• docs/: contains project documentation.
  • The file procedure.md documents data acquisition and processing in detail.
• code/: contains code for data (pre-)processing, organised in the following sub-directories.
  • config/: configuration script for setting up the EMU-SDMS database and the OFS repository.
  • praat/: Praat scripts for data-preprocessing.
  • r/: R scripts for data transformation, wrangling, and plotting.
• img/: figures generated by code/prepare_plots.Rmd.
• renv/: R package library managed by the renv R package.

The data of this project is version-controlled with dvc. A separate dvc repository—which is independent from this git repository—holds the data, and the data.dvc file, which is instead versioned by git, enables data transfer to and from the dvc repository. Due to server limitations at the hosting institution, we cannot grant access to the dvc repository, and we instead make the data available as a .zip archive on the Open Science Framework (https://osf.io/u43sg/).

The archive contains the directories of this GitHub repository and the data directory with the project data. The data directory contains the following sub-directories:

• metadata/: metadata files.
• stimuli/: contains the list of words (word-list.txt) and randomised versions of this list (rand-1:6.txt).
• recordings/: raw and derived recordings, used for forced-alignment and acoustic analysis.
  • raw/: raw (original) .wav recordings with accompanying .TextGrids used for chunking the recordings into separate parts.
  • derived/
    • align/: files generated by the forced-alignment procedure.
    • post-align/: post-alignment files, imported into the EMU database alb-ipa_emuDB/. To avoid data duplication, this folder is not version-controlled, so it doesn’t ship with this repository.
    • illustr/: illustrative recordings of consonants/, vowels/, intonation/, and The North Wind and the Sun.
    • examples/: recordings for the figures with annotated waveform and spectrogram exemplifying VOT and frication.
• alb-ipa_emuDB/: EMU-SDMS database.
• ultrasound/: tongue contour spline data from ultrasound tongue imaging (UTI data on the OSF).
• varia/: a miscellanea folder with files used with different services.

Data collection and processing are documented in docs/procedure.md.
