by Filler words during our day-to-day conversations are okay, because they help us to see that a person hasn’t finished his statement. But during presentations filler words have a bad rep. Since there are no conversations, just a continuous monologue. So too many um and uh create clutter. But eliminating them all is also a bad thing, because filler words make your speech more memorable and help audience understand it better.
