A Speaker's Power. I say spoken words are more powerful, especially when presented by an eloquent speaker, author, etc. When written, it’s hard to imagine what kind of person is talking, how they sound when they say it. One can hear other people’s attitudes toward a subject, depending on how they elevate or lower their voices. Take one of Obama’s speeches for example. When hearing it, you can tell how enthusiastic, or maybe concerned he is about a particular topic he addresses. That option is not available in the written word.
