A query to the selected PitchTier object.
the standard deviation in the points within a specified time window.
For a PitchTier that was created from a Pitch object, this command gives the same result as Get standard deviation.... for the original Pitch object (but remember that variation measures based on quantiles, as available for Pitch objects, are more robust).
To get the standard deviation in the entire curve, i.e. weighted by the durations of the line pieces, Use PitchTier: Get standard deviation (curve)... instead.
