sorry jitterjames to not reply to you hear i didnt chck it cos i found the solution
the problem was in going to options + system + TTS settings and changing voice selection ..... its automatically put it self on ( anna ) the win 7 voice and when i change it to my Acapela TTS voice then i close VC and open it again its will not set the TTS voice for may Acapela TTS its will set it to the win 7 voice ( anna ) again ....... and some times VC crash ........ and to make it work again i need to check the win 7 voice and set it to ( anna) again and then open VC and its will work .....
its like saying who is the master for TTS voice in my computer is it VC or the win 7
so to solve this problem all what i have to do is to set my TTS voice only from the TTs voice ( options + tts voice ) and leav the system + TTS settings set up on win 7 ( anna )
and VC working great now
but i am heaving a new problem now with it ....
i can not switch between my engines some times its work and some times not
for example when i call my engine simon he will answer me and reply for well but when i call my Arabic engine he will also reply but without any voice .. by the way .... voice work great with Arabic even when VC its not in Arabic language and this what make me want to buy it when i finch from testing it and advice all my friends to buy it to .
WHAT I THINK THE PROBLEM IS I THINK ITS IN THE LONG NAME FOR MY ARABIC TTS VOICE IN VC OPTIONS TTS
cos it gos by this name .... ( mehdi, HQ 22k, Arabic, SAPI5, Acapela Multimedia 8 ) maybe VC can not read along name for an engine
