Lingraphica

A commercially available computerized visual communication system designed to help people with aphasia communicate through icon-based sentence construction. Lingraphica provides a vocabulary of purpose-designed icons that users can arrange to form phrases and sentences, with the system translating the arrangements into spoken output. While effective for basic communication, Lingraphica and similar systems are limited by their fixed icon vocabularies, typically containing only a few thousand symbols, which restricts users from discussing topics outside the predefined set.
