Comment Type: technical
Summary of Issue: Audio CAPTCHAs
Comment (Including rationale for any proposed change):
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)
