I understand the need for CAPTCHA's, but due to the fact that not everyone in this world can clearly make out the text in an image. I personally would use "logic questions". You do not have to be "blind" to use these. Although they are helpful for us as well, they in my view benefit people that have other eye problems. Some examples would be Stigmatism, Dyslexia, and Diabetic Retinopathy. The numbers for those with eyesight problems is clearly in the rise not just for the blind but the aging population is on the rise as well.
Here is the link:

In addition, in case you are wondering those sounds Meant for making the web accessible by hearing it does not work very well. As a few friends of mine have pointed out, I have been blind for 30 years and am still unable to get the whole audio. Pros and cons to each, but I am sure you know where I stand on this.
A person came up with the project of webvisum an add on to Firefox that tries to fix this problem, but there are some images it is unable to ocr.

This is a great project, but can be bad if someone gives the link to someone and they just do that for getting past things. My point is there are pro’s and con’s to both options, but it is up to the webmaster. One more thing, for those who are deaf the second option is a bit better if you are also blind and deaf like a few people I know and the big problem they don’t render on a braille display. Heck half the time sighted people can’t see them, but they are also needed until another improved option comes along.
