new words / specific domain

First of all, kudos for such a great platform.

This really isn't an issue and I would like to pay someone for their time to help me. I am having a hard time understanding how I can add domain specific words to the existing model.

After reading https://alphacephei.com/vosk/adaptation and https://alphacephei.com/vosk/lm I am still not sure how to:
1. Correct certain words. ex. model recognizes "web site" but i want it to be "website", or "a s w" where the model recognizes "hey is w)
2. Add new words (domain specific), ex. azure

I tried to find youtube videos and more details. Would someone be wiling to spend help me and I would pay via paypal?
