It wouldn't be a text captcha, then.

It would certainly lose utility for visually-impaired users.

OCR is pretty well advanced by now; the image captchas that used to rely on it now use extremely distorted images.

Apparently I'm a robot. I can't add one + owl + owl and type in an answer I expect to have recognized.
