I hope someone else finds it helpful! You can copy the code and paste it into a text document that you might call something like vary_duration_and_pitch.praat. The file names include tags indicating how duration and pitch were modified. wav files in a directory (the directory where the script is located), randomly compresses/expands the file according to a hard-coded range (i.e., you have to change the values in the file), randomly adjusts pitch (by multiplying by a scalar), and writes the resulting file in a folder called output that must exist in the starting directory. Putting them together, I now have a script that is called from the command line and reads in all. I found a script by Shigeto Kawahara of Keio U. We thought, “let’s just use a Praat script to randomly jigger duration and F0 - that can’t be hard, can it?” Well, it is harder than I thought given that I don’t really grok Praat scripting - it is the most foreign and strange programming language I’ve ever encountered.Īfter consulting with various colleagues, I remembered that Sergey Kornilov had used a script to compress lots of files for a project. wav files in a directory and modify them from the command line.įor a machine learning project, we wanted to induce variability in a set of speech files without recording more tokens of our critical words.

It can serve as an example for how to read in all. Summary: I describe a script that makes random modifications to duration and pitch. Randomize duration and F0 of speech files in Praat
