Source: R/fragmentAudio.R
fragmentAudio.Rd

This is a version of getSoundFragments that can have a dataframe of matches piped into it.

Usage

fragmentAudio(
  matches,
  sample.rate = NULL,
  path = "",
  no.progress = FALSE,
  start.column = Line,
  end.column = LineEnd,
  labbcat.url = NULL
)

Arguments

matches

A dataframe returned by getMatches or getAllUtterances, identifying the results to which acoustic measurments should be appended.

sample.rate

Optional sample rate in Hz - if a positive integer, then the result is a mono file with the given sample rate.

path

Optional path to directory where the files should be saved.

no.progress

TRUE to suppress visual progress bar. Otherwise, progress bar will be shown when interactive().

start.column

The column of matches containing the start time in seconds.

end.column

The column of matches containing the end time in seconds.

labbcat.url

URL to the LaBB-CAT instance (instead of inferring it from matches).

Value

matches with the acoustic measurements appended as new columns.

Details

It gets fragments of audio from LaBB-CAT, as wav files.

## Get a 22kHz sample rate wav file for each matched utterance
the.wavs <- the.tokens |> fragmentTranscripts(sample.rate = 22050)
