• Humming Control Interface for Hand-held Devices

  Sook Young Won, Dong-In Lee, Julius Smith · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This paper from Stanford University presents a control-by-humming interface that allows hands-free operation of portable devices such as cell phones and music players through subvocal humming detected by a Bluetooth-connected insertion earphone/microphone. The system converts…

• Demo of VJ-Voicebot: Control of Robotic Arm with the Vocal Joystick

  Brandi House, Jon Malkin, Jeff Bilmes · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This demonstration paper from the University of Washington presents VJ-Voicebot, a system that allows individuals with motor disabilities to continuously control a 5 degrees-of-freedom robotic arm using non-verbal vocal sounds. The system builds on the Vocal Joystick (VJ)…

• VoiceDraw: a hands-free voice-driven drawing application for people with motor impairments

  Susumu Harada, Jacob O. Wobbrock, James A. Landay · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Harada, Wobbrock, and Landay's Assets '07 paper introduces VoiceDraw, a hands-free digital painting application for people with severe motor impairments that uses *non-speech* vocalisations — continuously-held vowel sounds and short consonant clicks — rather than discrete speech…

• 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…
