Pitch: To PointProcess

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

## Purpose

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).

## Algorithm

  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.
