Indeed, one of the motivations for the work on style sheets is to
allow non-visual rendering.

Exactly. In CSS terms this would be properties and corresponding
values. Do you have an initial list of properties you need/want? My
initial guess would be along the lines of:

property values

volume <db> | <number>
pitch <Hz> | raised | lowered
gender male | female | child
affect sad | excited | ..

In addition, some speech synthesisers come with "personalites"
included, but they're probably a bit too "device-dependant" for a
specification?

I know nothing about the parameters involved in controlling braille
devices.

Great, I look forward to putting this into the specification.
