Rachael Farlane provides the voice for Hayley Smith in the show "American Dad." I think that she does a great job providing her voice, but not the best. I still think that she is talented, though. Even though anyone could voice Hayley, IMO, I still say that I like her voicing Hayley. She has a good voice, but nothing special. She is underrated, too. Overall, great, but not the best.
