Well, perhaps it’s not entirely free. I do appreciate that your time is valuable and the following method is not entirely automatic. But it’s pretty darn close! Before we get into the specifics, there are a few small challenges to this method that you should know: 1) you’ll need an iOS device, such as an iPhone or iPad, 2) it takes a bit of manual labor to correct the inevitable minor mistakes, and 3) the dictation app only records up to a minute of audio at a time. It also works best if the recorded voice is cleanly isolated from any other sounds, like background music, ambient noise, or other people talking at the same time.
