As the figure shows, the pattern seen in Figure 17 was borne out on the whole in the stimuli with theme phrases.
the theme phrases for the APML voice had an f0 drop of 90 Hz on average from the adjective to the noun, whereas the ALL voice only had an f0 drop of 50 Hz, a significant difference (t-test, 1-tailed, t 22 = 2.60, p = 0.008).
