This is to say that my recent efforts would be put on the synthesis part of my thesis. The major programs used would be VTCalcs and Klatt Synthesizer. Mbrola is also under consideration. This part is crucial for my investigation in China.
(Beddor, Bell-Berti, Benguerel, Clumeck,Ohala, Vaissière, to cite a few), Ph. D. dissertations about nasality (Amelot, Cohn,Delvaux, Krakow, and Rossato)
EMG large anticipation 2 (activity of levator palatini), fibroscopy 1
*Nasograph, good tool for mesuring VP opening
EMA less anticipation than fiberscope (ICP Grenoble)
Overestimation can be due to CVC where V has a intrinsically lower velum (bell-berti 1991).
aerodynamic, carryover 2
Articulation, articulatory system has compensatory capacities. No precise place of articulation from the production point of view for the vowels, see X-ray data (the lips, the jaw, the tongue and, the larynx) [3, 4]. Also see the block and bite experiment.
Perception, listeners from different native languages show different phoneme identification and goodness ratings when exposed to the same stimulus stimuli 
##ATP for what?
Cardinal vowels, put forward by DJ  8 primary i e E a A u o O and 10 secondary the first 8 secondary = rounded/unrounded He also suggests French vowels and the closest.
five primary CVs were derived as ‘auditorily equidistant’ between three ‘corner’ vowels’ i u A
Problem: Labels are primarily acoustic or perceptual , and not articulatory.
##Discrepancies in real life?
