inpro.synthesis.hts
Class VocodingAudioStream

java.lang.Object
  marytts.util.data.BaseDoubleDataSource
      inpro.synthesis.hts.VocodingAudioStream

All Implemented Interfaces:

java.lang.Runnable, marytts.util.data.DoubleDataSource

public class VocodingAudioStream
extends marytts.util.data.BaseDoubleDataSource
implements java.lang.Runnable

a vocoding thread that that can return immediately and from which the synthesized audio can be read while synthesis is still in progress; this class heavily relies on and borrows from HTSVocoder
