+# sherpa-onnx-tts
+
+Local TTS using the sherpa-onnx offline CLI.
+
+## Install
+
+1. Download the runtime for your OS (extracts into `$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/runtime`, default `~/.openclaw/tools/sherpa-onnx-tts/runtime`)
+2. Download a voice model (extracts into `$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/models`, default `~/.openclaw/tools/sherpa-onnx-tts/models`)
+
+Resolve the active state directory first:
+
+```bash
+STATE_DIR="${OPENCLAW_STATE_DIR:-$HOME/.openclaw}"
+```
+
+Then write those resolved paths into the active OpenClaw config file (`$OPENCLAW_CONFIG_PATH`, default `~/.openclaw/openclaw.json`):
+
+```json5
+{
+  skills: {
+    entries: {
+      "sherpa-onnx-tts": {
+        env: {
+          SHERPA_ONNX_RUNTIME_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/runtime",
+          SHERPA_ONNX_MODEL_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/models/vits-piper-en_US-lessac-high",
+        },
+      },
+    },
+  },
+}
+```
+
+The wrapper lives in this skill folder. Run it directly, or add the wrapper to PATH:
+
+```bash
+export PATH="{baseDir}/bin:$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 `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."`
