very surprised to discover that the inaccuracy of automatic captions isn't common knowledge. most people in my circle know that human-made, accurate captions are better, but i've found a lot of folks under that "video tutorial" textpost I just reblogged telling everyone who wants to read instead or who need captions about automatic captions, and that they should just use those.
So in case no one's told you this before, because it makes sense if you don't use them to be unaware: automatic captions are wrong a lot. a LOT.
Especially with overlapping voices of course, but even with one speaker, a clear microphone, and no background music, it can miss entire sentences or replace words with other ones.
For either a person who needs written instruction or a person with hearing difficulties, they're very impractical. so they don't actually solve the problem of needing captions or regular text.
Manual captions work much better for those who are hard of hearing or have processing difficulties. They of course don't come with an automatic transscript, though, which loops back to point of that video post: we need written-only options as well.
