PitchTier: Get standard deviation (points)...

A query to the selected PitchTier object.

Return value

the standard deviation in the points within a specified time window.


From time (s)
To time (s)
the selected time domain. Values outside this domain are ignored. If To time is not greater than From time, the entire time domain of the tier is considered.

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.
