Measures of vowel overlap explore the acoustic similarity between proposed and existing vowel categories. They typically compare F1 and F2, and sometimes duration. In the present study, we investigate four methods of quantifying vowel overlap: the spectral overlap assessment metric (Wassink,...

Multiple measures of vowel overlap have been proposed that use F1, F2, and duration to calculate the degree of overlap between vowel categories. The present study assesses four of these measures: the spectral overlap assessment metric [SOAM; Wassink (2006). J. Acoust. Soc. Am. 119(4), 2334–2350],...

Forced alignment is increasingly used in phonetics to automatically produce boundaries between words and phones. These boundaries can have significant errors and are often only placed at some predetermined time interval, like every 10 ms. We discuss some potential remedies to these difficulties...

Acoustic absement files
2021-01-01
Matthew C. Kelley, Benjamin V. Tucker
These files contain acoustic absement and acoustic distinctiveness calculations for the words in the Massive Auditory Lexical Decision database. These files accompany the "Using acoustic distance and acoustic absement to quantify lexical competition" article in the Journal of The Acoustical...

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....

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...

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...

bBoiA sizable number of phonetic and psycholinguistic experiments have been conducted to investigate the recognition of real words. From this work, researchers have found that various characteristics of lexical items affect the recognition process, such as lexical frequency, phonotactic...

Matthew C. Kelley, Benjamin V. Tucker
The files contained in this deposit are the supplementary files for the paper "A Comparison of Four Vowel Overlap Measures". The files contained are the code for the vowel overlap measures (soam.R, aposteriori.R, voach.R), the code for plotting the vowel overlap measures (plot.soam.R,...

Supplementary materials and data for "Perception and timing of acoustic distance"
2023-01-21
Matthew C. Kelley, Benjamin V. Tucker
The files in this ZIP archive are supplementary materials for "Timing and perception of acoustic distance". There are three main subfolders: 1) "distance_rating" - contains the files to reproduce the distance rating task analysis 2) "duration_discrimination" - contains the files to reproduce the...
