Video Transcription Comparison

I'm looking for someone to complete a piece of analysis around transcription accuracy. We have four videos and we want to compare the accuracy of human transcription (which we'd need you to do) vs. a software product.

The videos are:
1. Kent Panopto:

2. Medical Video:

3. Accented Fluid Mechanics Video (really good video to use to show how it deals with complex stuff with stronger accents):

4. Calculus Video (dude speaks quick and it's a great one to show its speed):

The right person will transcribe each of the above videos. They will then run the same videos with a software product that will provide a transcription. The two transcriptions should then be compared and the differences identified.

Looking for someone to start on this asap.

Please provide a price and timeline for completing the work.
