All,

I am currently evaluating a site that uses a form protected by Recaptcha.
Even with hearing/comprehension in a normal range, I was unable to come even
close to understanding the provided audio after three tries. This is an
incident report form of a serious nature. The last thing needed is for a
person already shaken by a traumatic event to encounter a barrier such as
this one.

I am aware of alternative methods of protection such as those discussed at:

What would you consider other viable alternatives that both pass WCAG 2.0 at
Level AA and are friendly to folks with a range of disabilities? Thanks
much!

Regards,
