I'm in a math oriented problem solving discipline. I am recording demonstration problems using Camtasia and either a tablet PC or Excel.

How do I slow my speaking speed down? I talk way too fast, I think.

Octo, one method you might try is pronouncing every word very carefully and deliberately. This will automatically slow down your rate of speech, with the added bonus of ensuring your text is clear to those people listening.

For a long time, I also used to write "SPEAK MORE SLOWLY!!!" on the top of all my conference papers and lecture notes.

I do the same thing. Talk way too fast! If you figure out a trick, let me know!

Pause often.  You may want to write out your explanations and note where to pause or slow down in the sentence or section of your presentation.  Choosing which words to stress for meaning also helps slow down the rate of delivery. 

I suspect you may be increasing your rate of speaking during your presentation because you either get excited or are trying to pack as much information as possible into the video.  You may want to consider breaking the explanations into several shorter videos rather than one longer version.

I have found that when I write out a script, I sound like an automaton with no inflection when reading it. At least I sound interesting and interested without a script.  It's probably the packing in too much information thing going on and the fact that I love my subject and happen to be a fast talker (no idea how that happened as I'm from slow-talking Southern state).

I am breaking things into shorter videos (although not in the introductory chapters) in most of the more technical chapters. I'm doing a short lecture video on a concept. Then a demonstration video (working a problem). Then, a short lecture video on the next concept, etc.

I wonder also if some of the difficulty comes from the fact that you don't have an audience. When we're lecturing to a class, it's easier to see when you need to stop, slow down, or restate something based on the expressions in front of you. Could you perhaps find a volunteer to play the role of befuddled student?

I do think you are right. however, I don't know how to get a volunteer who'd actually know enough to follow the lectures (have the pre-reqs) and have enough time or inclination to listen to me lecture over an entire semester of the course (which is what I'm preparing for next semester's online version).
