CorpusCoder {AcousticNDLCodeR}

Codes a corpus for use with NDL with vector of wavefile names and a vector of TextGrid names provided

Description

Codes a corpus for use with NDL with vector of wavefile names and a vector of TextGrid names provided

Usage

CorpusCoder(Waves, Annotations, AnnotationType = c("TextGrid", "ESPS"),
  TierName = NULL, Dismiss = NULL, Encoding, Fast = F, Cores = 1,
  IntensitySteps, Smooth)

Arguments

Waves

Vector with names (and full path to if not in wd) of the wave files.

Annotations

Vector with names (and full path to if not in wd) of the TextGrid files.

AnnotationType

Type of annotation files. Suported formats are praat TextGrids (set to "TextGrid") and ESPS/Wavesurfer (set to "ESPS") files.

TierName

Name of the tier in the TextGrid to be used.

Dismiss

Regular expression for Outcomes that should be removed. Uses grep. E.g. "<|>" would remove <noise>,<xxx>, etc. Default is NULL.

Encoding

Encoding of the annotation file. It is assumed, that all annotation files have the same encoding.

Fast

Switches between a fast and a robust TextGrid parser. For Fast no "\n" or "\t" may be in the transcription. Default is FALSE.

Cores

Number of cores that the function may use. Default is 1.

IntensitySteps

Number of steps that the intensity gets compressed to. Default is 5

Smooth

A parameter for using the kernel smooth function provied by the package zoo.

Value

A data.frame with $Cues and $Outcomes for use with ndl or ndl2.
