The NeuroSpeech Lab is a research laboratory located in the Department of Speech and Hearing Science (901 S. Sixth Street) at the University of Illinois. It was established in April 2007 under the direction of Dr. Torrey Loucks. The primary activities in the lab have been supported by various external and internal funding sources (see curriculum vitae of Dr. Loucks). The laboratory consists of a 400 sq. ft. sound-treated room for speech movement studies and a separate sound booth for auditory feedback studies.

The research equipment available in the lab include:

  • Auditory processing workstations for altering feedback with automated routines. Hardware processors from Tucker-Davis Technologies, Eventide and Symbolic Sound are used for studies of delayed auditory feedback, pitch altered feedback, tone matching and formant frequency alterations. High quality amplifiers, headphones, and microphones available for each workstation.
  • Movement recording system: 4 motion tracking cameras manufactured by Motion Capture Inc., are used to record speech and non-speech movements.
  • Fine force transducers: Transducers for recording fine force control of the tongue, lips, wrist and fingers are available for motor control studies.
  • Computerized Speech Lab (CSL) from Kay Pentax.
  • Speech air flow / air pressure recording system from Glottal Enterprises (Clinical Instrumentation Lab).
  • Electroglottograph system from Glottal Enterprises (Clinical Instrumentation Lab).
  • Phsyiological signal recording (16 channel Powerlab and 16 channel Windaq systems).
