The MPI-2 Stuttering Treatment application is a specially designed tool to provide professional treatment to individuals who stutter.

The Modifying Phonation Intervals (MPI-2) Stuttering Treatment Program is designed to teach mainly adolescents and adults who stutter to achieve generalized stutter-free and normal sounding speech by speaking with a reduced number of short intervals of phonation (PI=phonation interval). The program is a performance-contingent, biofeedback system that employs software (Android MPI-2 application) and hardware (Android phone or tablet and a throat microphone/accelerometer with single earpiece assembly). Targeted PIs are recorded from the surface of the speaker’s throat and their occurrence is automatically fed back to the speaker during treatment.

Special advantages of the MPI-2 are: its development by expert clinical researchers as a complete evidence-based treatment program – including establishment, transfer and maintenance of fluent speech, and its portability –which facilitates a significant role for the client in managing the treatment and the ability to practice newly learned speech patterns away from the clinic setting while being monitored by the software and/or the clinician.

A general description of the MPI-2 Stuttering Treatment Program, along with pre- and post-treatment speaking samples, as well as links to the research publications underlying development of the MPI-2, can be accessed at the MPI-2 website at http://www.mpi2.com.

In order to start the treatment program, the potential client needs to install the MPI-2 Stuttering Treatment Program application first on an Android phone or tablet, and then choose a clinician (via the “Find Clinician” button on the home screen). After the request has been received, the clinician will contact you to evaluate your condition and discussion additional details, including the cost of the clinician’s clinical services. All MPI-2 clinicians have earned master’s degrees as speech-language pathologists and the Certificate of Clinical Competence from the American Speech-Language Hearing Association and are also certified as MPI-2 clinicians.
