Multi Chat 15 is offered in a Student, Adolescent, and Adult version of NOVA chat 8.
There are multiple forms of communication available in this program: sentences, phrases, individual words, recordings for story-telling, and visual scenes.
Chat Power 30 is a modified version of Chat Power24, but it includes an extra column on every page.
The extra column includes designated buttons for clear, delete word, smart period, and plural —s.
Word completion and logical next words are used, and the "grammar" function provides morphological endings to verbs, nouns and adjectives.
