How practical is this?? I've used some of these and they can help a lot. But what's going to be crazy amazing is the use of various realities to practice with, to engage with, and research with all thing public speaking. BTW, presentation guru is worth signing up for. It's free and pushes out great content about presenting for greater impact. Would love to know what public speaking tools others are using, if any.
