My current research is primarily on using speech-processing to design and develop medical and assistive technology applications.

• Speech Articulation Tools for Neuroscience Research
  This work is funded in part by NIH grant R44DC010104-03.
  • SpeechMark™ products are commercial software tools for detecting and identifying acoustic landmarks in digital speech waveforms. These tools are designed for speech scientists, linguists, signal processing engineers, and other researchers, to help them detect changes in the way speech sounds as a result of variations in speakers’ physical health, mental and emotional state, and stage of development.
