Your p/invoke function is potentially overflowing the stack.
It it also passing unparsed strings to the system() call:

int Speech(char* frase)
	char command_final[50];
	strcat(command_final, "echo ");
	strcat(command_final, frase);
	strcat(command_final, " | festival --tts");

So why are you not coding this in C#? (see System.Diagnostics.Process
and System.Diagnostics.ProcessStartInfo.RedirectStandardInput).
