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