Overview
IBM Watson STT Service
Pros:
- 16 hours a month included in service. 0.02 cent a minute after that see pricing.
- Speed. In autoEdit, always takes 5 minutes to transcribe any duration of audio or video.
- Generally pretty accurate (my opinion, judge for yourself)
- Supports a number of languages see here. Including distinction between British and American English.
Cons:
- Need to provide card details for pay as you go fee.
- is in the cloud so no offline support.

- Easy to setup credentials
- Generally pretty accurate (my opinion, judge for yourself)

Gentle Open Source STT
Pros:
- Free as in free speech as well as in free beer.
- Working locally on your machine. No internet connection needed because of that, good for sensitive material.
- Open source github repo and I made a node module to work with the API .
Cons:
- Not as accurate as IBM one (in my opinion, but decide for yourself).
- Only support US english STT.
- In autoEdit, at the moment not as fast as IBM one, takes a little longer then the length of the media. (eg 27 min takes 30 min to transcribe).
