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.
You can get TeX to parse the MathML, see for example xmltex, https://www.ctan.org/pkg/xmltex which comes with some mathml setup, however I wouldn't do it that way these days, I'd convert the MathML using XSLT, see for example pmml2tex which is available on github
The XSLT at
https://github.com/davidcarlisle/web-xslt/tree/master/pmml2tex
converts MathML to TeX it's been fairly extensively used over the years including generating almost all the images in Chapter 4 of the MathML3 spec (as part of a pipeline Content MathML to Presentation MathML to TeX to images.)
It currently skips maligngroup and produces
From the supplied XML.
It would be trivial to add the extra & by hand to restore the alignment. Changing matrix to aligned and adding two & produces

Currently mathjax speech rules are probably the most advanced thing here, you could access them via a headless browser but see
https://docs.mathjax.org/en/latest/basic/a11y-extensions.html
Or more directly to the underlying speech rule engine
