[Nfb-web] Captcha Question

[Peter Donahue]

Hello Robert and everyone,

    Captchas like the sound captcha still lock out deaf-blind site visitors. 
My wife has normal hearing and she finds audio captchas difficult to 
understand. If the Towsend folks scramble the audio as is done with many 
other captchas this solution is nothing but a joke!

Hello:

     Jonathan Lazar at Towson University came up with a CAPTCHA called
Soundzright (sp?). It works by asking the user to press the spacebar when a
particular sound is heard. For example, it might ask, "Press space when you
hear the dog bark." The user then hears a series of sounds such as breaking
glass, a baby crying, piano music and a dog barking. The sequence repeats
three times. If the user presses the space at the right time, the CAPTCHA is
solved.

I have also seen logical CAPTCHAS such as which number is larger 6 or 5?
Hope this helps.

Regards,
Robert
