No mapping used here. We select the frame directly from the MFCC's of the source (Thierry). A DTW is runned to align the frames selected on the target. And the excitation of the target is used for LPC synthesis with the AR corresponding with the selected frames. 

Summary:

- No mapping (use directly X MFCC)
- DTW to align X on Y
- Selection by projection
- LPC synthesis using target excitation.
