I've not used one but several people have mentioned successfully using an amplifyer named ChatterVox. It requires wearing a small fannypack but no one mentioned that being a detriment. On this board, go to the Archives Section, type in ChatterVox to read past comments. You might also search Voice Amplifyers.While working, I did have a voice amplifyer on my telephone and it worked great -something you might think about for home. Many states have programs allowing you to get the use of a home amplifyer for free (comes under the catagory of voice and hearing impaired).
