The trajectory for center of gravity, for example, significantly differs between z11 and most of the other six variables. Overall kurtosis is significantly different when z11 is manipulated, compared to, for example, z26 and z29. Similarly, while z74 does not significantly attenuate amplitude of [s], it significantly differs in skew trajectory of [s]. The main function of z74 is thus likely in its control of spectral properties of frication of [s] (e.g. skew).
