Check which languages a screen reader can identify by name

[mitchellevan]

Can screen readers even identify the name of a language? This can be important, so a user either knows to avoid the language (when they know they don't know it), or knows the name of the language so they can go find a capable synthesizer.

How to test:

• Make one big page with ~100 lines of lang="xxx", one for each language in my large sample.
• Maybe it's enough for each line to contain some digits.
• Or if necessary, I could try generating language endonyms from JavaScript Intl methods.

I started the test page and got some initial results. Digits seem enough for this narrow technical test, but I need a spreadsheet both for entering results and for keeping track of which language is which.
