Hi Nikita, thanks for that explanation and for your work on this. Sounds superb.

Hi James,
nvMathViewer solves other problems. It does not replace MathPlayer or
Access8Math, but complements them.
For example, there is a user who doesn't know LaTeX, but wants to read a
formula like this.
nvMathViewer will display LaTeX as MathML and then the user can view it
using MathPlayer.
The user needs to select a line
x_{1, 2} = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}
and perform a special gesture.
After that, he can hear this line as
"x sub 1 comma 2 end sub equals the fraction with numerator negative b plus
or minus the square root of b squared minus 4 a c and denominator 2 a"
nvMathViewer is a solution for those who don't know LaTeX or AsciiMath, but
need to read formulas like this sometimes.
Best regards, Nikita.

How does this differ from MathPlayer and the support already present in

Hello everybody!
nvMathViewer has been released. It is an a add-on that can be used to view mathematical content in LaTeX and AsciiMath notations as MathML.
These notations are widely used to write mathematical symbols and formulas in computer systems. However, understanding LaTeX and AsciiMath requires special knowledge and skills that the average user may not have, such as a simple schoolboy or a humanitarian student. In addition, reading these notations directly may not be convenient enough, because it does not provide additional opportunities for analyzing the structure of formulas.
nvMathViewer solves these problems and enables blind users to quickly view any LaTeX or AsciiMath notations using special functions of NVDA for non-visual reading mathematical content and structural navigation through it.
Add-on for NVDA 2019.3 and newer -
