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."
