Are you a great listener? Good! That and solid typing skills are the basic requirements to becoming a transcriptionist online. Generally, you should type at least 60 WPM, and you should be able to type efficiently and accurately. While listening and typing is pretty easy work out of the gate, you will likely have a set of guidelines you need to follow to the letter. But once you get those guidelines down, you can settle in and let your fingers do the talking.
A word of caution: Remember that where very little is required, very little is offered. These jobs don’t pay much, and they are not going to provide a reference for your resume. It may take working at several different of these online jobs to pull in the income you want. And as always, know the signs of a work-at-home scam as you sort through the opportunities.
