Transcription services vary greatly in terms of cost, so it’s impossible to give an answer that applies across the board. Basic audio transcription, for example, might cost between USD $0.50 and $2.00 per minute, where specialized services will inevitably cost more. Some projects, such as those involving medical or legal transcription, have rigorous quality control requirements and can be more expensive. Also, services that charge by projects or milestones are usually more expensive than those that charge by the hour. Data transcription services may conduct a preliminary analysis of your project to get a better understanding of the scope of work and costs involved.
