I agree with Girlsmum.

Ignore her totally and completely, don't even look at her when she barks. She is seeking attention and any reaction on your part is rewarding her for barking at you and giving her just what she wanted. Turn away from her, sit in a corner with your back to her. Certainly do not shout at her as she will interpret this as you joining in the fun and it will probably encourage her to bark more. Wear headphones, ear muffs, ear plugs, if necessary. When you start this program be prepared for her to redouble her efforts at getting a reaction from you. This is an extinction burst but, after a while, she will realise that she is barking in vain.

Sounds as though she would benefit greatly from some general obedience training.
