Matthew C. Kelley, Benjamin V. Tucker
Research on speech perception and lexical access often uses the activation and competition metaphor to describe the process of spoken word recognition. One way of expressing competition associated with a given word is its phonological neighborhood density, which is a calculation of similarity....

Listener Discrimination Between Age Differences in Two Speakers: A comparison task involving recordings of the voices of Terry Gross and Ira Glass from different years
Download2023-05-04
Often when listeners hear a speaker, they have an impression of the age of the speaker. The present research seeks to determine how well listeners can identify a speaker’s age when provided with two different recordings from one speaker. Previous research has asked participants to place a...

MALD MFCC subset
2019-10-01
A subset of the Massive Auditory Lexical Decision stimuli. They are represented as sequences of MFCCs with delta and delta-delta coefficients. There are also associated label files so that the data can be used for machine learning purposes, though they are force-aligned labels and not...

Although most auditory lexical decision experiments are performed in a laboratory setting, humans tend to communicate in uncontrolled and noisy environments. We investigated, indirectly, the impact of noise and other distractions on lexical processing. The present study used a subset of words...

Measuring the dispersion of density in head and neck cancer patients' vowel spaces: The vowel dispersion index
Download2019-10-16
Matthew C. Kelley, Daniel Aalto
The present study introduces a measure of the dispersion of density throughout the vowel space, which we refer to as the vowel dispersion index. The vowel dispersion index is based on calculating the total variation of the density values in Story & Bunton’s (2017) convex hull representation of...

Fall 2018
Neotropical dry forests are severely threatened by human activities such as agricultural expansion, tourism, cattle ranching, logging, and an increase in human settlements. However, despite these trends, some countries have experienced forest recovery. Costa Rica is a clear example of this...

Perception and timing of acoustic distance
2021-11-06
Matthew C. Kelley, Benjamin V. Tucker
The notion of acoustic distance figures into many aspects of phonetics, including phonological neighborhoods. A measurement of word-level acoustic distance useful for cognitive modeling must account for two aspects of perception: listener sensitivity to acoustic differences and the duration...

Prosodic focus marking in clefts and syntactically unmarked equivalents: Prosody–syntax trade-off or additive effects?
Download2021-01-01
Two experiments quantitatively investigated the interaction of prosody and syntax in marking focus in English. A production study with 28 participants (analyzing 919 utterances) found that the acoustic marking of subject focus vs broad focus, induced through a preceding context question, was...
