I've a formula, eg:
where the latex's code is:
\int_{a}^{b} \frac{1}{\sqrt{\rho}} d\rho
The output should be somthing like this: "The integral from a to b of one over the square root of ro in de ro."
I'm aware of this question, but I'm interested in a tool/library/service used by a un*x program "headless" and more the answer is ten years old, I hope something new is available.
