The Institute for Stuttering Treatment and Research is a self-funded institute of the University of Alberta’s Faculty of Rehabilitation Medicine. We offer specialized treatment to children, teens and adults who stutter. In addition, we conduct research into stuttering, offer advanced professional training for speech-language pathology students and clinicians, and promote public awareness of stuttering and its treatment. One of the treatment options is SpeechEasy. is an Altered Auditory Feedback anti-stuttering device, delivering Delayed Auditory Feedback and Frequency Altered Feedback. It helps People Who Stutter increase their fluency with high-tech, quality fluency devices that are well-known, accepted and accessible.
SpeechEasy is a patented, stuttering inhibiting, prosthetic device with digital technology that delivers Delayed Auditory Feedback (DAF) and/or Frequency Altered Feedback (FAF). This feedback has the effect of inhibiting stuttering and facilitating fluency while SpeechEasy is worn. Based on “choral speech”, SpeechEasy creates the illusion of speaking in unison with someone else.

ISTAR currently offers two styles of SpeechEasy: the open-ear acoustics "Comfort Fit" (CF), and the practical and easy-to-handle, "Behind-The-Ear" (BTE).
