If you’ve ever had to fiddle around with getting a Praat Picture to look and export just right in order to insert it in an R markdown file or slide deck, then this package is for you! Even if this isn’t the case, the package offers some very useful flexibility. It’s a simple set of functions designed to emulate some common plots made in Praat Picture with base R plotting. It allows for flexibly combining waveforms, spectrograms, TextGrids, pitch tracks, formant tracks, and intensity tracks in a single plot. The derived acoustic plots can all be generated directly in R, or (except in the case of spectrograms) generated in Praat.
TextGrids can be plotted as long as there is a file with the .TextGrid extension in the same directory and with the same base name as the sound file. If there are files with the .PitchTier, .Formant, and .IntensityTier extensions generated in Praat, these are loaded in using the rPraat package and used for plotting. Otherwise, signal processing functions from the wrassp package are used in a way that emulates Praat default settings as closely as possible. Spectrograms are generated with the phonTools package.
If you are an emuR user, the emupicture function will help make Praat Picture style plots of sound files, annotations, and possibly SSFF files from an EMU-database.
For more information on how to use the package, see the manual.
