ISAAC'96:

One of the main issues when choosing an Augmentative and Alternative Communication System is its adaptability to the needs of the end user. A wide range of systems with different user interfaces can nowadays be found on the market. However, their cost is too high, mainly because of the small quantities produced. This paper presents a prototype voice-output AAC aid whose modularity enables the connection of different user interfaces, keeping the same AAC hardware core, minimising development and production costs.
