Thanx for thinking.

Yes, I read about that of course but in my opinion it's not a problem with the TTS engine not working because
it works with : Voice_TTS-Pro-Android-Next-Nuance(ve)-Dutch-Xander-kajoe-v.9.181.zip
But why not with : Voice_TTS-svox-dut-f1-lua.zip
I should say there is a difference in the file ?
