In congzhang365/rhythm.metrics: Analyse and Visualise Rhythm Metrics

Delta C & Delta V

Description

This function loads a dataframe as input and returns a dataframe containing the mean values and mean standard deviations of Delta C and Delta V.

Usage

delta_cv(df, cv_label, utterance_id, cv_duration)

Arguments

df:	a data frame containing cv_labels, utterance_id, and cv_duration values.
cv_label:	whether a segment is a C(onsonant) or a V(owel)
utterance_id:	each unique utterance should have a unique id
cv_duration:	the duration of C or V

Details

Delta C and Delta V are rhythm metrics based on Ramus, F., Nespor, M., & Mehler, J. (1999). Correlates of linguistic rhythm in the speech signal. Cognition, 73(3), 265-292.

⁠Delta C: SD of total C duration⁠ ⁠Delta V: SD of total V duration⁠

Value

delta_cv: a data frame containing the results of Delta C and Delta V values

df <- data.frame (cv_label  = c("c", "v", "c", "v","c", "v", "c", "v"),
                  utterance_id = c("utt_1", "utt_1", "utt_2", "utt_2",
                                   "utt_1", "utt_1", "utt_2", "utt_2"),
                  cv_duration = c(0.1, 0.8, 0.2, 0.5, 0.3, 0.3, 0.4, 0.7))
