This is another point that OTM's "The Divided Dial" series covered. It's both a creative feature of the medium and one which makes systematic study of it challenging, as there's often no official recording and study requires either researches making their own recordings or listening live, and in either event, listening at best at perhaps 2x realtime speed, which means that analysis is slow. (How much AI and speech-to-text services might assist in this I don't know.)
