# Chatterbox TTS Backend This directory contains the FastAPI backend for the Chatterbox TTS application. ## Project Structure - `app/`: Contains the main FastAPI application code. - `__init__.py`: Makes `app` a Python package. - `main.py`: FastAPI application instance and core API endpoints. - `services/`: Business logic for TTS, dialog processing, etc. - `models/`: Pydantic models for API request/response. - `utils/`: Utility functions. - `requirements.txt`: Project dependencies for the backend. - `README.md`: This file. ## Setup & Running ### Prerequisites - Python 3.8 or higher - A Python virtual environment (recommended) ### Installation 1. **Navigate to the backend directory**: ```bash cd /path/to/chatterbox-ui/backend ``` 2. **Set up a virtual environment** (if not already created): ```bash python -m venv .venv source .venv/bin/activate # On macOS/Linux # .\.venv\Scripts\activate # On Windows ``` 3. **Install dependencies**: ```bash pip install -r requirements.txt ``` ### Running the Development Server From the `backend` directory, run: ```bash uvicorn app.main:app --reload --host 0.0.0.0 --port 8000 ``` ### Accessing the API Once running, you can access: - API documentation (Swagger UI): `http://127.0.0.1:8000/docs` - Alternative API docs (ReDoc): `http://127.0.0.1:8000/redoc` - API root: `http://127.0.0.1:8000/` ### Development Notes - The `--reload` flag enables auto-reload on code changes - The server will be accessible on all network interfaces with `--host 0.0.0.0` - Default port is 8000, but you can change it with `--port `
