Dan is currently working on experiments examining how glides and high vowels differ phonetically. He is particularly interested in how to differently prioritize acoustic versus articulatory targets and feedback.
He uses an altered feedback paradigm to see how these segments respond to altered real-time auditory feedback with unaltered somatosensory feedback, and has found that participants compensate more for vowels than glides either by adjusting formants or, unexpectedly, by lengthening the vowel to be longer than the applied alteration.
Dan also works with the Burmese language. He has conducted field phonological examination and production experiments with native speakers and found evidence for a tonally-based weight distinction within the major syllables
