WRAP LAB

Speech Perception and Language Lab at Villanova University

Welcome to the Word Recognition & Auditory Perception Lab (WRAP Lab)! Our group studies how human listeners recognize speech and understand spoken language. Investigating language processing as it happens is central to our approach, and we use a combination of computational, cognitive neuroscience, and behavioral techniques to study these processes.

Here's what we've been up to lately

New Paper on Age-Related Changes in Speech

In a paper in press at Language and Speech, Dr. Toscano and Dr. Charissa Lansing from the University of Illinois investigated how cue weights in speech perception change with age. Young adults (18-30 years old) use both voice onset time (VOT) and f0 as cues to voicing. Older adults (approx. 30-50 years old) do as well, but they rely more on f0, even though it is a less reliable cue than VOT. This shows that listeners continue to reweight acoustic cues in speech across the lifespan. Read the article here.

Student Receives Graduate Travel Award

Earlier this summer, graduate student Abby Benecke was among the 2017 recipients of the Graduate Travel Award from the Psychonomic Society for her research in "Classification of English Stop Consonants: A Comparison of Multiple Models of Speech Perception."

New Paper on Gradient Acoustic Information and Referential Interpretation

Dr. Toscano recently published a paper entitled "Gradient acoustic information induces long-lasting referential uncertainty in short discourses" with Dr. Sarah Brown-Schmidt of Vanderbilt University in Language, Cognition, and Neuroscience. The study uses the visual-world eye-tracking paradigm to show that listeners maintain activation of referents in a scene based on fine-grained acoustic information in pronouns over a multi-word delay. Check out the article here.

New Paper on Audiovisual Speech Perception

Post-Doctoral fellow Laura Getz along with grad students Elke Nordeen and Sarah Vrabaic recently published a paper entited, Modeling the Development of Audiovisual Cue Integration in Speech Perception."

We know that adult speech perception is generally enhanced when information is provided from multiple modalities (i.e., when you can both hear the speaker and see their lip movements). In contrast, infants do not appear to benefit from combining auditory and visual speech information early in development. How, then, do listeners learn how to process auditory and visual information as part of a unified signal? In this paper, we used a computational modeling approach to simulate the developmental time course of audiovisual speech integration. We find that this domain-general statistical learning technique provides a developmentally-plausible mechanism for understanding speech perception development.

Student Receives Summer Fellowship

Grad student Abby Benecke has received a summer fellowship from the Graduate College at Villanova. Way to go, Abby!

Her proposal, "Redundancy and variability in speech: Listeners' use of token-level phonetic cues," will use computational modeling approaches to investigate what acoustic features are necessary for accurate speech perception of English stop consonants (/b,d,g,p,t,k/), as well as examine whether there are multiple informative cues in each individual speech sounds.
