Illinois Phonetics & Phonology Lab




The lab has facilities for recording the airflows and pressures typically associated with speech. Using our mix of circumferentially-vented and pneumotach designs, you can record, calibrate, and analyze precision aerodynamic data.


You can use our pro-installation solid-state recorder along with a range of top microphones for high-quality recordings in our sound-attenuated audiometric booth. You can also record directly to a desktop computer when less precision is warranted.

Audiometric booth

The audiometric booth can be scheduled for recording sessions and perceptual experiments. Please contact a Lab Assistant to find out how to schedule a time.

Computers and printing

We have a mix of HP workstation and desktop machines to suit the various computing needs of faculty, graduate students, and undergrads.

Our HP laserjet printer is available for lab-related printing. Please help us reduce the lab's ecological footprint by printing only what is necessary and making a PDF of everything else!


An electroglottograph (EGG) is a non-invasive device that measures glottal activity (how tightly the vocal folds are touching and at what rate) with a very weak electric current. This can be used in conjunction with the aerodynamics equipment.


Electropalatography (EPG) measures contact between the tongue and palate during speech. This is done using a custom-fitted electropalate designed for each speaker. Data can be internally synchronized with acoustics or one other channel of physiological data.


The comptuers in the lab are equipped with a wide variety of tools for collecting and analyzing speech data, as well as for publishing the final product. These include:

  • Praat
  • E-Prime
  • Matlab
  • R
  • Open Office
  • CutePDF
  • LaTeX



Please contact a Lab Assistant if you would like to schedule a time for a practical demonstration of laboratory equipment or would like instruction in lab software. They're happy to help you out with any specific or general questions you have, or any problems you may have come across.


The Illinois Phonetics and Phonology Lab has initiated a series of mini-workshops. These brief tutorials are intended to familiarize you with the equipment and software in the Lab.

The mini-workshops will be informal. We hope students and faculty will feel free to drop in for part of the time or stay for the full session. Please contact a Lab Assistant for the current schedule.
