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.

Wiki

The Phonetics and Phonology Lab Wiki is a virtual encyclopedia of everything that goes on in the lab and how we do it. It may be accessed and edited by registered, active members of the Illinois Phonetics and Phonology community.

If you don't currently have a username and password and would like to access this resource, please contact Ryan Shosted

Once you are registered, you are strongly encouraged not only to read the wiki, but to edit existing pages and add your contribution in order to make the lab a more user-friendly and productive environment.

 

Data Acqusition

Aerodynamics

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.

Audio

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.

Electroglottography

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

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.

Ultrasound

Ultrasound can be used to better understand the position, shape, and movement of the tongue.

Tutorials

Individual Tutorial

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. The lab assistants are eager to help you out with any specific or general questions you have, or any problems you may have come across.

Mini-Workshops

The Illinois Phonetics & Phonology Lab runs 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.

Extramural

The University of Illinois at Urbana-Champaign is a leader in biomedical imaging, including real-time imaging of the human vocal tract. The image at right is a vector-graphic version of a single frame taken from a magnetic resonance "movie". The images were acquired at the Beckman Institute through the joint activities of Prof. Brad Sutton, Prof. Ryan Shosted, and their research groups.
