## Install

For the fastest local smoke test, install the system engine:

```bash
pip install "realtimetts[system]"
```

On Linux, install PortAudio headers before installing PyAudio:

```bash
sudo apt-get update
sudo apt-get install python3-dev portaudio19-dev
```

On macOS:

```bash
brew install portaudio
```

For cloud engines, local neural engines, CUDA, `mpv`, and current packaging
caveats, see [docs/installation.md](docs/installation.md).
