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.

    you might want to reword your question. Maybe use the term presenter or something Mar 11, 2013 at 15:59

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: http://layersmagazine.com/powering-search-with-audio-metadata-using-premiere-pro.html
