Have you noticed that people on a conference call or webinar “ah” and “em” more than usual? There might be a few reasons for this:
-They are less focused than in a face to face exchange. It is more difficult to stay engaged in a phone presentation so the “ah”s and “em”s are used while they try to reconnect to the conversation.
-Research shows that people who present on line don’t rehearse as much as when they have a face to face meeting, so they may be at a loss for words.
If you are the presenter in this situation, remove all distractions (no multi-tasking), focus on the conversation and add a little more oomph to your delivery.
