When we make fr economics radio, we do our best to clean up the language of the people who are being interviewed. The writing that has been written with consideration and is read, which doesn't have filler, that is much more pleasant to listen to. So if you're talking to a listener on this podcast or in a lecture, you don't want to sound like a news anchor reading from a tele prompter. One of the three inventors of the first tele prompter, i learned recently, was irving berlin kan, who was a nephew of irving berLIN, which is kinane.
Also: why do we pad our speech with so much filler language?
