I did hs and collegiate debate & speech to some success. The keys to speaking "smoothly" outside of the technical aspects of cadence, tone, etc, is more organization and thought-flow than anything else. Treat your audience like their stupid and hand-hold them through the argument you're trying to make. Organize your speech, even if informally, around some natural structure. i.e. intro --> relate intro to topic of speech --> argument --> summary of points that defend your argument --> detailed breakdown of each point --> conclusion where you resummarize your argument and the points that defend it If you can't engage your speakers with some sort of natural charisma or speaking ability at the very least make sure that your points are stated clearly in a well organized easy to follow way.
