How to synthesis a speech which I need?

[sanena]

Hello!It’s not long for me since I just learned voice conversion.So I have many questions, and one of which is how to appoint the source speech and the target speech so I can synthesis the speech which I need.
In short, Could you tell me how to restructure the demo.pkl?
If you can answer me ,I'll be very grateful!

Actually,I believe the structure of demo.pkl is:

-sbmt[0](the data of speaker1)
--name of the speaker,e.g. P226
--one-hot vector of the speaker
--four components
---x0(the mel spectrum of the wav)
---f0(symbolize as pitch)
---length of x0 or f0
---a number I don't know the meaning

-sbmt[1](the same as above)
....
You can print them out to see the details.
