Support for W3C's CSS Speech Module

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Go to http://kushagragour.in/lab/hint/
2. Navigate to tooltips
3. Notice that they aren't announced

What is the expected output? What do you see instead?

Right now they aren't announced.  Ideally they would be announced slightly 
differently.  Ideally we'd be able to leverage something like 
​http://www.w3.org/TR/css3-speech/

So that we could either insert a pause or change the voice family befor the 
tooltip is used.

In ChromeVox it gets ignored. It works in VoiceOver.  

However, there should be some means to convey that the tooltip is distinct 
aurally from the text it is describing.

What version of the product are you using? On what operating system?

Mac.  1.31.4

Please provide any additional information below.

It would be useful to be able to have a standard to address tooltips like this 
in a aurally constructive manner.
