Select "Sound be" and "TextGrid be" and click View & Edit, and note that the second tier has split this syllable into segments. An example using object selection: Extracting part of a sound I'll explain why I think so after we do this next example. For one, those numbers are going to be different every time you use Praat, so we absolutely cannot hard-code them (object 7 will most likely be different the next time you run the script), but in truth there are some great advantages to using the numbers, and I generally prefer them. At first glance, the numbers version may seem to be the lamer option. Which version you should use depends on your situation. Change which version of the command is commented and uncommented, and run it again. Now to make sure both commands work, click on a different object like "Sound ba", comment out the command you don't want to test (put a hashtag in front of one of the selectObject commands), and run the code. In a blank scripting window, type in the two following ways we can select the object "Sound a", adjusting the numbers to work with what you currently have open. The numbering starts at 1 when you open Praat, and will keep going up as you create more objects or open more files. Look to the left of each object, and note that they have been assigned a unique number. There are basically two ways we can select files in Praat: by using the object's name or by using its number in the object window. Hopefully you now see plainly why we need to learn how to select objects in Praat via script: we won't get very far without it. This should generate an error saying that the given command is not available, which is true, because that command is only available when a text grid is selected, and right now a sound is selected (other times this error simply means you've spelled the command wrong). Open a Praat scripting window, type this in, and run it: What we want to note here is that we have different commands available to us when different object types are selected. Now select a sound and its corresponding TextGrid together (ctrl), and look at the available commands. Now click on a text grid and look at the commands. Though we already went through this, click on a sound file and look at the available commands on the right. TextGrid files in sampleData/ (if you haven't downloaded the accompanying files, go to the Downloads page from the top right menu). For each label in that tier, it extracts the word, start and end of the stressed vowel associated with the pitch accent, and acoustic landmarks from labeled points L (optional) and H (not optional).Open all of the. Hscript is a modification of the f0 points multi script, which cycles through the file based on labels in a "nuclear" tier, which tags each pitch accent as nuclear or non-nuclear. This script only gives one line per file, with the appropriate f0 landmarks, full orthographic transcription, and ToBI annotation of the utterance.īoth scripts give the f0 Max and Min for the utterance, based on landmarks in a separate tier, and have the option of either running through the files blind, or checking each f0 point by hand. The second script is for when you have multiple files with different types of f0 landmarks marked in each: one file might have the start and end point of a rise the other might only have the f0 at the midpoint of a plateau. The script creates a new line for each peak, which includes the word and pitch accent closest to that peak, along with the full orthographic transcription and ToBI annotation of the utterance. The first script is for when you have multiple instances of the same f0 landmark (say, a peak) in a file. TextGrids in a folder.įinally, "f0 points multi" and "f0 points single" scripts function in similar ways, but are for two different sets of data. "basic tobi extract" will extract a ToBI annotation and a word level transcription from a series of. wav files in a folder, (2) add a tier to already existing TextGrids, or (3) update and save annotations in existing TextGrids. "add-phon-tier" allows you to either (1) create TextGrids for a series of. The files will be automatically named based on the label in that interval tier. wav), based on segmentation given in an interval tier. "Segmenter" will chop a longer file (.TextGrid and. They are all shared under a GNU General Public License. Most of them are used for working with files that are to be, or have been, ToBI annotated. The following Praat scripts were all based on pre-existing scripts given to me by others (see full credit, where possible, in the files).
