ultimately I'm not sure that is a tractible problem; any method a screen reader would need to use to decode to speech would require getting the address in clear text via programatic means, which is something that one specifically needs to avoid if we want to stop bots scraping addresses

You could have a button that triggers a captcha that then authenticated a request for the plaintext email.

Or you could just use a spam filter.

you know, you're right, an optional audio capcha alongside these could work quite well. I stand corrected !

Not really a block. I’ve worked on CAPTCHA-solving bots. But it does increase the cost. I’d probably not scrape for emails anyways though, using leaked datasets is likely far more economical.
