I really admire those who can speak with a smooth and relaxed voice. When listening to some podcasts, youtube videos, or presentation, some videos like this [one](https://www.youtube.com/watch?v=J0NuOlA2xDc) are narrated by someone with relax and smooth voice without any uhms, I really enjoy listening to this kind of people, and sometimes envy them, to the point that I end up diverting from the main point and focus on how they speak. This happened multiple times at my college. Does this happens to anyone here?
