GMM morphed.

Hi all, can anyone help me with this?

If i were to carry out a Gaussian Mixture Modelling on an LPC data,
after that using the resultant i undergo some level of morphing. would
i still need to do any reverse GMM on the morphed data in order to get
back an LPC format? If yes, can someone roughly show me how it can be
done?

p/s the GMM approach i used was the EM algorithm
