🔥🔥🔥✓ VerifiedFreeQuick setup

🧰 Not standalone. This skill ships with firecrawl/openclaw and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

sherpa-onnx-tts

Local TTS using the sherpa-onnx offline CLI.

Copy & paste — that's it

npx skills add firecrawl/openclaw --skill "sherpa-onnx-tts" --full-depth

Run this in your project — your agent picks the skill up automatically.

Install

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

Update ~/.openclaw/openclaw.json:

{
  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:

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

Usage

{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."
