Thank you Gil for your help.

However, I still have 2 questions: (sorry about i don't know to much programming):

1) Is just this code which i have to insert it? What does this numbers "1,1,3" mean?

SCRIPT LANGUAGE="JavaScript"

function vh_sceneLoaded(){ //event function
singAsong();
}

function singAsong(){
sayText('my_paragraph1',1,1,3);
sayText('my_paragraph2',1,1,3);
sayText('my_paragraph3',1,1,3);

}
/SCRIPT

2) Where exactly have i put into this code?

Many thanks.

:)
Could you tell me where i should put the code sayText exactly?
