[Blindmath] Screen reader for Calculators?

[Sarah Jevnikar]

Hi all,
Next July, I intend to write several Society of Actuaries professional
exams. These exams require pre-approved Texas Instrument calculators which
I've listed below. Is there anything like a screen reader for calculators? I
called Texas Instrument today and they have nothing except a scientific one
which talks but it is not approved. If not a screen reader, is there an
accessible  financial calculator anywhere?

Thank you in advance,
Sarah

List of approved calculators:

BA-35
TI-30Xa
BA II Plus*
TI-30XIIS*
BA II Plus Professional Edition*
TI-30XIIB*
TI-30XS MultiView*
TI-30XB MultiView
