[BlindMath] NVDA with MathCAT not reading math

Mon Mar 23 16:02:52 UTC 2026

Hello everyone!

I appreciate all of the thought all of you were putting into this over the weekend!  I have had some partial success this morning.

  *   Steps I have taken: Making sure all browsers (Chrome, Firefox, and Edge) are up to date, running NVDA COM tool, rebooting, right clicking “activate” on MathJax and refreshing page.

  *   Step I could not take: Updating Windows. Windows 11 Enterprise 24H2 is the latest approved version by our university IT dept. and that is what we are all running.

  *   Websites tested:
     *   https://accessibility.psu.edu/math/mathml/#test (MathJax v2.7.0)
     *   https://warwick.ac.uk/fac/sci/physics/research/cfsa/people/pastmembers/robinson/mathjaxtest/ (MathJax v2.7.1)
     *   https://intlpress.com/JDetail/1805889101985456129 (MathJax v3.2.2)

  *   Results:
     *   Firefox: Now working! NVDA/MathCAT correctly reads math from all three of the sites above.  "Sound when starting/ending math speech" is heard.
     *   Chrome: Now working, but only for the MathJax v3.2.2 site. "Sound when starting/ending math speech" is not heard, even on MathJax v3.2.2 site.
     *   Edge: Still not working at all for any of the websites above.  "Sound when starting/ending math speech" is not heard.

My own laptop, also running Windows 11 Enterprise 24H2, NVDA 2025.3.3 and MathCAT 0.7.5 - just like my student’s workstation - reads the math in all three of the above test sites in all three browsers perfectly. NVDA debug log attached (for Chrome and Edge), and thank you again!

Best,

Leigh

Please go into the NVDA menu, then tools, then Run COM Registration Fixing tool... and run that tool, you will need admin access. This has fixed math for me in the past on occasion. What browser are you using?

Hi Ryan,

He is running NVDA 2025.3.3 and MathCAT 0.7.5, both of which he has uninstalled and reinstalled multiple times.

Thanks!

Hi Leigh,

What NVDA version is he using, and what version of MathCAT is he using? Have you tried uninstalling and reinstalling? I'm happy to help troubleshoot.

Best,
Ryan

Hello all!

One of my students has been unable to get his NVDA to read MathML/MathJax properly. His NVDA is updated, his MathCAT is updated, and all his NVDA and MathCAT settings look identical to those on my laptop (Clearspeak speech style and medium verbosity), but when his NVDA encounters MathML/MathJax, it just says "clickable" and moves past the equation.  Can anyone think of anything obvious I have forgotten? I installed my own NVDA/MathCAT so long ago that maybe there is something in the setup I have forgotten about.  He has tried Chrome and Firefox (and rebooted his computer about a hundred times...), but still no luck.

Thanks so much!

Leigh
