But how exactly do you memorize a script? There are many different methods but this is the approach I use and the one that I use to teach other people in workshops and coaching.
Most important of all you should not try to memorize and entire script and deliver it exactly a written. Unless you are a talented actor reading a script written by a talented writer it will always sound stiff and heartless. People can recognize very easily when you are effectively playing back a recorded announcement because the rhythm is usually wrong and the emphasis is rarely where it should be. A recital like this will have less impact and instead of inspiring people you might bore them. Memorizing the exact wording also has the disadvantage that if you have a temporary blackout it is hard to recover.
