In these videos, the glottal pulse rate (GPR) changes from 137 to 183 Hz, holding syllable type and VTL fixed.

The first video presents the normalized version of the auditory image in cycles format.

The syllables in this example are from the database described in Vestergaard et al. (2009), Table 1. Specifically, they are the /da/ from spoke 1, point 7 (GPR, 137 Hz; VTL, 15.8 cm), and the /da/ from spoke 4, point 4 (GPR, 183 Hz; VTL, 15.6 cm).
