Figure 3.

Hypothesized effects on relative fundamental frequency (RFF) in semitones (ST) of longitudinal vocal fold tension (panel A), abductory factors (panel B), and aerodynamic factors (panel C) for individuals with typical vocal fold tension (black solid line), increased baseline longitudinal tension (blue dashed line), and increased baseline longitudinal and transverse tension (red dotted line). The hypothesized summed effect of panels A, B, and C is depicted in panel D, the hypothesized RFF for all offset and onset vocal cycles.
