• 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…

• Individuality-Preserving Voice Conversion for Articulation Disorders Using Phoneme-Categorized Exemplars

  Ryo Aihara, Tetsuya Takiguchi, Yasuo Ariki (2015) — ACM Transactions on Accessible Computing

  This paper presents a voice conversion system designed to improve speech intelligibility for people with articulation disorders resulting from athetoid cerebral palsy, while critically preserving the speaker's voice individuality. Cerebral palsy affe…
