A command that creates a Pitch object from every selected Sound object.
to perform a pitch analysis based on a cross-correlation method.
The algorithm performs an acoustic periodicity detection on the basis of a forward cross-correlation analysis.
Note that if you set the time step to zero, the analysis windows for consecutive measurements will overlap appreciably: Praat will always compute 4 pitch values within one window length, i.e., the degree of oversampling is 4.
The other settings are the same as for Sound: To Pitch (raw ac)....
The preferred method for speech (intonation, vocal fold vibration) is Sound: To Pitch (filtered ac).... The command described here is mainly for experimenting, or for applications where you need short time windows; for this latter reason, it is also the standard method for voice analysis.
