fell short of significancep = 0.06
This analysis revealed a significant proportion of temporal cases when vocal acoustics were measured by multidimensional clustering (3D acoustics, p <0.05 after Bonferroni correction for multiple comparisons indicated by cross in Figure 2d ), but the same measure fell short of significance when the three acoustic parameters were considered individually ( p = 0.06–0.24 after Bonferroni correction).
