Praat formant extration code11/13/2023 However, in order to make the formant chart reflect the real position of different vowels in oral cavity, it is better to convert the formant values (in Hz) to the auditory Bark scale using the formula of Zwicker and Terhardt (1980) and plotted on a chart of F1 (on the y-axis) against F2 (on the x-axis), to give a representation of the open-close and front-back quality of the vowels. 9 and Figure 2.10).įigure 2.9 Figure Formant frequency chart for HK speaker 2Īfter that, you can convert your data in Excel to make the following formant chart.įigure 2.10 Formant chart for HK speaker 2 Hung (2000: 341) has given us a good example to show the vowels (See Figure 2. In our research, after getting F1 and F2 of the vowels from Praat, what we need to consider is how to present them in an informative way. Go to "Editor"→"Formants" →"Formant Listing", which will give you values for F1, F2, F3 and F4, along with the time point at which the measures were taken.Position the cursor in a stable and middle part of the sound and do the following.If you downloaded praatio from pip, you can get the example files 29 on the praatio github page: 30 () 31 32 There is also a tutorial for working with praatio on the github page.Before we start to plot the vowels, let’s review on how to extract formant values (see details in 1.4.5.) 26 27 For example scripts that use various parts of the praatio library, please see 'examples/' 28 in the root directory. 23 24 **praatio_scripts.py** contains code that combines various code in praatio-mostly 25 high-level functions for working with textgrids, sometimes in conjuction with audio files. 21 22 **audio.py** is for reading, reading, and performing simple manipulations to wave files.
