Aprx. time to QA/Audit and correct 1 already transcripted audio hour?

[miketcr]

Hello freelancers,

Does anyone have an idea or experience on how long it would take to do QA for 1 already transcribed audio file. 
Sorry if this has already been covered, I searched and read several posts. Only saw posts about Transcriptions and the time it takes to do so vs per per hour or min. etc. 

I am being offered a job, where I am to correct any mistakes.
Not much info given, except that I am listen and read, then correct if there are mistakes, using a platform.

Your responses are appreciated.

Respect
