 In https://bugzilla.mozilla.org/show_bug.cgi?id=525444, Mozilla landed
 support for JS access to OS provided speech synthesis. It appears to be

 vector through computer-specific speech packages which are exposed in an
 enumeratable fashion through speechSynthesis.getVoices().

 We should keep an eye on this in case it gets enabled by default later.
