Hi Phill,
I thought that media type 'aural' was valid in the current CSS2 - and that it was deprecated in the current working draft of CSS 2.1
One reason for hearing something different would be using CSS to replace the SUP element in a mathematical expression - for example 2<sup>4</sup> - using CSS a visual user could see the equivalent of the SUP effect while a non-visual user could hear 2 'raised to the power' 4

Nope, not that I know of.  And Aural CSS was also deprecated, see http://www.w3.org/TR/CSS21/aural.html 

A. 1. ... The type 'aural' is now deprecated. 

This means that a style sheet such as 
@media speech {
 body { voice-family: Paul }

is valid, but that its meaning is not defined by CSS 2.1, while 
@media aural {
 body { voice-family: Paul }

is deprecated, but defined by this appendix.

And why does it matter for breadcrumbs?  Sighted users see the greater than sign.  Why would you want to hear anything different than what is displayed visually?  Screen readers provide access to the visual content, they are not for everybody.  Whether one use the greater than sign, or the vertical bar, or colon, or some other character or icon is a different discussion than providing technical access.  What ever the sighted user sees is what the screen reader user wants access to as well.
