  What (*if any*) code could I include a .mobi file that would control the native voice synthesizer?

  That is not possible in any of kindle eBook formats. Amazon is stripping all html which is not supported as they stated it in [Kindle Publishing Guidelines](http://kindlegen.s3.amazonaws.com/AmazonKindlePublishingGuidelines.pdf). Also you don't have access to any of device settings - including Text to Speak.
