Download the runtime for your OS (extracts to$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/runtime , default~/.openclaw/tools/sherpa-onnx-tts/runtime ) 2. Download a voice model (extracts to$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/models , default~/.openclaw/tools/sherpa-onnx-tts/models ) First, resolve the active state directory: ``bash STATE_DIR="${OPENCLAW_STATE_DIR:-$HOME/.openclaw}" Then write those resolved paths into the active OpenClaw config file ( $OPENCLAWCONFIGPATH, default ~/.openclaw/openclaw.json): json5 { skills: { entries: { "sherpa-onnx-tts": { env: { SHERPA_ONNX_RUNTIME_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/runtime", SHERPA_ONNX_MODEL_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/models/vits-piper-en_US-lessac-high", }, }, }, }, } The wrapper lives in this skill folder. Run it directly, or add the wrapper to PATH: bash export PATH="{baseDir}/bin:$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 SHERPAONNXMODEL_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."`
