A funicular ticket window’s speech recognizer dumps a raw line. Staff then ask a pretrained token classifier to mark station names and car numbers so a map still can highlight the right platform photo. What is the text-arm experiment?
Select an answer to reveal the explanation.
Short Explanation
The ear already wrote a raw line. The next tool is a highlighter that tags station names and car numbers so the map can light the right photo. That highlighter sits on top of audio — it is not a new ear.
Full Explanation
Pretrained token classification on recognizer output is a text-arm NLP experiment that feeds tags to a visual or routing stage. It does not replace the acoustic model or regenerate photos. Framing the trial this way keeps speech recognition fixed while testing whether entity tags improve platform-photo highlighting.
