MPI is short for Modify Phonation Intervals. A phonated interval (PI) is the elapsed time of a voiced unit of speech. Through extensive research and studies, we have found by manipulating or "modifying" the client's PIs, we can achieve durable and natural-sounding fluent speech in most clients who meet selection criteria.

The MPI program consists of three phases:

Establishment Phase

The goal of the Establishment Phase is for the client to achieve stutter-free and natural sounding speech within the clinic. This is accomplished by using specialized biofeedback software that is customized to the client by the Clinician. Clients typically achieve stutter-free speech by working on a regimented training schedule of 2-hour daily sessions lasting approximately 7-10 consecutive days.

Transfer Phase

The aim of the Transfer Phase is for the client to transfer the same stutter-free and natural sounding speech established within the clinic outside of the clinic. This is accomplished with real world speaking assignments (i.e. talking on the phone, to a person, etc) and recording the conversation with the MPI iOS application. The recordings which are automatically transferred to a server are evaluated by the Clinician to evaluate the client's progress. This phase is completed in approximately 5 weeks.

Maintenance Phase

The purpose of the Maintenance Phase is to maintain the progress achieved in the Transfer Phase while gradually reducing the client off of the speaking tasks. This phase is completed in approximately 9 months.
