Nonspeaking (formerly called nonverbal) people, minimally speaking people, and people who have scripted and/or unreliable speech have great success communicating with S2C.
Autistic individuals, as well as people with motor sensory differences, use this as an effective, impactful communication method.
Here is a more detailed description of the type of nonspeakers we work with:
Nonspeaking: Someone who does not or rarely speaks with words but may produce sounds.
Minimally speaking: Someone who may be able to communicate simple requests like what they would like for a snack but are unable to use speech to communicate deeper or more complex thoughts such as their emotional experience.
Unreliably speaking: Someone who may say many words, such as phrases from a movie or the name of a restaurant, but are unable to access speech as an intentional means of communication.
