Dear Ben Maurer, Thank you for your comments on the 17 May 2007 Public Working Draft of the Web Content Accessibility Guidelines 2.0 (WCAG 2.0 http://www.w3.org/TR/2007/WD-WCAG20-20070517/). The WCAG Working Group has reviewed all comments received on the May draft, and will be publishing an updated Public Working Draft shortly. Before we do that, we would like to know whether we have understood your comments correctly, and also whether you are satisfied with our resolutions. Please review our resolutions for the following comments, and reply to us by 19 November 2007 at public-comments-wcag20@w3.org to say whether you are satisfied. Note that this list is publicly archived. Note also that we are not asking for new issues, nor for an updated review of the entire document at this time. Please see below for the text of comments that you submitted and our resolutions to your comments. Each comment includes a link to the archived copy of your original comment on http://lists.w3.org/Archives/Public/public-comments-wcag20/, and may also include links to the relevant changes in the WCAG 2.0 Editor's Draft of May-October 2007 at http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-20071102/ Thank you for your time reviewing and sending comments. Though we cannot always do exactly what each commenter requests, all of the comments are valuable to the development of WCAG 2.0. Regards, Loretta Guarino Reid, WCAG WG Co-Chair Gregg Vanderheiden, WCAG WG Co-Chair Michael Cooper, WCAG WG Staff Contact On behalf of the WCAG Working Group ---------------------------------------------------------- Comment 1: Audio CAPTCHAs Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007Jul/0214.html (Issue ID: 2355) ---------------------------- Original Comment: ---------------------------- Audio CAPTCHAs need to include substantial amounts of background noise in order to be secure against robotic attacks Audio CAPTCHAs must also not be captioned for obvious reasons. Proposed Change: To 1.4.6 add: "Except if the audio is provided as a CAPTCHA and a non-audio CAPTCHA is available that provides equivalent access" To 1.2.* add: "Except if the media is provided as a CAPTCHA and an image only CAPTCHA is provided" (similar to the text in 1.1.1) --------------------------------------------- Response from Working Group: --------------------------------------------- We have changed 1.4.6 to include this exception. (changes marked with ***) "1.4.6 Low or No Background Audio: Audio content *** that is not an audio CAPTCHA and *** that contains speech in the foreground does not contain background sounds, background sounds can be turned off, or background sounds are at least 20 decibels lower than the foreground speech content, with the exception of occasional sound effects." Regarding captions, an audio-only CAPTCHA would not be considered multimedia and would therefore not need to be captioned.
