Dr. Wei-rong Chen (Haskins Laboratories, Yale University) presents:
Articulatory correlates of vowel intrinsic fundamental frequency
The vowel-intrinsic fundamental frequency (IF0), a general tendency that high vowels have higher F0 than low vowels, has been studied for more than 100 years, yet the true biomechanism underlying IF0 is still in debate. Few studies have investigated the articulatory correlates of IF0, but their results are inconsistent. We extended such investigation by analyzing the articulatory data in two large corpora with 40 American English speakers. Our results showed that both tongue and jaw positions correlates with IF0, but further analyses (i.e., step-wise regression and data-subsetting analyses) revealed that the jaw contribution is significantly greater than the tongue contribution to IF0. More discussions about hypothesis testing will be given.
