• Comparing speaker-dependent and speaker-adaptive acoustic models for recognizing dysarthric speech

  Frank Rudzicz · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  This short ASSETS 2007 poster from Frank Rudzicz at the University of Toronto compares two strategies for building automatic speech recognition (ASR) acoustic models that work for people with dysarthria — a set of motor speech disorders that produces speech with high intra- and…

• The Ethnographically Informed Participatory Design of a PDA Application to Support Communication

  Rhian Davies, Skip Marcella, Joanna McGrenere, Barbara Purves · 2004 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets 04)

  This paper describes an ethnographically informed participatory design process for creating a PDA-based file management system to support communication for a person with aphasia. The research was conducted at the University of British Columbia with one primary participant, SM, a…

• A New Generation of Communication Aids under the ULYSSES Component-Based Framework

  Georgios Kouroupetroglou, Alexandros Pino · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper from the University of Athens introduces ULYSSES, a component-based software framework for building customisable AAC (Augmentative and Alternative Communication) devices. The core problem ULYSSES addresses is that AAC users have highly diverse and individual needs —…

• Capturing Phrases for ICU-Talk, a Communication Aid for Intubated Intensive Care Patients

  S. Ashraf, A. Judson, I. W. Ricketts, A. Waller, N. Alm, B. Gordon, F. MacAulay, J. K. Brodie, M. Etchels, A. Warden, A. J. Shearer · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets 02)

  This paper describes the vocabulary gathering methods used for ICU-Talk, a three-year multidisciplinary project at the University of Dundee and Ninewells Hospital that developed an augmentative and alternative communication (AAC) aid specifically for intubated intensive care…

• ICU-Talk, A Communication Aid for Intubated Intensive Care Patients

  F. MacAulay, A. Judson, M. Etchels, S. Ashraf, I. W. Ricketts, A. Waller, J. K. Brodie, N. Alm, A. Warden, A. J. Shearer, B. Gordon · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets 02)

  This paper describes ICU-Talk, a computer-based communication aid developed specifically for intubated patients in hospital intensive care units (ICUs) who are temporarily unable to speak due to breathing tubes inserted through their mouth or throat. The three-year…

• A Predictive Blissymbolic to English Translation System

  Annalu Waller, Kris Jack · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper addresses a fundamental limitation of Blissymbolics in electronic AAC: while Blissymbol users can compose messages by selecting symbols, converting those symbol sequences into grammatically correct English is non-trivial. Blissymbolics is a semantic graphic language…

• Multimodal Input for Computer Access and Augmentative Communication

  Alice Smith, John Dunaway, Patrick Demasco, Denise Peischl · 1996 · Proceedings of the Second Annual ACM Conference on Assistive Technologies (Assets '96)

  This paper from the University of Delaware describes a research project exploring the integration of speech recognition with head-pointing as a multimodal input method for people with physical disabilities who cannot use standard keyboards and mice. The authors frame the problem…

• Enhancing Scanning Input with Non-Speech Sounds

  Stephen A. Brewster, Veli-Pekka Raty, Atte Kortekangas · 1996 · Proceedings of the Second Annual ACM Conference on Assistive Technologies (Assets '96)

  This paper proposes adding structured non-speech sounds (earcons) to scanning input systems used by people with severe motor disabilities who can only operate a single switch. Scanning input works by sequentially highlighting items in a grid; the user presses their switch when…

• A communication tool for people with disabilities: lexical semantics for filling in the pieces

  Kathleen F. McCoy, Patrick W. Demasco, Mark A. Jones, Christopher A. Pennington, Peter B. Vanderheyden, Wendy M. Zickus · 1994 · Proceedings of the First Annual ACM Conference on Assistive Technologies (Assets '94)

  This paper presents a prototype communication tool designed to reduce the input burden for people with severe speech and motor impairments (SSMI) who use word-based augmentative communication systems. The core problem addressed is that even with word-prediction and word-based…

• The application of spatialization and spatial metaphor to augmentative and alternative communication

  Patrick Demasco, Alan F. Newell, John L. Arnott · 1994 · Proceedings of the First Annual ACM Conference on Assistive Technologies (Assets '94)

  This paper presents a collaborative project between the University of Delaware and the University of Dundee investigating how spatialization and spatial metaphors from mainstream HCI research can improve interfaces for augmentative and alternative communication (AAC). The…
