I have had a speech-easy for several years. It's not a miracle cure. It may help when reading but we all know that is not a cure for natural speaking. It often times gets uncomfortable in my ear and I have to just take it out. It would take a lot of practice concentrating on the changed sound of your voice being feeded to one ear, and still concentrating on what you are trying to say. It's not perfect. Two speech pathologists have tested me with it and without it and have told me there is little to no difference. It may work great for some, but not for others.
