backdrop against which F0 is interpreted linguistically”. Tonal coherence within the prosodic phrase 73 However, Liberman and Pierrehumbert (1984) show that the major factors shaping the F0 contour are local ones, and, consequently, that it is not necessary to assume any time-dependent declination. The downward trend of F0 is explained by a combination of a final lowering effect and the usage of stepping accents. Since the sequences of stepping accents do not converge to zero, a nonzero… CONTINUE READING
Figure 4.3 Schematic illustration of how step size is related to how far above the reference or base line (the broken line) the F0 starting point (the first accent’s H12) is. The straight lines are drawn to demonstrate the resulting difference in F0 slope.
