Re: support for sub and sup in screen readers and talking browsers

Instead of asking users, I believe you should be asking the screen reader 
developers if or when they plan to support it.

User agents have a role in the total accessible solution equation too.

I copied GW Micro's WindowEye support e-mail above.

support for sub and sup in screen readers and talking browsers







Hi,

I recently read in a report on accessibility of mathematics and 
science that screen readers can't tell the difference between sub and 
sup in HTML, so a<sup>n</sup> and a<sub>n</sub> are both rendered the 
same on a Braille display, namely as "an".

I would like to collect some more data on the support of sub and sup 
by screen readers and talking browsers and I have put together a 
small test page for this purpose: <http://tinyurl.com/2qll7h>. The 
page contains five examples of superscript and subscript and a few 
combinations of these.

With Fire Vox, the code samples given above are read as an emphatic 
"an". The output for the other expressions is also misleading. I 
would appreciate it if users of screen readers and talking browsers 
could tell me what their systems output for each of the five 
examples. I will then add the test results to the test page.

Best regards,
Christophe
