Praat is an open-source phonetics program, and R is an open-source programming language often used by linguists to do statistics. Both of them are excellent and well-established, but it’s fairly tedious to use them together. PraatR is a new free tool for doing just that, and looks really useful for linguists doing numbers-heavy acoustic phonetics, and possibly other things. From PraatR’s website:
An increasing number of researchers are using the R programming language for the visualization and statistical modeling of phonetic data. However, R’s capabilities for analyzing soundfiles and extracting acoustic measurements are still limited compared to free-standing phonetics software such as Praat. As such, it is typical to extract the acoustic measurements in Praat, export the data to a textfile, and then import this file into R for analysis. This process of manually shuttling data from one program to the other slows down and complicates the analysis workflow.
The present software architecture (‘PraatR’) is designed to overcome this inefficiency. Its core R function sends a shell command to the operating system that invokes the command-line form of Praat with an associated Praat script. This script imports a file, applies a Praat command to it, and then either brings the output directly into R or exports the output as a textfile. Since all arguments are passed from R to Praat, the full functionality of the original Praat command is available inside R, making it possible to conduct the entire analysis within a single environment. Moreover, with the combined power of these two programs, many new analyses become possible.
It’s definitely the kind of thing that assumes knowledge of R and Praat already though, so you may also wish to start with this R tutorial for linguists, these R exercises for computational linguistics, or the guide on the Praat site.
