vocaldia (version 0.8.4)

getSampledVocalMatrix: getSampledVocalCountMatrix: generate vocalisation diagrams

Description

Generate a probabilistic vocalisation diagram through 'sampling'.

Usage

getSampledVocalMatrix(df, ...)

Value

a vocaldia object, consisting of a vocalisation matrix (vocmatrix) where cell <m,n> contains the transition probability from node n to node m, and a table of prior probabilities (stationary distribution) per node.

Arguments

df

a data frame consisting, minimally, of a column for vocalisation/pause start times, a column for end times, and a column identifying the speaker, speaker role or 'Floor' (for silences).

...

general parameter to be passed to getSampledVocalCountMatrix

Details

A vocalisation diagram (vocaldia) is a representation of a dialogue as a Markov process whose cell <m,n> contains the transition probability from node n to node m).
