dict. for blind person

[Mogens Jensen]

Dear Seelangers - one blind girl has asked me to put this question to
you: is there any electronic dictionaries (russian-english-russian) as
good as the paper issues for the seeing people? They must be correct
and give information of declination, meaning and use within different
areas (tecnics, law, business...) - and they must run under Windows
with a russian speech-module. - Any good advice for blind slavists
using computers? - Thank you in forehand, Mogens Jensen
