Kellermann et al. Slots and fillers have two purposes in SchemaTalk. First, they enable the user to prestore related words or phrases. Second, a slot can be associated with a particular location in a sentence to create a sentence template. When a sentence template is selected, the list of fillers for a given slot is displayed.
Sentence templates reduce the number of selections required to produce a sentence.
They also reduce the need to store and scroll through long lists of sentences, had each template filler been stored separately. Dialog boxes containing lists of MOPs and scenes appear when called, while sentences for the current scene or fillers for the current slot are displayed as a scrolled list in the main window. In order to make a preliminary evaluation of the SchemaTalk approach, a series of mock interviews was carried out. Two subjects participated, one with physical and speech impairments, and one without. We refer to them here as S1 and S2.
