summary of responses - CV Formant transition values, ba-da-ga in french or english,


My question has rfeceived relevant answers, I am greateful and I wanted to share some references that were advised to me off-list :

Kewley-Port, D. (1982). Measurement of formant transitions in naturally produced stop consonant–vowel syllables. JASA, 72, 379-389.

Lisker, L. & Abramson, A.S. A cross-language study of voicing in initial stops: acoustical measurements. Word, 1964, 20,384-422.

Dominic W. Massaro and Michael M. Cohen - Evaluation and Integration of Visual and Auditory Information in Speech Perception, Journal of Experimental Psychology: Human Perception and Performance 1983, Vol. 9, No. 5, 753-771

Also somebody mentionned that there are many pitfalls to avoid when using synthesized speech and pointed me to http://hear.ai.uiuc.edu/wiki/Main/Publications for further references.

I am setting up a pilot experiment on syllable speech perception using the ba, da and ga syllables.
This seems to be a recurring question, I have searched the auditory archive prior to asking and coulnd't find any answer.
Many articles have generated similar stimuli, but the information they provide in the method section is never sufficient to synthesize similar sounds, (for example only initial formant values are specified). I have been trying it out using Klatt synth or Praat but I was unsuccesful.
The online Klatt synth from Timothy Bunnel (U. Delaware) provides an example of a ba generating script, with the values of various formants and params varying in time. I am looking for similar values for the da and ga syllable. 
Ideally I would appreciate hints on how to make a ba - da - ga continuum, and optimize distinguishibility, in french or english. I would like to make exagerated versions of those syllables in order for them to be very saliently distinguishable.

Thanks a lot in advance for your advices,
