Hi Simon,

thanks again for all the effort put in this documentation! I am running your set-up and would like to give something back.

I am assuming you mean documentation for recording speech and/or converting it speech-to-text. However, please give me more information, I am happy to help.

Hi @peterHeuz , thanks for your positive feedback!

I am talking about the extension of the talk install script which is not covered by this documnetation yet. See https://github.com/nextcloud/vm/blob/669164ac7b6a3a79c0506059c4f5e27b47b0722a/apps/talk.sh#L518-L561

I would be glad if you would create a PR to extend it :)
