Preferred Communication Methods for Nonverbal Individuals

i either text or use text-to-speech on my phone, and with my parents there are a few ASL words and phrases we know so I can communicate faster

AAC is advanced audio coding basically a device that speaks for u

I took ASL 3 out of 4 years of high school and so with friends who know asl i try to communicate with that but most of the time i will just write out stuff or type it out, or i just will listen and not input into a conversation but im curious, what is ACC?
