text: how do i find a program which calls a cell phone and then converts text i type into speech to that person? it should be free. the person you call should also be able to speak back to you which is translated into text. i think there may be an operator involved. i used to know a guy that did that, type what one person said & said what the other person read. this is who deaf people call people on the phone. but i believe that the deaf person used a special device not a computer, but i dont see why there wouldnt be a way to use a computer.  here i just did a search on tty software: http://search.yahoo.com/search?p=tty+software&rs=11&fr2=rs-top&toggle=1&ei=utf-8&fr=fp-tab-web-t
