Sorry, I guess? It's been an industry standard phrase for a pretty long time. Screenreaders probably have a historical reason why they're named the way they are, but the short version is that's just what everyone started using. A lot of software terminology is like that, it's weird to people who are unfamiliar with it because there's no central committee somewhere that decides what everything should be named.

If you're trying to do a search online for the kind of tool you're looking for, probably the phrase you would want to search for is "OCR software", short for Optical Character Recognition, or if you're trying to tag images just straight-up "image recognition."
