Okay, now it’s time to edit something.You now see a dialog window called "Run script: Give the parameters for pause analysis." You’ll see a boring-looking text file, like this: Now open the script: click on Praat>Open Praat script.The newest sound object opened should be selected by default. To do this, from Praat, go to Open>Open long sound fIle. Open Praat, and load the audio file into it as a LongSound object.Download the script file to the same folder.The properties will give you the location of the file, as well as its size and other details. Once the file is on your computer, you can view its properties by right-clicking on it (Mac users, hit Control+click). First, go to your Desktop and make a folder there named pauses.mp3 files, because the time stamps in mp3 files are not accurate. You can hear the original mp3 at the linked page here is the. The script we’ll use is Mietta Lennes’s mark pauses, and the audio file is Newgatenovelist’s reading of Her Hair, a poem from the free Librivox project. Let’s try a simple script, which is known to run on a pre-chosen audio file. This requires an analytic approach that can be a lot of fun, as long as you frame the problem correctly. You need to decompose the situation that leads to failure into steps that you can change, one at a time, to isolate the step that is causing problems. See, Praat cannot read your mind, but you have to read its mind. You are eventually going to encounter some situations where things go wrong, but Praat doesn’t tell you why. You need to be extremely attentive to detail. (I’ll explain what “whitespace” means below.) Approximate is not good enough you have to be precise. If you’re working with existing scripts, as in this tutorial, you generally don’t have to worry about that.)Īnother side effect of Praat’s not knowing how to read your mind is that you have to be very careful with typos and whitespace. (You need to tell the computer the order in which to do things, too. You need to tell the computer exactly where stuff is. The challenge before you, then, is to learn how to talk to a 90’s computer. It is meant for people who know their way around their computer and who understand how to get the computer to do things the old-fashioned way. It has been continually maintained, and features have been added to it, but its basic nature is very 90’s. One side effect of this is that kids these days can’t find things on their computers.īy contrast, Praat was originally written in the late 1990s. They keep your stuff organized for you, so that you can search for pictures or music or videos and somehow always find it. Websites and web apps are designed to try to read the user’s mind, and to fail gracefully in the face of typos and missing pages. Thus, your familiarity with computers is intimately tied with how the internet has evolved. Most of the apps on your phone are fronts for web apps–they allow you to interact with a website or a distributed network. If you are like most students taking an introductory phonetics course right now (I’m writing in 2021), the internet has always existed for you, and it isn’t your mom’s internet of 2002. 4 Some other gotchas in Praat scripting.3 A random list of problems and solutions. ![]() The confidence builder exercise below talks you through that. The most basic thing you will do with a Praat script is make it run and tell it to do something to a file you provide, and then save the result to your computer. But Praat can rapidly collect the durations of labeled intervals from a TextGrid for you, if you prepare the right sort of TextGrid and tell Praat exactly what you want. Praat cannot accurately label the edges of those consonants for you–that task falls under “smart stuff” that requires human eyes and ears. For example, suppose you are working on a study where your interest is in measuring durations of certain consonants. The point of Praat scripting is to automate tasks, so you, the human, can do all the smart stuff, and leave the computer to do repetitive boring stuff. It is intended for students in an introductory phonetics course, who usually have little to no background in working with scripts or programming languages. All it covers is how to use scripts that someone else wrote. This guide is not going to teach you how to write your own scripts, or even how to modify existing scripts in minor ways for your own needs. Goal: Before you attempt to write your own Praat script, you will probably try to use one of the many existing scripts.
