When an audience is listening, part of what they are subconsciously hearing is your sense of conviction in what you are saying. That sense of conviction, which is critical, tends to be reduced when the delivery is mainly reading. The reason is reading can easily sound more like regurgitating information with no real sense of understanding of what one is saying. The more authentic the delivery, the better your speech will sound, and it should establish a deeper connection with the audience.
Describe what you plan to do to reduce or to totally eliminate reading when presenting.
