Dear Bernard, It sounds like you are experiencing what a lot of other PWP do with their voice. That is, diminution in volume, loudness, almost like hoarseness. One of the things about this situation, is that we have "re-set" our own screening ability as to intelligibility - we think we're adequately loud; but others say "What?and Hunhh?" frequently enough to know that this is a real phenom. You can be assured that this has not escaped scientific investigation, primarily in two locales - Iowa State, where resides The National Center for the Study of the Voice, and in Denver/Boulder Colorado, by Dr. Lorraine Ramig. She is the director of the Lee Silverman Voice Treatment Center at the Wilbur Gould Voice Treatment Center, all a part of the Denver Center for the Performing Arts. (I never have used the word "center" that many times in such short a space) Dr Ramig works with treating the Parkinson voice, almost entirely. In the last few years, she has trained speech pathologists her methods, all over the world. The basic structure is 1 hour of speech therapy per day, 4 days of 7 for 4 weeks. This method has helped a large number of us PWP to retain close to our pre-Parkinson voices. Or, alternatively, you could just have a bad cold. Regards, Don Penny PS A lot of your posts contain words implying urgency. Perhaps more reading about the many little things of Parkinsons, outlook, coping, striking peace with this injury/illness might be useful.
