Broadly, Abigail is interested in elucidating how people are able to
categorize and understand speech sounds in order to effectively
communicate. Research questions are investigated using computational, phonetic,
and behavioral approaches.
Computational models of speech perception
What information is necessary in order for human listeners to correctly
categorize speech sounds? Are these cues combined and weighted according to
reliability? Abigail is interested in investigating these questions by
modeling the cognitive processes involved in speech perception. This section
of research involves corpus analysis, programing computational models in R,
and comparing multiple models of perception.
Results from this project will be presented at Psychonomics in November 2017.
Additionally, questions about what information is necessary to distinguish
the voicing feature of word initial stop consonants are addressed in a paper
to be submitted shortly.
Acoustic charactersitics of stop consonants
Though stop consonants are one of the most studied class of phonemes in the
English language, there has been no comprehensive review of possible acoustic
cues to stop consonant identity as there has been for vowels and fricatives.
In order to provide a complete dataset for further phonetic research, Abigail is
currently analyzing a large corpus of word initial stop consonants and summarizing
the relevant characteristics. Results from this research will be submitted to the
at the end of the summer 2017.
Cues at the level of individual tokens
For her thesis, Abigail will compare the collected phonetic data and computational
results to human listener performance on individual speech tokens. In this way,
it will be possible to analyze various models' ability to predict which phonemes
listeners will accurately categorize versus more ambiguous exemplars. Additionally,
individual tokens can be evaluated in terms of which cues are robust; that is,
do listeners rely mostly on one or two primary and highly reliable cues by
listeners or can multiple less robust cues be weighted during listener
categorization to reach an accurate result? This second possiblity relies on two
assumptions: (1) there are multiple cues present in each individual token and (2)
human listeners actively rely on this information during categorization. Answers
to these inquires will be pursued through behavioral experiments during the
2017-2018 academic year.
