I have zero understanding why its not something that governments can provide through an online pre-recorded trainings, why is it so difficult to learn deaf sign languages to the point of most known practical way to do it is by getting a minor degree in it (most usually in education)? If anyone wondering which sign language, I’m interested in learning more than one if I find a feasible way to learn them so: American Sign Language/Black American Sign Language (dialect - both are used in the US and Canada), Brazilian Sign Language, British Sign Language, Catalan Sign Language, French Sign Language, Inuit Sign Language, Quebec Sign Language, Swedish Sign Language
I had to learn ASL when I worked as a relay operator because there was a possibility I could be asked to help facilitate video conference calls through the service.
There are probably courses you can take if you have a community college in your area.
