The Lee Silverman technique - which in my lay opinion is the only one that really works - was developed by Dr. Lee Ramig of Denver, Co. Her e-mail address is [log in to unmask] She has written me that there are five essential concepts of the technique. 1) exclusive focus on voice and improving vocal loudness. 2) High effort treatment. Patients increase the amplitude to generate a louder voice. 3) intensive treatment 4 sessions per week for 4 weeks. 4) calibration - focus on self monitoring 5) quantification to motivate patients. There have been articles published in Advance magazine Feb 26, 1996; and elsewhere. There is also a video tape with some exercises in it that can be purchased, but I would have to do some checking to find the address. I will do that if you are interested. Allan
