I have been a transcriptionist for seven years already. I have always enjoyed this kind of work. My WPM is 90. Along the way, I also learned how to make subtitles for closed captioning jobs, which I also thoroughly enjoyed.
I have excellent command in English even though it's not my native language. I have good understanding of the grammars and spellings, especially US English spelling. I am very focused even though I prefer to work at home. I have been working at home for nearly four years now. I usually finish a one-hour video per day but that depends on the quality.
