Dear Tom, Thanks for telling me about the speech "machine" which you have found and use yourself - it is probably a great deal less expensive than the Speech Enhancer. I have seen biofeedback type of things, and I think they would be a great adjunct to anyone undergoing speech therapy for PD such as LSVT. Sadly, for Bob, I think he may have gone beyond the sort of device which you use. Nevertheless I am VERY interested in what you use because there is certainly room for all sorts of equipment. So I will look up your site and let our Speech Pathologist know about it. I wonder why SP don't pull out all the stops when they take someone on for Speech therapy?
