What is ASL morphemes???
Do you mean mouthing english word like you speak without being vocal in english grammar structure while signing asl?
Like this *sign* "me go store saw friend chat all night wow real nice see her"
and you mouth this "I went to the store and I saw my friend. So we chatted the whole night and it was really nice to see her"?
How that work out? Because english is much longer than sign unless you're motormouth LOL.
What about expressive mouthing that have no real vocal meaning like "shaaaaa" when signed hit the gas pedal to go very fast?
Well for me I'm weird because I sort of combined mouthing some words I signed and use expressive mouthing for some other too. And when someone signed to me I'll mouth what they signed sometimes so I understand them better.
I don't know if I can really speak because I never use it in public not even with my fiance because I'm extremely shy about using my real voice to talk and when my CI surgeon forced me to speak he wrote down "very good, exceptionally good for your type of hearing loss"
Any tips on how to break the shyness to use my voice to sharpened my oral skills?
