FormantGrid

One of the types of objects in Praat.

A FormantGrid object represents spectral structure as a function of time: a formant contour. Unlike the evenly sampled Formant object, it consists of a number of formant tiers and bandwidth tiers, each of which contains a number of formant or bandwidth points (or targets), sorted by time.

For examples, see Source-filter synthesis.

## FormantGrid commands

Creation:

  From scratch:
  • Create FormantGrid...
  • FormantGrid: Add formant point...
  • FormantGrid: Add bandwidth point...
  Copy from another object:
  • Formant: Down to FormantGrid: trivial copying of frames to points.

Synthesis:

  • Sound & FormantGrid: Filter: see Source-filter synthesis.

Modification:

  • FormantGrid: Add formant point...
  • FormantGrid: Add bandwidth point...
  • FormantGrid: Remove formant points between...
  • FormantGrid: Remove bandwidth points between...
