Pitch: To PointProcess

A command that uses a Pitch object to generate a PointProcess.


to interpret an acoustic periodicity contour as the frequency of an underlying point process (such as the sequence of glottal closures in vocal-fold vibration).


1. A PitchTier is created with Pitch: To PitchTier.
2. The algorithm of PitchTier: To PointProcess generates points along the entire time domain of the PitchTier.
3. The PitchTier is removed (it never appeared in the List of Objects).
4. The voiced/unvoiced information in the Pitch is used to remove all points that lie within voiceless frames.
