Aligned Corpus Toolkit

Description

The Aligned Corpus Toolkit (act) is designed for linguists that work with time aligned transcription data. It offers functions to import and export various annotation file formats ('ELAN' .eaf, 'EXMARaLDA .exb and 'Praat' .TextGrid files), create print transcripts in the style of conversation analysis, search transcripts (span searches across multiple annotations, search in normalized annotations, make concordances etc.), export and re-import search results (.csv and 'Excel' .xlsx format), create cuts for the search results (print transcripts, audio/video cuts using 'FFmpeg' and video sub titles in 'Subrib title' .srt format), modify the data in a corpus (search/replace, delete, filter etc.), interact with 'Praat' using 'Praat'-scripts, and exchange data with the 'rPraat' package. The package is itself written in R and may be expanded by other users.

Package options

The package has numerous options that change the internal workings of the package.Please seeact::options_show and the information given there.

Examples

Slots

name

Character string; Name of the corpus.

transcripts

List of transcript objects; Each annotation file that has been load is stored in this list as a transcript object.

Vector of character strings; Only files matching this regular expression will be imported into the corpus.

import.names.exclude

Vector of character strings; Files matching this regular expression will be skipped and not imported into the corpus.

import.names.modify

List; Options how to modify the names of the transcript objects when they are added to the corpus. These options are useful, for instacne, if your annotation files contain character sequences that you do not want to include into the transcript name in the corpus (e.g. if you regularly add a date to the file name of your annotations files as 'myFile_2020-09-21.TextGrid').

Usage

import_eaf(filePath = NULL, fileContent = NULL, transcriptName = NULL)

Arguments

Details

Please note:

• 'ELAN' offers a variety of tier types, some including dependencies from other tiers. Therefore not all annotations do actually have a time value. Missing values will be detected in the superordinate tier or will be interpolated. You will not be able to recognize interpolated values in the annotations.

• Please also note that dependencies between tiers in you .eaf file are not reflected in the transcript object within the act package.

Value

Arguments

Details

Imports the contents of a 'EXMARaLDA' .exb file and returns a transcript object.The source is either the path to a .exb file or the contents of a .exb file obtained from the@file.content of an existing transcript object.If you pass 'fileContent' you need to pass 'transcriptName' as parameter, too.

Please note:

• 'EXMARaLDA' allows for empty time slots without a time values. Missing values will be interpolated during the import. You will not be able to recognize interpolated values in the data.

• Meta data for tiers (such as the display name etc.) will not be imported.

• Media files are referenced not by their path but only as file names in .exb files. The names will be imported but will not work as paths in act.

Import a single 'rPraat' TextGrid object

Description

This function is to create compatibility with therPraat package.It converts a 'rPraat' TextGrid object into an act transcript object.

Usage

import_rpraat(rPraatTextGrid, transcriptName = NULL)

Arguments

Details

Please note:

• Time values of annotations in TextGrids may be below 0 seconds. Negative time values will be recognized corretly in the first place. When exporting transcript object to other formats like 'ELAN' .eaf, 'EXMARaLDA' .exb ect. annotations that are completely before 0 sec will be deleted, annotations that start before but end after 0 sec will be truncated. Please see also the functionact::transcripts_cure_single.

• TextGrids and contained tiers may start and end at different times. These times do not need to match each other. The act package does not support start and end times of TextGrids and tiers and will. The default start of a TextGrid will be 0 seconds or the lowest value in case that annotations start below 0 seconds.

Details

Cut lists
The commands are collected in cut lists.The cut lists will be stored in different ways:

• A cut list for for ALL search results will be stored ins@cuts.cutlist.mac to be used on MacOS ands@cuts.cutlist.win to be used on Windows.

• Individual cut lists for EACH search result will be stored in additional columns in the data frames@results.The cut lists that can be executed in the Terminal (Apple) or the Command Line Interface (Windows).

Input media files
The function will use all files incorpus@transcripts[[ ]]@media.path.Therefore you will need to set the optionsfilterMediaInclude filtering for which input media files you want to create the cuts.The filter is a regular expression, e.g.'\.(wav|aif)' for '.wav' and '.aif' audio files or'\.mp4' for '.mp4' video files.

Output format
The output format is predefined by in the options:

• act.ffmpeg.command defines the basic FFmpeg command

• act.ffmpeg.command.fastVideoPostioning defines the FFmpeg command to be used with large video files.

The default is to generate mp4 video cuts. You can also use the following commands to change the output format:

MP4 video cuts with original video quality:

• options(act.ffmpeg.command = 'ffmpeg -i "INFILEPATH" -ss TIMESTART -t TIMEDURATION OPTIONS -y "OUTFILEPATH.mp4" -hide_banner')

• options(act.ffmpeg.command.fastVideoPostioning = 'ffmpeg -ss TIMESTARTMINUS10SECONDS -i "INFILEPATH" -ss 10.000 -t TIMEDURATION OPTIONS -y "OUTFILEPATH.mp4" -hide_banner')

MP4 video cuts with reduced video quality:

• options(act.ffmpeg.command = 'ffmpeg -i "INFILEPATH" -ss TIMESTART -t TIMEDURATION OPTIONS -vf scale=1920:-1 -b:v 1M -b:a 192k -y "OUTFILEPATH.mp4" -hide_banner')

• options(act.ffmpeg.command.fastVideoPostioning = 'ffmpeg -ss TIMESTARTMINUS10SECONDS -i "INFILEPATH" -ss 10.000 -t TIMEDURATION OPTIONS -vf scale=1920:-1 -b:v 6M -b:a 192k -y "OUTFILEPATH.mp4" -hide_banner')

WAV audio cuts:

• options(act.ffmpeg.command = 'ffmpeg -i "INFILEPATH" -ss TIMESTART -t TIMEDURATION OPTIONS -y "OUTFILEPATH.mp3" -hide_banner')

Advanced options
You can adjust the FFmpeg commands according to your needs.The following options define the FFmpeg command that will be used by the package. The command needs to contain place holders which will be replaced by the actual values in the package. If you want to define your own ffmpeg command, please make sure to use the following placeholders:

• INFILEPATH path to the input media file.

• OUTFILEPATH path where the output media file will be saved

• OPTIONS FFmpeg options that will be applied additionally, in particular fast video positioning.

• TIMESTART time in seconds where to begin the cutting

• TIMESTARTMINUS10SECONDS time in seconds where to begin the cutting, in case that fast video positioning is being used.

• TIMEDURATION duration of cuts.
