It’s not really, ASL is it’s own distinct language from English, like most sign languages. ASL is most closely related to French Sign Language, which still isn’t anything related to French and has its own linguistic features and independent development. Because of this translating ASL to English (or any other language) is no easier than translating to or from any other spoken language.
And to add on a little, ASL is like any other language in that it has regional dialects. It's why many people introduce themselves with their name and where they learned to sign.
One of the more common examples from teachers is the sign for SLOW. On the west coast, we sign it as the flat palm being pulled slowly back along the extended non-dominant arm. But in the south and parts of the east, it is signed as the Y sign, thumb against the cheek, being tilted forward.
The way you fix this casually is to ask the other person to finger spell or mime what they meant. I can't see AI being able to do that well for a while but maybe..?
Sure, but machines are actually pretty good at spoken and written translation these days, so I would expect that once the image recognition is solved they could handle ASL readily as well.
Since ASL doesn't have a massive corpus of scrabeable training data (at least I would think). It's probably on the harder side when it comes to creating machine translators.
in theory with a mastery of speech recognization one would assume you could then apply that to any diction that has an accompanying ASL translator to derive ASL elements from the contexts given by the spoken word.
in practice that's all difficult, if at all possible -- but just sayin; we have decently good speech interpretation at this point, perhaps we aren't far from self-training ASL against something similar.
