+#### OSC spec
+
+LanguageIdentifier listens on port 9898 by default and responds to the following OSC messages:
+
+* **/listen**: start listening
+* **/listen _state_**: start/stop listening
+  - state: bool, 0 - stop, 1 - start
+* **/autostop**: enable listening auto stop after detection
+* **/autostop _state_**: enable/disable listening auto stop after detection
+  - state: bool, 0 - keep listening, 1 - stop on detection
+
 #### macOS
 
 For macOS, the application binary can be invoked from within the .app bundle to pass commandline arguments:
