I'd suggest you just try it. Whatever works, works. You'll notice soon enough what makes her calm down, and what doesn't.
I don't think there are rules to this, and not all babies respond to exactly the same things, even though some things generally work better than others. A lot depends on why the baby is crying. If she's hungry, most likely nothing except feeding her will work. If she's upset or scared or hurting, then holding her and talking to her will help to calm her. I think it's unlikely that your voice will irritate her; remember that it's your voice that she's heard for all her life, even when she wasn't born yet, and it's more likely that the absence rather than the presence of that voice is irritating.
With my oldest son, we never knew why he was crying all the time, but I noticed that when I sang to him in a deep voice while carrying him to and fro, that often helped to calm him down. At other times, nothing helped at all.
