Being able to read out finger spelling is kinda useless when most of the relevant population can't spell (why bother with an abitrary phonetic encoding for words in a language you don't know)
Newer systems can read entire signs, which is cooler, but still useless because they can't handle the grammar or context. Just some words in isolation.
Don't waste time on this. This is not an accessability tool for the disabled, it is a "feel proud tool" for undergrads with a machine learning library.
The real technological solution that would be helpful is still a few more major advancements away. It needs to handle grammar (ASL has radically different grammar than most spoken languages fyi). Going from a spoken language to a sign language is also significantly more useful.
Go learn ASL (or your local sign language) and encourage others to learn. That effort will do more good in making the world accessible to those who depend on sign language to understand and be understood.
