jdr33 you're right ......you're right i think i have proved it with simple experiment
do you remember when you told me "
"""The phonetic features are well established. One modern way to show this is to use fMRI to give us a modern equivalent to x-rays. Certainly it isn't exactly the same as 1+1=2 due to articulators interaction and so forth but it's close. I don't see how it would be q because that is a stop. """"" First of all don't tell me it's a silly or worthless experiment as you told before about the Praat experiment

I used "Audacity sound recorder/editor : it is fantastic multi track software from sourceforge.net ""
I recorded the sound of 't' as normally pronounced on one track , on other track I recorded the sound of "؟ ain" but with the tongue on same articulation of 't'
"without releasing 't' of course ""since Audacity has a good feature to move the waveform on its own track as you want ""left or right"" ,patiently i found the point where the two consonants started simultaneously , here was my proof the sound was Ar. [tˤ]
I repeat the same procedure with "q" it doesn't produce the tˤ exactly but some thing i can't recognize .
Here is the results for both experiments , first link "t" with "ain" and the 2nd "t' with "q"
