Abstract
In consonant‐vowel transitions, it is well known that the frequency of the second formant at the onset of voicing (F2onset) is linearly correlated with the frequency of the second formant in the middle of the vowel (F2vowel). This correlation, which holds across the vowel contexts for a given consonant place of articulation (POA), is characterized by a regression line (locus equation) with a slope and y‐intercept that depend on the consonant POA. Furthermore, for a given POA, slopes and y‐intercepts of collections of locus equations are inversely related. The cause of this inverse relation has not yet been explained. In this presentation, we will show that the inverse relation implies that the F2vowel vs. F2onset coordinate system is most naturally described as a mathematical translation away from the origin, and that the size of the translation is a function of the POA and of the second and third subglottal resonances.
