OOOOOOOOOOOOOOOOOOOOkkkkkkkkkk... Thank You. I think I've understood everything .
Yes maybe I've understand, but the hardest task is to create .wav files.
CALLSIGNSUS.LST is now ok having added the following callsigns: Sundown VF21, Old Nick VF111, Screaming Eagles VF51, Dakota VF142 and Rock River VF161. Seven sets with 5 callsigns.
MISSIONCONTROL.INI is OK.
SPEECHTEXT.STR: OK I've understood what you mean but I think I must change even Capital letter identifiers because there will be more callsigns and not only 35 leads plus 140 Flights plus 35 Groups... but 40+160+40.
SPEECHSYSTEM.INI is OK, I understand. I have to compare it with files in speech folder to be sure to save the wav files with the correct name...
But I do not know how to make a voice say "Sundown Lead".
Thank You anyway. Your answer is really useful.
