An ongoing accessibility problem has to do with robot harvesting of free services vs. disability access to those services. http://www.w3.org/TR/turingtest One of the current strategies is to make optional CAPTCHA transactions available that depend on different human functions: one you need to see, another you need to hear, one you need to work logic puzzles, etc. It would be helpful for the 'universal' interaction design if there were any audio-only audio-CAPTCHA practice in the wild to benchmark. Is anyone here aware of voice-enabled or other IVR applications that use a muddy prompt to weed out robot callers? Or is this unnecessary because the phone call to access the IVR in the first place is enough of a barrier compared with a TCP/IP connection? Or it's useless because of the prevalence of good speech recognition in this domain? Al PS: Compare with the discussions of the under-development reCAPTCHA audio CAPTCHA. http://tinyurl.com/ywyqs2
