If you're referring to the survey: I only know about my own experiences stuttering; this survey will help me to make design decisions based on a more holistic set of perspectives. If you're referring to the device: The device will help you to monitor various things in your body which cause stuttering. For example, breathing into your stomach as opposed to your chest reduces tension build up in your vocal chords. I can monitor this dichotomy using biosensors and show it to you in a visual form. This will help you to become more aware of your body and will enhance your experience when doing vocal exercises.
