Listing 3—This task is called from the main routine to synthesize more phonemes or translate the remaining text.

void Task_Speak(void){
  	static int gen_resume = 0;
  	int trans=0;	
	gen_resume = MCU_Generate(MCU_phoneme_list,&MCU_n_phoneme_list,gen_resume);
  	if(0 == gen_resume){	//if there is nothing in the phoneme list 
		if(p_cgen != NULL){	//is there more text?
    		trans = MCUTranslate(NULL);	//if so, translate the rest
     	MCUCalcPitches(1);	//analyse prosody
      	MCUCalcLengths();
     	gen_resume = MCU_Generate(MCU_phoneme_list,&MCU_n_phoneme_list,0);
      	if( (trans ==0) && (0 == gen_resume) )
       			p_cgen = NULL;	//finished to synthesize
		}
  	}
