Startup Idea: Automatic Lecture Transcription Software

Startup idea to develop a program that provides automated transcription of college lectures, filling in the gaps in students' notes automatically, making the note-taking process easier and more efficient.

I am a student in college and the most annoying thing is having to type what the professor is saying and creating notes. I have no problem with note taking but half the time they are talking so fast I find myself having a tough time getting everything on typed and I type 70 WPM which is above average. If there was a program that could listen to what the professor said and fill in my notes in areas i missed that would be helpful and I would pay money for it.
