Change way of speaking

Change way of speaking Hello, Do you think that changing the way you speak will allow you to stutter less or have more confidence when giving presentations? Recently, at the funeral of a relative, I gave a speech without stuttering, which doesn't happen very often. But at that moment I felt like I wasn't speaking as usual, my voice was much deeper than usual with more pauses. Have you ever felt this way? Is it good to gradually force yourself to speak in a different way?
