Elizabeth, one of the members of our Pramy Users Group at the Parkinson Institute in Sunnyvale, CA has a business selling various devices to help PWPs. At one meeting he demonstrated a voice amplifier but at the time I wasn't needing the advice and didn't note it. However, his name is Doug DeVries and his telephone number is (408)253-0243. He is a PWP himself and I know he would be more than happy to hear from you. Best of luck in finding a solution to your problem. Rosemary CG for "Dex" 4/72
