There may be some confusion because XSLT has been considered for several 
uses by the Voice Browser Working Group.

In his response I think Jim Larson was referring to the use of XSLT
and ECMAScript as part of a "semantic interpretation" activity that
is coupled with the grammar specification currently available as a draft.

XSLT has definitely been considered as part of the Speech Synthesis Markup 
Language (URL in the subject line).  The omission of XSL aural styling
from that spec is historic and I expect will be corrected shortly.
[XSL was still in flux as the original drafts of SSML were produced.]
The current draft is intended to be a final form representation
of an XHTML+ACSS transformation.  As you point out it is equally 
useful as final form for XHTML+XSL-with-aural-styling.
