It looks like feature requests are being made here, so if all right, I'd like to request Speech Synthesis support be added to allow a user to have an article or a portion thereof be spoken to them. It's not universal across browsers, but Chrome, Safari, and Opera currently support it. Firefox apparently has some infrastructure for it started, but it is not yet working there. Microsoft is supposedly considering support: http://caniuse.com/#search=speech
I've implemented some code at http://bahai.works (see http://bahai.works/The_Hidden_Words/Arabic for one sample). Though the JavaScript code (about the first 1/4 of http://bahai.works/index.php?title=MediaWiki:Common.js ) could be cleaned up a bit and be put in a library form, it is working fine, and should work fine on other sites as well.
You can either push play to start from the beginning of the page text or highlight a block of text to have that text spoken. It currently has some code to ignore certain elements by ID or class (as those are used by templates on the site to indicate text, such as paragraph numbers or headers, which should not be read out loud).
