rPVI C

Description

This function loads a dataframe as input and returns a dataframe containing the mean values of rPVI of consonants.

Usage

rpvi_c(df, c_label, utterance_id, cv_duration)

Arguments

df:	a data frame containing cv_labels, utterance_id, and cv_duration values.
c_label:	a string to filter the consonants, e.g. c_label = 'C' or c_label = 'consonant'
utterance_id:	each unique utterance should have a unique id
cv_duration:	the duration of C or V (only the values for vowels will be used)

Details

rPVI C is a rhythm metrics based on Grabe, E., & Low, E. L. (2002). Durational variability in speech and the rhythm class hypothesis. In Laboratory phonology 7 (pp. 515-546). De Gruyter Mouton. It calculates the sum of the absolute differences between pairs of consecutive consonantal intervals divided by the number of pairs in the speech sample.

Value

rpvi_c: a data frame containing the mean values of rpvi for consonants
