Hiya,
I've been teaching public speaking/presentation skills for many years. I definitely slur and skip alot when my sx are active, but one of the tricks I teach my classes is to control pace by acknowledging natural pauses in speech, like written punctuation marks.
One of the fears of public speaking is a fear of silence, and the feeling of needing to fill it.
Silence is OK. It gives your brain and tongue a chance to catch up.
