Graduate student Yaqian Huang, a PhD candidate in our department, has been awarded a National Science Foundation Doctoral Dissertation Research Improvement Grant (Ling-DDRI, with Prof. Marc Garellek) for the project “Phonetics of period doubling.” The goal of the project is to study the production and perception of period doubling, an irregular voice quality with more than one pitch. Yaqian will characterize the articulatory and acoustic properties of period doubling, and determine how it affects pitch and tone perception.
