+  - Supports manual mic and continuous voice mode (wake word flow).
+  - Best when browser STT is stable in your environment.

+- **`assist_stt`**
+  - Uses Home Assistant STT provider via `/api/stt/<provider>`.
+  - Intended for manual mic input (press mic, speak, auto-stop, transcribe, send).
+  - Continuous voice mode is not used in this provider.
+
+For `assist_stt`, make sure an STT engine is configured in **Settings → Voice assistants**.
