Sonix looks like a very cool automatic transcription service. First 30 minutes of testing is free, so you can know it will do the job before you plunk down any money.
Looking through the transcriptions, it’s accuracy is pretty impressive. Kind of funny that it transcribes “Inerrancy” as “RNC”, but I think it can be trained to improve over time.
It can also separate out by speaker and timestamp each paragraph.
And it does a bunch of languages too. Was able to use it to help our son with his Spanish homework.
