In interviews with speech pathologists and sufferers, we learned that stuttering depends on the perception of the listener and the quietness of the surroundings. Speech therapists use systematic desensitization, a gradual replacement of fear with relaxation training to counter condition. Competitors like Mimerse, CleVR, and SimSensei require supervision or lack customization. Instead we use AI to track training progress and physiological state, creating a desensitization regiment customized for individual users in training speed and difficulty.

In the program, the user is first greeted by the AI, who asks her for the relaxation atmosphere (forest or beach) and activity (slow reading or deep breathing) she prefers. Using natural language comprehension, the AI loads the selected scene, then asks the user for her level of anxiety, using this info to run the simulation scene where she practices speech. It can be easy (no people, quiet room) or various degree more difficult (people, noisy).
