Syllables frequency distribution ?

Hi guys,



I am in a bit of hurry with my project. This is my first mix for psotproduction.



I know where the general speech recognition lies in frequency spectrum but I am wondering... Can somebody point me to frequency distribution for single syllables .

For example , I cannot seem to effectively treat K to be disitinct. Or J (not like in DJ its slavic, so its like heY Ya).



I would appreciate if somebody could point me to some links with or without charts, books or just say it here.

Thanks in advance and have a good day
