I can draw a combination of a Sound and a TextGrid, and the combination of a Pitch and a TextGrid, but I cannot draw the combination of all three, like it appears in the editor window.

Is this a weakness in Praat, or am I missing something?

I haven't been able to do that either, and I think the most convenient way to do so is to take a screenshot.

There is no "out-of-the-box" way of drawing the combination of a Sound, Pitch, and TextGrid object, to form something similar to what you see in the TextGrid editor. However, this does not mean that it cannot be done. You can script this command, making use of one of Praat's strengths.

Whatever you do, please, do not put screenshots on your papers.

Save the following script somewhere you can find it and then execute it with a Sound and TextGrid object selected. You can also select a Pitch object to draw, but if you don't select one, one will be generated with the values you've provided.

The options for the command work in exactly the same way as the equivalent options for the corresponding commands (the Sound options are the same as for the Sound's Draw... command, etc).

The resulting graph should have the same style as that of the rest of Praat's commands.

  • Can you explain why you say "Whatever you do, please, do not put screenshots on your papers"? I'm asking as an end-user, not a programmer: what is the concern, and what is the alternative? – user6726 Feb 28 '16 at 18:55

    @user6726 What goes into making a good scientific plot and what goes into making a good user interface are completely different things. A screenshot carries a lot of information that is not useful, and ends up just being distracting. Besides, with extremely rare exceptions, screenshots are made as raster graphics, which often end up looking terrible when printed. The alternative is a nice, carefully designed, scalable vector graphic, which is more aesthetically pleasing and better at communicating what you mean. – jja Feb 28 '16 at 21:51
  • @jja it was really helpful thanks. – Adel Rahimi Mar 1 '16 at 16:19
