Corpus Studies in Word Prediction
This paper from the University of Delaware investigates how the choice and combination of training corpora affects the performance of statistical word prediction systems for Augmentative and Alternative Communication (AAC) devices. The fundamental ch…

Loudmouth: Modifying Text-to-Speech Synthesis in Noise
This short paper from Northeastern University presents Loudmouth, a modified text-to-speech synthesizer that emulates the Lombard effect — the natural way humans adjust their speech in noisy environments — to improve synthesized speech intelligibilit…

Indirect Text Entry Using One or Two Keys
This paper introduces a new descriptive model for indirect text entry — text composition methods where the number of input devices (switches) is significantly smaller than the number of selectable characters. This is the primary text entry paradigm f…

User Modeling for Individuals with Disabilities: A Pilot Study of Word Prediction
This short paper describes the development of user models that predict how word prediction (WP) systems affect text entry performance for individuals with disabilities. The research addresses a practical clinical problem: clinicians who assess assist…

The Information-Theoretic Analysis of Unimodal Interfaces and their Multimodal Counterparts
This paper applies Shannon Information Theory to formally analyse and quantify the hypothesised benefits of multimodal interfaces over unimodal ones, with particular focus on Augmentative and Alternative Communication (AAC) devices such as Voice Outp…

Semantic Knowledge in Word Completion
This paper proposes an integrated word-completion system that combines semantic knowledge with traditional n-gram statistical models to produce more contextually appropriate predictions for users with linguistic or physical disabilities. Standard wor…

A System for Creating Personalized Synthetic Voices
This paper presents the ModelTalker Voice Creation System, a tool that enables individuals to create personalized synthetic voices with unrestricted vocabulary for use in augmentative and alternative communication (AAC) devices. The system addresses …

visiBabble Demo
This paper presents a demonstration of visiBabble, a computer-based system designed to encourage and reinforce pre-speech vocalizations in infants at risk of being nonspeaking due to neurological or oral/motor impairments. The system consists of a no…

visiBabble for Reinforcement of Early Vocalization
This paper presents visiBabble, a real-time system that detects syllable-like vocalizations in infant babbling and responds with brightly coloured animations as visual reinforcement. The system targets infants at risk for speech impairments due to co…
