“…A means of reducing the effort required in communication is obviously called for. Some savings have been obtained in scanned matrix systems by the use of letter digram and trigram frequencies to vary the layout of the matrix, hence reducing the switch selections (Heckathorne & Childress, 1983). A more powerful technique, however, would be to use an approach which reduced the number of character selections necessary to enter a given piece of text.…”

This paper describes a communication aid and keyboard emulator which has been developed at Dundee University. The device, Predictive Adaptive Lexicon (PAL), exploits the redundancy in natural language to reduce the key pushes or character selections necessary during the composition of text. Word predictions are offered to the user from a dictionary, and if one of these is selected the word is completed by PAL. PAL adapts to the user's vocabulary by automatically capturing words which are not already in the dictionary. These will thereafter be offered in prediction lists. A reduction in the number of character inputs necessary to enter any given text of over 50% is possible when using PAL, giving the user a considerable saving in time and effort.

“…There are two main concepts that have to be taken into account when analysing communication systems, articulateness and fluency [37]. An input system has high articulateness if there is always at least one option fitting the user needs which can be selected among all offered proposals.…”

Text prediction is one of the most widely used techniques to enhance the communication rate in augmentative and alternative communication. Prediction systems are traditionally used by people with disabilities (e.g. people with motor and speech impairments). However, new applications, such as writing short text messages via mobile phones, have recently appeared. A vast amount of heterogeneous text prediction methods and techniques can be found in literature. Their heterogeneity makes it difficult to understand and compare them, in order to select the most convenient technique for a specific design. This paper presents a survey on text prediction techniques with the intention to provide a systematic view of this field. Prediction applications and related features, such as block size, dictionary structure, prediction method, user interface, etc., are examined. In addition, prediction measurement parameters and published results are compared. A large number of factors that may influence prediction results, including the acceptance of the system by the users, are reviewed, and their influence on the performance and usability of the system is discussed.

“…All current communication devices (e.g., see [4,5]) require encoded knowledge in one form or another to make message generation possible. In constrast to state-of-the-art communication devices, the KMGS stores knowledge of the message "units" (%English sentences), rather than just the basic message elements (English words or letters).…”

An intelligent communication device is being developed to assist the nonverbal, motor disabled in the generation of written and spoken messages. The device is based upon a knowledge base of the grammatical rules and message elements. A "belief" reasoning scheme makes use of highly uncertain speech recognition information in combination with the embedded knowledge to optimize the process of message search.This paper focuses on the integration of that speech information. Experimental testing of a prototype system to assess the effects of speech evidence is discussed.
