Need automatic diarization of audio files of tutoring sessions

I'm flirting with the idea of having science tutors that I train audio tape their sessions and upload them to an audio analysis site, or use analysis software that counts the minutes spent each person spent talking. Apparently this is called diarization.

I help run a program that trains upper-division undergraduates to tutor first-year undergraduate students in science.
The best way to learn science is to practice answering problems yourself, but tutors (like teachers) really want to lecture instead of listen and ask probing questions.
I'm very familiar with education research, and there's a tiny bit on using "lecture time" as a gross measurement of poor teaching. When presented with the time you spend droning, I suspect tutors will get better at letting the students talk.
But I'm totally unfamiliar with audio analysis or software in this area. We're talking about perhaps 100-200 hours of tutor recordings per week, so automating this upon upload would be awesome.
Is anyone familiar with reasonably priced software that might do the job?
