[pmwiki-users] Screen-reader friendly PmForm captchas

Without using ReCaptcha — because Google data-mines everything so I don't even want to load tech from them on my site — is there a way to fallback to a text-based code on forms for captcha when someone is using a screen reader?
I know this may defeat some of the purpose of using captchas to stop bots. I also use a honeypot which can be frustrating when using assistive tech because only upon getting an error does it tell the user that they need to ignore the "Subject" field that sighted people cannot see.
However, I have blind website viewers since my site is about mental health disabilities, it needs to be accessible to the disability community as a whole. I was informed of the issue today by someone using assistive technology who could not submit comments on my site. Usually they get an audio captcha on other sites. I thought it would fall back to text, but that only happens if the server side fails to create images — not if the client side doesn't perceive images.
A question captcha might be the best solution that would work with all technology :/ a rotating question would be best so it's not always the same answer.
