The PEP Lab is used by faculty and students in the linguistics department to investigate issues in phonetics, laboratory phonology, and sociophonetics. Equipped with a sound-attenuated booth, digital recording equipment, nasometry and perception booths, the lab provides tools for investigating the acoustic characteristics of speech. A modular ultrasound unit is available for teaching purposes.

The PEP lab hosts regular PEP Lab meetings.

Ultrasound images provide real time information about the shape of the tongue body at different stages in articulation.		Acoustic analysis is important for both perception and production studies. Members of the PEP lab have designed lexical decision, AX discrimination, matched guise, and picture learning tasks in order to study issues ranging from second language acquisition to loanword phonology to accommodation between speakers of different dialects.
