Speech Therapy: Many people have spent much time in stuttering therapy with limited success. There is a far better solution -speech aids. The Edinburgh Masker and/or Delayed Auditory Feedback (DAF) have been a God Send for many. Before beginning stuttering therapy tell the therapist you want to try a speech aid. If it works for you, that is great and no further stuttering therapy is necessary. If it does not work, then you can try traditional therapy.
