voice morphing

I am a graduate student.

Recently, I am focusing on voice morphing, a technique to convert the voice personality, making one's voice sound like a desired target's voice.

I have done some research on mapping the parameters of spectrum, then synthizing the target speech with the modified spectrum.

However, until now, I haven't found a good way to deal with the excitation signal, which also plays a vital rule in the morphing process.

Do you have something to recommend to handle the excitation signal?

Additionally, I wonder whether there is a way to add the personal characteristics into the speech signal.

Thank you.

Best,
