sherpa-onnx-tts

Local TTS using the sherpa-onnx offline CLI.

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."
