Class Summary

Class	Description
AdaptationUtils	Generic utilities for voice conversion
BaselineAdaptationItem	This class keeps information on each specific training item For example, a training item for a sentence based voice conversion training database could be a wav file, the corresponding text transcription, label file, pitch contour file, etc.
BaselineAdaptationSet	Baseline class for speaker specific voice conversion training set
BaselineFeatureCollection	Baseline class for indexed binary files of acoustic feature sets
BaselineFeatureExtractor	Baseline class for acoustic feature analysis for voice conversion
BaselineMappingFileHeader	Baseline class for voice conversion function binary file header
BaselineParams	Baseline voice conversion parameters.
BaselinePostprocessor	Baseline class for post-processing operations after voice conversion
BaselinePreprocessor	Baseline class for pre-processing operations after voice conversion
BaselineTrainer	Baseline class for voice conversion training
BaselineTrainerParams
BaselineTransformer	Baseline class for voice conversion transformation
BaselineTransformerParams	Baseline class for voice conversion transformation parameters All specific implementations of transformation stage of a given voice conversion algorithm should use a parameter set that is derived from this class
Context	A wrapper class for representing phonetic context
FdpsolaAdapter	A class that supports voice conversion through weighted codebook mapping or joint-GMMs and FDPSOLA based prosody and vocal tract modifications Reference: Moulines, E.
FileCopier	Generic utility class for renaming and copying voice conversion training files
FileMap	A class for handling source-target frame indices mapping for a single pair
IndexMap	A class for handling source-target frame indices mapping It can be used in various ways:
LsfMatch
MfccAdapter	This class transforms MFCCs to MFCCs
OutlierStatus	Flags for outliers in source and target training data
TargetLsfCopyMapper
VocalTractMatch
VocalTractTransformationData	Baseline class for voice conversion transformation data
VocalTractTransformationFunction	Baseline class for vocal tract transformation functions for voice conversion

Package marytts.signalproc.adaptation Description

Packages for speaking style and speaker identity adaptation in Mary TTS supporting various voice conversion algorithms. The subpackages include:

• .codebook: WEeighted codebook and weighted frame mapping
• .gmm: Gaussian mixture model based spectral conversion
• .gmm.jointgmm: Joint source-target GMM based voice conversion (this method has been used in our group's various publications in 2008 and 2009)

IMPORTANT NOTE: For expressive speech transformation, GMM based technology works better as compared to codebook and frame mapping based methods. For speaker identity conversion, opposite results are observed in various papers.
