I am performing some large-corpus analyses in Praat and have been extracting formant (F1, F2, F3) values at every 10 interval for my textgrids, but have decided that a much more even-handed measure would be to extract these parameters once every half-second or so in each of my intervals, but I. The first argument is a timeout in seconds (=die if action is not completed by then), then the name of the program, and then a list of commands to run sequentially.Īs far as I know, there is no straightforward way to run a single script that will, in one step, open a GUI version of Praat and make that instance of Praat execute a command.

This library also provides some other tools for use with praat. This library isnt just a data struct for reading and writing textgrids-many utilities are provided to make it easy to work with with transcripts and associated audio files.
