Well first of all becoming a transcriptionist does not require extensive training (there are several online courses available for those interested), but it does require a great deal of patience. Because you do not select the quality of the recording you are going to copy, you may get low quality and difficult to understand files. The required typing speed is about 65 to 80 words per minute, with an accuracy of at least 97%. If you are a native speaker of the language in recordings with perfect grammar and spelling skills, it is even better, so that you can understand all its features.
