Fig. 7.
Two paired stimuli illustrating the different intonation conditions in the experiment. These are the voice spectrograms with their fundamental frequency contours (blue line). Top: the fundamental frequency F0 (Hz) of the final word rises, thus forming a question (Valerie is driving her car to work?); bottom: the fundamental frequency F0 (Hz) of the final word falls, thus forming a statement (Valerie is driving her car to work.). Figures were created using the PRAAT software (Boersma, 2001). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
