sherpa-onnx-tts
Local TTS using the sherpa-onnx offline CLI.
Install
- Download the runtime for your OS (extracts into
$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/runtime, default ~/.moltis/tools/sherpa-onnx-tts/runtime)
- Download a voice model (extracts into
$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/models, default ~/.moltis/tools/sherpa-onnx-tts/models)
Resolve the active state directory first:
STATE_DIR="${OPENCLAW_STATE_DIR:-$HOME/.Moltis}"
Then write those resolved paths into the active Moltis config file ($OPENCLAW_CONFIG_PATH, default ~/.moltis/Moltis.json):
{
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:
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."
