From what you described it sounds like she just wants to carry on a conversation with you. I've had 2 dogs like that, my Cairn Terrier, Maddie and my Smooth Collie, Oz.

When I'd get home from work, Maddie would be so excited, she and I would WooWooWoooooo back and forth at each other. She also had all kinds of different vocalizations that meant everything from I need more water to I need to go outside and potty.

Oz is very communicative too. He comes and barks at me whenever there's anything amiss in the house and won't stop until I go check it out. He's so Lassie-like. When he's excited we bark back and forth at each too, like I did with Maddie. Although it's not a cute lil' WooWooWooooo sound, it's woof woof woofing.

As long as they have a happy relaxed body posture and they'll stop barking when you tell them to, I wouldn't worry about it.
