Publikováno v:
Journal of Speech, Language, and Hearing Research. 61:1104-1117
Purpose The purpose of this study was to examine the effect of speech intensity on acoustic and kinematic vowel space measures and conduct a preliminary examination of the relationship between kinematic and acoustic vowel space metrics calculated fro
