  "Description": "Calculates and visualises speech rhythm and timing\nmetrics. The 'rhythm.metrics' package provides a standardised\nworkflow to compute common metrics including Delta C, Delta V,\nVarcoC, VarcoV, the percentage of vocalic intervals (%V), and\nboth raw and normalised Pairwise Variability Indices (rPVI,\nnPVI). It includes functions for calculating and visualising\nthese measures to facilitate cross-linguistic and developmental\nrhythm research. Delta C, Delta V, and %V measures are based on\nRamus et al. (1999) <doi:10.1016/S0010-0277(99)00058-X>; VarcoC\nand VarcoV measures are based on Dellwo (2006, ISBN:\n9783631554777); and rPVI-C and nPVI-V are based on Grabe & Low\n(2002) <doi:10.1515/9783110197105.2.515>.",
