Transcription, as long as anyone can remember, has always been a process that works with the involvement of a person. At one end, you have the source file and on the other side, there is the destination file. In the middle of these two – source and destination – there is the human interpreter of sorts doing all the heavy lifting.
Technology is always marching ahead, coming up with faster and better ways of doing things that were previously thought be impossible. Transcription is a complicated task, but it looks like technology is finally catching up. This is made possible with advanced algorithms and hardware tech that enable much of it to be completely digitized.
