+    It is designed for use with TTS models like Arcana, which currently do
+    not support JSON-based WebSocket protocols (though this may change in
+    the future).
+
+    Limitations:
+        - Does not support word-level timestamps or context IDs.
+        - Intended specifically for integrations where the TTS provider only
+          accepts and returns non-JSON messages.

+        - Arcana and similar models may add JSON WebSocket support in the
