fragmentAudio: Gets sound fragments from 'LaBB-CAT'.

Description

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
)

Value

matches with the acoustic measurements appended as new columns.

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).

Details

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

Examples

Run this code

if (FALSE) {
## Get all tokens of "the"
the.tokens <- getMatches(labbcat.url, "the")
## Get a 22kHz sample rate wav file for each matched utterance
the.wavs <- the.tokens |> fragmentTranscripts(sample.rate = 22050)
}
