I wrote a couple of Perl scripts that do just this, converting to and from JSON/YAML, and a Praat plugin to do this from the Praat GUI. Get accurate f0 tracks using a method that combines automatic vocal pulse marking by Praat, manual correction by yourself, a trimming algorithm that removes. You can then expand that Table to include data from the Pitch and Intensity objects (or whatever objects you need).Īlternatively, most (=not all) text-based formats used by Praat are almost YAML, so you could try to convert them and read them as-is into whatever program you want to use later on. command available for Formant objects, which will create a Table with the formant data. To get started, you could use the Down to Table. You could process them within Praat and put the data you want into a Table object with whatever format and structure you want and save it as either a tab or a comma separated file (see my related answer). Praat-specific (you can check them out by using the Save as text file. The first column is the f0 estimate (0 if the frame is judged to be unvoiced) the second column is 1 for voiced frames and 0 for voiceless ones the third column is the RMS ('root mean square') amplitude of the signal in that frame and the fourth column is the serial cross-correlation value of the signal with itself at the lag corresponding to the f0 estimate. In this example, this is not the case, so you need not subtract the mean, but it does not hurt either. This might be the hardest part, since Praat does not have any standard way to export data, and the data formats that it uses, although they are all text-based, are all very. You'll still need to know some things about the audio you're processing, though, like the likely frequency of the maximum formant you are interested in, or the range within which you estimate the fundamental to be (you might want to look at this plugin with automatic methods for estimating f0 range).Īs for the exporting, what I assume you mean by this is that you want this information to be accessible from a program that is not Praat. This code only returns the mean for the sound file and I am wondering if there is a way to avoid getting small chunks of the file and getting the average pitch and instead being able to get the data given the way praat does it like so : Times F0Hz 0.254558 125.982312 0.264558 127.975510 0.274558 123.010164 0.284558 120.761760 0. Intensity = To Intensity: min_f0, 0, "yes" Assuming that by "all possible data about audio" you only mean fundamental frequency, formant structure and intensity contour (and not, say, spectra, pulses, etc), the easiest way to do this is to generate respectively a Pitch, Formant, and Intensity objects.
