Hi Olaf

This doesn't need to be fixed in WCAG or HTML as it is not a constraint
Refer to example scenarios where alt text may be useful http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#examples-of-scenarios-where-users-benefit-from-text-alternatives-for-images

Furthermore supporting more than one channel (e.g. text to speech plus visual display) in the very same moment can be very useful. All this is not about "either or", it is about options (a minimal set of options, more is always OK), and each user should have mechanisms available to make use of these options in any fashion and combination.
