Description:

Possibly need a way to define page context dictionaries for text-to-speech.
See https://github.com/darobin/respec/issues/108 for some background.

Basically, you could define (in one location) that ✔ and ✘ are spoken as "True" and "False" rather than needing to define it in the markup for each use.

<!-- Note: the 'text' role is a 1.1 proposal. -->
<span role="text" aria-label="True">✔</span>
<span role="text" aria-label="False">✘</span>

We could also use something like this for phonetic hints for proper nouns or terminology that is uncommon outside the context of the document (and therefore mispronounce by the text-to-speech engine), where the text is not replaced, but the string is used to hint at the correct pronunciation.

I was thinking something along the lines of:

// contextual text alternatives for unicode chars
// (otherwise these would be spoken literally as the unicode descriptions such as "heavy ballot x"
window.tts.phonetics['✔'] = 'True';
window.tts.phonetics['✘'] = 'False';

// contextual pronunciation of proper nouns or other terminology
window.tts.phonetics['Knowbility'] = 'nobility';
window.tts.phonetics['WAI-ARIA'] = 'way aria';

It's possible this should use a phonemic alphabet for the pronunciation strings, but I'm not sure about the l18n implications of that decision at the time of this writing.

window.tts.phonetics could return a dictionary of all set values such as:
{ '✔':'True', '✘':'False', 'Knowbility':'nobility', 'WAI-ARIA':'way aria' }
