Well, Jim-and-All, I phoned Fonix last Friday to try-and-buy version 4.63, however, they told me they have no stand alone version for linux. They just have a runtime developers kit. I thought $50 for this software would have been reasonable. Also, it may enable me to run oralux-and-YASR on a laptop as well. So are their other companies other than Fonix selling linux dec-talk software? Thanks so much Hart
