For an explanation of them, you can consult online Praat help, which I have reproduced here. For other parameters, select Advanced Pitch Settings. To adjust the min and max (and other parameters), select Pitch Settings. These worked fine for the female speaker that is presented in these notes. The default settings in Praat are 75 - 500 Hz. For a male, a reasonable range is 75 - 300 Hz, for a female, 100 -600 Hz. These can be set depending on the pitch range of the speaker. The most common ones that need adjusting are the minimum and maximum F0 values used for the analysis. If there is such a problem, you will need to adjust the analysis parameters. voiceless according to the algorithm) where the signal is actually voiced, or conversely, voiceless intervals where some pitch value is found. However, sometimes there will be sharp jumps in the pitch contour (which are physically impossible), or places with no pitch values (i.e. (5) If the curve looks the way you expect, then you are done. (4) You should now see a display like Figure 1 below, with the Waveform on top and F0 contour on the bottom. In the resulting dialog box, check Show Pitch, and unchecked everything else. (3) From the View menu of the Edit window, select Show Analyses. You will get the familiar waveform and/or spectrogram display. (2) Select the sound from the list of objects and click on Edit. A corresponding Sound should appear in the list of Praat Objects. (1) Launch Praat and open the file containing the utterance whose F0 contour you wish to measure, by selecting Read from File. Getting the Pitch Contour of a given utterance F0 measurement in Praat seems to work quite well. These algorithms are not fool-proof (it turns out that automatically measuring F0 is not an easy problem), so sometimes you have to adjust parameters of the analysis to get a satisfactory result. There are, therefore, useful mathematical algorithms that calculate how F0 changes over time. However, if we want to know exactly how F0 changes over time in the course of an utterance (the F0 contour), it would be very time-consuming to measure the duration of each pitch period. It is easy to measure fundamental frequency at a given point in time from the duration of the fundamental period.
