[GoogleCodeExporter]

What steps will reproduce the problem?
1. Navigate to http://jsfiddle.net/l0mars01/o94wkomL/
2. Read "Visible" object.

What is the expected output? What do you see instead?
Expected: hear "Spoken hint Visible".
Actual: hear "Visible".

What version of the product are you using? On what operating system?
ChromeVox 40.0.2178.0 on Chrome 40.0.2214.45 beta-m
OS Name: Microsoft Windows Server 2012 R2 Datacenter Version 6.3.9600 Build 9600

Please provide any additional information below.
CSS rules shouldn't apply to user agents specifically excluded by media queries.
Though the span containing "Spoken hint " is assign CSS property "display: 
none" inside a "not speech" media query, this shouldn't affect speech user 
agents like ChromeVox, which should still read it.
CSS 2.1 specifies a speech media type
