We have a CSS3 Speech module[1] that is well advanced. The next draft
might well be the last call for comments and the CR is expected next
year.

While that module isn't in CR, we indeed have no official way to make
speech style sheets, except one that is deprecated, but the intention
is clear: we would like people to try out '@media speech' with the
properties in the Speech module and help us finish that module. In
particular, we need another implementation. It doesn't have to be a
browser. Something built on top of an SSML engine would do. Is anybody
working on a speech-enabled product?

'@media aural' remains valid for the few implementations that exist
(which are, as far as we know, either limited to two or three
properties or not publicly available).
