Add paragraph about non-transcribed CAPTCHA audio #3476
Conversation
Closes #3198 Note: Issue #323, from 2018, does bring up the issue of what generated on the fly audio is (live? prerecorded?) and it wasn’t resolved. It’s not clear to me whether this fits under 1.2.1 (pre-recorded audio only) or 1.2.9 (audio-only live), but I’m not sure it matters as both require an alternative.

How is CAPTCHA part of authentication? I seem to remember there was a discussion on that on Github or the mailing list. Since CAPTCHA is not used to identify a particular person but just differentiate human vs. automatic capabilities, this seems misplaced here?

it's a cognitive test as part of an authentication process (rather than a cognitive test in general). but agree, as mentioned before, this is the the weirdness of this particular SC (that really should have been two separate SCs) special-casing things under the mantle of authentication only (i.e. slide 68 of my recent presentation https://patrickhlauke.github.io/wcag-interpretation/?#68 )

@detlev, if you're asking this question, maybe we need to do more than just modify this portion of the document in order to address it. However, my suggestion would be that spawning a new issue asking that question may be a better approach than adding this contextual information -- unless it is your feeling that this changes makes your underlying question more dominant.

@mbgower I'm easy, seeing that the text qualifies "If a CAPTCHA is used as part of an authentication process"
