Not Yet. The Oh Caption plugin is still in development.
2016-09-15: The first cut of the server side is now complete. The work on the browser side is just beginning.
2017-02-22: The first cut of the plugin is just about complete. I expect to have it out to beta-testers within a month.
2017-02-23: I completed the first pass at the Reader documentation today.
2017-02-28: I am going to announce this plugin for beta testing tomorrow. I now have a Firefox and Chrome version of the plugin. Hopefully, I will have an official, public release by the end of March.
2017-03-01: It turns out there is an accessibility bug in Chrome which prevents screen readers from being able to see any plugin extension preferences.
2017-07-20: My patch for the above Chrome bug has now made it into the stable release of Chrome. I have put out a call for testers on a message board for assistive technologies and am currently waiting to be approved to join a Facebook group where I will post the same announcement.
