Most of what I wrote in my 2017 article is correct (but I’d probably need to update some of the AppleScript).
But unless you have lots of time on your hands (or work on very difficult recordings), I would strongly suggest that you use Whisper, the OpenAI solution to automatic transcription. It requires basic command line skills, but nothing that you can’t learn in a 10-minute video tutorial. Your machine specs will also make a difference: my 2.8 GHz Quad-Core Intel Core i7 2015 MBP with 16gb of RAM requires about 1.5~2x the time of the soundtrack to produce a very good transcription (of Japanese interviews) that I will later have to edit to produce something useable.
The github page is here:
https://github.com/openai/whisper, and includes plenty of links that you might want to read.
