How to use this page

How to run a script

Scripts save Praat users time and effort by automating a sequence of operations. To run a Praat script, go to the Control menu in the Praat objects window and select New Praat script. Then pull up the code for the desired script by clicking on one of the links below. Copy all the code there (e.g. highlight and Ctrl-C on a PC) and paste it into the new untitled script window. Finally, select Run > Run (or type Ctrl-R) in the untitled script window to execute the script.

How to save a script or add it to the menu

In the open untitled script window with the new script pasted in the text box, go to the File menu to Save the script to a convenient location. The Add to fixed menu... command under File can be used to add the current script to one of the head menus in the Praat objects window. Menus can be edited (e.g. to remove previously added scripts) by going to Control > Preferences > Buttons and clicking on the desired command.

How to script in Praat

See the Scripting tutorial under Help in Praat objects or try Setsuko Shirai's tutorial.

  Reports and logs midpoint F1-F2 of vowels delimited by labeled markers in a set of text grids (ML's description).
• log-pitch-maxima (Mietta Lennes)

• extract-voiced-portions (John Tøndering)
  Extract and concatenate voiced portions of selected Sound to create new voiced-portions-only Sound (JT's description).
• save-selection-to-sound-and-textgrid (Mietta Lennes)
  From an open LongSound TextGrid, save selected portion of LongSound and its TextGrid (ML's description).
• from-segmentation-data-files-to-text-grids (Mietta Lennes)

Drawing pictures

• draw-sample-figure (Hugo Quené)
  Demonstrates how to draw a figure (graph) using a script (HQ's scripts).

• shannon-am-noise (Chris Darwin)
  Produce Shannon-type AM noise from a selected Sound file using four bands.

• sine-wave-speech (Chris Darwin)
  Create three-formant sine-wave speech using selected Sound object.
• metronome (Hugo Quené)
  Simple one-beat metronome; see HQ's scripts page for several more complex metronomes.
