PitchTier: To PointProcess

A command that uses a PitchTier 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

Points are generated along the entire time domain of the PitchTier, because there is no voiced/unvoiced information. The area between two adjacent points under the linearly interpolated pitch contour, is always 1.
