public static class MaryGenericFeatureProcessors.UnitLogF0
extends Object
implements ContinuousFeatureProcessor

Calculates the log of the fundamental frequency in the middle of a unit segment. This processor should be used by target items only -- for unit features during voice building, the actual measured values should be used.

Method Detail

getName

public String getName()

Specified by:

getName in interface MaryFeatureProcessor

public float process(Target target)

Specified by:

process in interface ContinuousFeatureProcessor

process

protected float process(Target target,
                        boolean delta)

Compute log f0 and log f0 delta for the given target.

Parameters:

target - target

delta - if true, return the delta, i.e. the logF0 slope; if false, return the log f0 value itself.

Returns:

0 if seg is null, or if !seg.getTagName().equals(MaryXML.PHONE), 0 if lastPos == null or nextPos == null, return lastF0 otherwise; if delta return slope, return f0 otherwise
