![]() ![]() In a nutshell, you can write up to two scripts and link them to Alt + F12 or Ctrl + F12, and pressing those keys in the editors will execute the specified scripts (in editor mode!). As far as I know, the only platform-independent way in which you can specify what some keyboard shortcuts do is by using the logging scripts, and these only really work in the Sound and TextGrid editors. Multiply by 0.Praat has very bad support for shortcuts. InĬontrast with what is described in the article, this value will be corrected for the time step: To decrease the number of voiced/unvoiced transitions, increase this value. Voiced / unvoiced cost (standard value: 0.14) degree of disfavouring of voiced/unvoiced transitions, relative to the maximum possibleĪutocorrelation. TimeStep to get the value in the way it is used in the formulas in the article. In contrast with what isĭescribed in the article, this value will be corrected for the time step: multiply by 0.01 s / To decrease the number of large frequency jumps, increase this value. Octave-jump cost (standard value: 0.35) degree of disfavouring of pitch changes, relative to the maximum possible autocorrelation. To more strongly favour recruitment of high-frequency candidates, increase this value. Periodic signal, all undertones of F0 are equally strong candidates as F0 itself. This is necessary because even (or: especially) in the case of a perfectly Octave cost (standard value: 0.01 per octave) degree of favouring of high-frequency candidates, relative to the maximum possibleĪutocorrelation. To increase the number of unvoiced decisions, increase this value. Voicing threshold (standard value: 0.45) the strength of the unvoiced candidate, relative to the maximum possible autocorrelation. Silence threshold (standard value: 0.03) frames that do not contain amplitudes above this threshold (relative to the global maximumĪmplitude), are probably silent. The settings thatĭetermine the cheapest path are: Pitch ceiling (Hz) (standard value: 600 Hz) candidates above this frequency will be ignored. twice the effective length.Ī post-processing algorithm seeks the cheapest path through the candidates. If on, the window is a Gaussian window with a physical length of 6 / Very accurate (standard value: off) if off, the window is a Hanning window with a physical length of 3 / ( pitchįloor). The window will be 1/75 = 0.01333333 seconds long. ![]() Of the analysis window: it will be 1 longest period long, i.e., if the pitch floor is 75 Hz, Pitch floor (Hz) (standard value: 75 Hz) candidates below this frequency will not be recruited. In this example, Praat computes 300 pitch values per second. 0.00333333 seconds if the pitch floor is 75 Hz Sound to Pich (Cross-correlate) Time step (s) (standard value: 0.0) the measurement interval (frame duration), in seconds. This parameter determines theĮffective length of the analysis window: it will be 3 longest periods long, i.e., if the pitchįloor is 75 Hz, the window will be effectively 3/75 = 0.04 seconds long. This example, Praat computes 100 pitch values per second. 0.01 seconds if the pitch floor is 75 Hz in Sound to Pitch (Auto-correlate) Time step (s) (standard value: 0.0) the measurement interval (frame duration), in seconds. Of the Time step and Pitch floor parameters differ depending on theĬhoice of Auto-correlation or Cross-correlation. from the Praat menu in the SpeechĪnalysis view of the Session Editor window. The Pitch settings window can be opened by choosing Pitch
