Lingraphica is an example of what kind of system?

• A. Augmentative communication system
• B. Language translation device
• C. Sensor-based input device
• D. Voice recognition system

Answer: (A)

Lingraphica demonstrates an augmentative communication system, a type of AAC designed for people who have limited or no speech to convey messages. It provides an electronic vocabulary of symbols and words that the user can select, which then generates spoken output. This supports functional communication and participation in daily activities, such as conversation, learning, and social interaction, especially after language impairments like aphasia. It’s not a language translation device, which would convert between languages; it’s not primarily a sensor-based input device, which would gather environmental data; and it’s not a voice recognition system, which interprets spoken input.
