Work Notes: Using OpenAI’s Whisper for Speech to Text


New Day: Fri Dec 23 2022 21:36:39 GMT-0600 (Central Standard Time)

I am tried of being on Mint Linux and having poor speech to text capability so I am going to make a web app and host it on this site.

I am using this repo as a starting point.

And I found that repo by looking through the show and tell page of OpenAI’s official repo.

When I set it up viz. install the python scripts and then run the right python file it gives me an error code 500 internal server error.

In detail:
