Assuming that the purpose is to keep spam bots from accessing the website,
this may work for the DeafBlind people. As long it is not voice or graphic
only, we the Deafblind people will be happy. Smile.

Would a screen reader be able to read this kind of captcha -

Using this caphchas approach, would not be accessible for the deaf-blind
audience. Many cannot hear the voice.

I've been investigating www.captcha.net recently, which features a sound
file with generated captcha graphics, howeverI wonder if these may be
confusing for non-English speakers.

Briefly looking through the examples at the link you provided makes
one wonder about the accessibility. Metaphors and math may be
difficult for people with cognitive disabilities.

Are you sure you need a captcha? Is it possible to instead use a
server-side service (like Akismet) to deal with spam?
