I know that feel. My way of approaching this is the following: You know that feel when you're talking in a plain voice because you're uncomfortable because you actually do not want to talk right now? Try alternating the pitch of your voice. Sound more interesting. One important factor is to stay hydrated. This way your voice is naturally a bit deeper. Speaking is a responsive task, so if you like hearing your own voice, you will like talking out loud. You are more comfortable and therefore more confident. Also don't forget to take pauses. As long as you want. Take a breath. Preparation is the key. Being comfortable and getting used to reading out loud is also important. Do not listen to those who are telling you to avoid reading out loud. Conquer your fear. "All I insist on, and nothing else, is that you should show the world that you are not afraid. Be silent, if you choose; but when it is necessary, speak - and speak in such a way that people will remember it." (Mozart)
