# 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`

- `af_heart` (Default, Female, Warm)
