Stuttering is a brain dysfunction where there is an interruption in processing when the user is speaking. By using DAF the user is no longer speaking and hence our stutter is greatly reduced. The speaker finished speaking a fraction of a second ago. DAF is wonderful. My kids use DAF and it helps them immensely. I use the Edinburgh Masker which Masks out my speech and is also wonderful. My kids DAF comes from Casa Futera Technologies and I would highly recommend their devices. Other than that I would recommend that you keep using the phone and computer. If there is software, use that. The important part is that DAF works and it is indeed a miracle. Keep up the good work.
