Auditory feedback in speech motor control of timing

During my postdoc, I have been working with the altered auditory feedback paradigm to examine the role of auditory feedback in monitoring and controlling temporal aspects of speech. We have found that speakers respond to shortened vowels by lengthening them, and may also be compensating for lengthened consonants with changes in the vowel as well. This provides support for previous arguments that speakers and listeners attend to and control proportional durations, rather than absolute durations.

Tone to segment alignment

In my dissertation, I used the lens of lexical tone to examine the relationship between phonological association and phonetic realization. I built on work I did for my first qualifying paper, which explored the concept of an articulatory TBU, this time focusing on cross- and within-language variation in peak timing, working with acoustic and articulatory data from Central Thai and Serbian. I argue for an articulatory approach to the TBU, where both abstract association and concrete realization can be derived from coordinative relationships.‚Äč

Stress, moras, and timing

Stress as a linguistic reality is a somewhat controversial topic, and I am interested in the interplay of stress, weight, and linguistic pitch. In some of my work outside of tone I have examined the case of northern dialects of Finnish, which display extra lengthening of the (not necessarily stressed) second mora, along with various other phenomena that affect the timing of the second mora position.

Building representations

The last area that I am interested in is the acquisition and building of representations. How do learners acquire representations, and what stages do they go through on their way? How do we move from phonetic (acoustic) artefacts to fully phonologized gestures or features? How can these stages inform us on adult representations? I am particularly interested in tonogenesis and am currently conducting research on Burmese, which has a complex interplay between laryngeal and tonal phenomena.
