There are a lot of automated transcription services for podcasts, but they can range in both quality of transcription and price. One of the newer tools on the scene is Whisper from Open AI.
Whisper has been praised by podcasters for its accuracy and language detection - however, it can require some in-depth technical knowledge to implement, including loading scripts and additional tools onto your PC or Mac.
Thanks to audio optimization and repair platform Auphonic, this potential barrier has been removed, as you'll see in this video (thanks to Adrian McIntyre for the heads up on this).
