sherpa-onnx-tts

Sherpa-onnx-tts enables offline text-to-speech synthesis by wrapping the sherpa-onnx CLI tool. Use this skill to generate audio files from text locally without cloud dependencies by configuring a runtime environment and voice model, then invoking the command-line wrapper with input text and output file path specifications.

# sherpa-onnx-tts

Local TTS using the sherpa-onnx offline CLI.

## Install

1. Download the runtime for your OS (extracts into `~/.openclaw/tools/sherpa-onnx-tts/runtime`)
2. Download a voice model (extracts into `~/.openclaw/tools/sherpa-onnx-tts/models`)

Update `~/.openclaw/openclaw.json`:

```json5
{
  skills: {
    entries: {
      "sherpa-onnx-tts": {
        env: {
          SHERPA_ONNX_RUNTIME_DIR: "~/.openclaw/tools/sherpa-onnx-tts/runtime",
          SHERPA_ONNX_MODEL_DIR: "~/.openclaw/tools/sherpa-onnx-tts/models/vits-piper-en_US-lessac-high",
        },
      },
    },
  },
}
```

The wrapper lives in this skill folder. Run it directly, or add the wrapper to PATH:

```bash
export PATH="{baseDir}/bin:$PATH"
```

## Usage

```bash
{baseDir}/bin/sherpa-onnx-tts -o ./tts.wav "Hello from local TTS."
```

Notes:

- Pick a different model from the sherpa-onnx `tts-models` release if you want another voice.
- If the model dir has multiple `.onnx` files, set `SHERPA_ONNX_MODEL_FILE` or pass `--model-file`.
- You can also pass `--tokens-file` or `--data-dir` to override the defaults.
- Windows: run `node {baseDir}\\bin\\sherpa-onnx-tts -o tts.wav "Hello from local TTS."`
