+# pipertts_it-IT_dii
+
+This is a text-to-speech voice model for **Italian**. The voice is **Dii**, a female voice. It uses the Piper VITS architecture, exported to ONNX for CPU inference. It was built by voice conversion from the base voice `pipertts_pt-PT_dii`.
+
+## How to use
+
+This is a [Piper](https://github.com/OHF-Voice/piper1-gpl) VITS voice, in
+ONNX format. Use it with any Piper-compatible runtime, or with
+[ovos-tts-plugin-piper](https://github.com/OpenVoiceOS/ovos-tts-plugin-piper)
+in OVOS:
+
+```json
+{
+  "tts": {
+    "module": "ovos-tts-plugin-piper",
+    "ovos-tts-plugin-piper": {
+      "voice": "OpenVoiceOS/pipertts_it-IT_dii"
+    }
+  }
+}
+```
+
+Command line, with the `piper` package installed:
+
+```bash
+echo "Buongiorno, come stai?" | piper --model OpenVoiceOS/pipertts_it-IT_dii --output_file output.wav
+```
