This R package contains the acoustic and electroglottography measurements from the UCLA Voice Quality Project. It also provides plain text versions of the word lists for all of the languages in the project.
The original data have been converted into the tidy data
format for use with the tidyverse family
of R packages. The scripts that were used to convert and clean the original
Excel and PDF files are in the data-raw directory (tidy-*.Rmd).
If you want to use the data or word lists without using R, all of the tables in
this package are also available in CSV format in the data-raw/csv directory. A
description of each table is in the R/data.R text file.

To install the package from GitHub, run this command in R:
devtools::install_github("scjs/ucla-voice-quality")
You may need to install devtools first:
install.packages("devtools")
To see a list of the tables included with the package, use the data()
function:
data(package = "voicequality")
To read a description of a table, use the help() function:
help("acoustics", package = "voicequality")
help("egg", package = "voicequality")
To load a table, use the data() function with the table name. For example,
this will load the table named acoustics, which contains the measurements from
the master acoustics spreadsheet on the project site:
data("acoustics", package = "voicequality")
For a usage example, see the gujarati
vignette.
