# Kokoro TTS
This skill allows you to generate high-quality AI speech using a local or remote Kokoro-TTS instance.
## Configuration
The skill uses the `KOKORO_API_URL` environment variable to locate the API.
- **Default:** `http://localhost:8880/v1/audio/speech`
- **To Configure:** Add `KOKORO_API_URL=http://your-server:port/v1/audio/speech` to your `.env` file or environment.
## Usage
To generate speech, run the included Node.js script.
### Command
```bash
node skills/kokoro-tts/scripts/tts.js "<text>" [voice] [speed]
```
- **text**: The text to speak. Wrap in quotes.
- **voice**: (Optional) The voice ID. Defaults to `af_heart`.
- **speed**: (Optional) Speech speed (0.25 to 4.0). Defaults to `1.0`.
### Example
```bash
node skills/kokoro-tts/scripts/tts.js "Hello Ed, this is Theosaurus speaking." af_nova
```
### Output
The script will output a single line starting with `MEDIA:` followed by the path to the generated MP3 file. OpenClaw will automatically pick this up and send it as an audio attachment.
Example Output:
`MEDIA: media/tts_1706745000000.mp3`
## Available Voices
Common choices:
- `af_heart` (Default, Female, Warm)
- `af_nova` (Female, Professional)
