But one challenge of giving talks based only on slides is that if you want to recirculate your talk in another form, by publishing it on a blog or rewriting it for journal publication, you don’t have much to work with. So I started recording all of my talks. I just use the built-in voice recorder app on my smartphone, which also doubles as a timer to keep me on track.
This simple habit not only lets me later transcribe a talk for reuse but also solves the problem I often have in class lectures, where I’ll delve into a topic not originally on the outline, and sometimes hear myself saying smart things I’d like to remember to return to in future iterations of the class. By recording class lectures then I have a record of what we covered, should I wish to go back to it.
