Description of rhythm metrics applied in this study (as detailed in Liss et al. (2009, p. 1339)).

Variable	Description
%V	Percent of utterance duration composed of vocalic intervals
∆V	Standard deviation of vocalic intervals.
∆C	Standard deviation of consonantal intervals.
VarcoV	Standard deviation of vocalic intervals divided by mean vocalic duration (×100).
VarcoC	Standard deviation of consonantal intervals divided by mean consonantal duration (×100).
VarcoVC	Standard deviation of vocalic + consonantal intervals divided by mean vocalic + consonantal duration (×100).
nPVI-V	Normalized pairwise variability index for vocalic intervals. Mean of the differences between successive vocalic intervals divided by their sum (×100).
rPVI-C	Pairwise variability index for consonantal intervals. Mean of the differences between successive consonantal intervals.
nPVI-VC	Normalized pairwise variability index for vocalic + consonantal intervals. Mean of the differences between successive vocalic + consonantal intervals divided by their sum (×100).
rPVI-VC	Pairwise variability index for vocalic and consonantal intervals. Mean of the differences between successive vocalic and consonantal intervals.
