Class SegmentModel

java.lang.Object
  extra.inpro.synthesis.visual.SegmentModel

public class SegmentModel
extends java.lang.Object

the data model that can be manipulated by VisualTTS. We support mbrola data (i.e. segments and associated lists of pitch marks) and import from and export to mbrola format.

Field Detail

segments

private final java.util.List<SegmentModel.Segment> segments

activeLabel

private SegmentModel.Segment activeLabel

one of the segments may be active, meaning that it can be modified by moveRightBoundaryOfActiveLabel, moveAllBoundariesRightOfActiveLabel, ...)

activePitchMark

private PitchMark activePitchMark

one of the pitchmarks may be active. it can then be modified by setPitchOfActiveMarkTo().
