user3761: I was wondering if there is an easy way to detect presenter (speaker) changes from a video clip. I have some presentation / panel / seminar type videos, and want to add markers whenever the speaker changes in the stream. It can be when someone from the audience asks a question, or when another panel starts talking. 

user4426: You can use the speech recognition function within Adobe Premiere to (kind of) do this.  It will analyze a long piece of video, and attempt to create a text script of the speech within the video.  If you tick "identify speakers" before it begins, it will write "[speaker 1], [speaker 2]" etc each time it identifies a change in speaker.
However, the success rate is not massively high.  Adobe claim about 75%, with high-quality audio, which seems about right, but is too low to make it a generally useful feature for most people.
There's a step by step guide on how to use it here:
