Praat is a curious application that will let you record sounds or import them if you have already recorded them, and analyse them exhaustively. Spectral, tone, intensity and formant analysis are the four fundamental tests you can perform. Once finished, of course, you'll be able to manipulate audio tracks and modify them as you like. Vocal Toolkit is a free plugin for Praat with automated scripts for voice processing.

Commands are grouped into two added dropdown menus, Copy and Process, that will appear when one or more Sounds are selected in the list of objects.


  • Copy: These commands work with two selected Sounds. They are used to modify characteristics of the second selected Sound to match those of the first selected Sound.

  • Process: These commands are used to process the selected Sounds or to create new ones.

The scripts do not modify the selected Sounds but create new Sounds with the processing result.

NOTE: I'm not an expert in phonetics. These scripts were developed as tools for my work as a multimedia programmer and I publish them with the hope that they can be useful.

This plugin is open source and can be used for any purpose.

About Praat

Praat 6.1.42 is a piece of software that helps phoneticians analyze, synthesize, and manipulate speech. Praat enables you to create a source signal from scratch or from an existing speech signal, but also to create a filter or to extract it from an existing source. You can manipulate (change, adapt) both the source and the filter before doing the actual synthesis, which combines the two. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system/platform without restrictions. Praat is available to all software users as a free download for Windows.

Is Praat safe to download?

We tested the file praat6142_win32.zip with 23 antivirus programs and it turned out 100% clean. It's good practice to test any downloads from the Internet with trustworthy antivirus software.

Does Praat work on my version of Windows?

Older versions of Windows often have trouble running modern software and thus Praat may run into errors if you're running something like Windows XP. Conversely, much older software that hasn't been updated in years may run into errors while running on newer operating systems like Windows 10. You can always try running older programs in compatibility mode.

Officially supported operating systems include Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP.
