Compare transcribed text with original audio (approx 2 hours of audio)

I have a number of transcription files - each one is around 20 minutes.

I have used a speech to text processor to make a transcript which is relatively accurate. I would like someone to take each segment and compare against the transcription, separating out speakers making minor corrections, highlighting where audio is not clear, etc. The key thing is that the MEANING of the audio is clearly represented, not a perfect word for word transcription.

I've personally corrected 20 minutes of audio in 30 minutes, so it's not hugely time consuming.

FURTHER CLARIFICATION:

I have several files. Each file is a "project". Each project file has been split down into roughly 20 minute segments, to make it easier to work with. There is a corresponding transcript for each 20 minute segement.

There are 22 hours in total, spread over 16 projects. I want to get everything back by Wednesday or Thursday next week (10th, 11th August) - but intend to split the projects over a number of freelancers. So, (for example) a freelancer could opt to do two projects, comprising 4 hours of audio, delivered by Wednesday.

I'm available on Skype to discuss and while you are working if you have questions.
