-This application opens two YARP ports: an `<prefix>/rpc:s` port that allows to request a dictionary/model change and to mute/unmute the microphone, and a `<prefix>/result:o` port that broadcasts the transcribed text. The default prefix is `/speechRecognition`, but it can be changed with the `--prefix` option.
