I'm Vietnamese, but I live in the United States all my life so I can barely speak Vietnamese. My grandparents are coming to visit and they always speak to me in Viet, and so I usually just nod my head awkwardly.

I figured I might as well learn to speak it better, so are there any websites or dictionary programs that not only translates from Vietnamese to English, but has a sound byte of how to say the Vietnamese word? Thanks.

My brother is adopting a boy from Vietnam, and he is going to name the baby Quinn.

Can you tell me if there is a Vietnamese word that is pronounced the same as "Quinn" (in English), and if so, what does it mean? We've tried to look it up, but we really have no idea how to pronounce anything, so looking up spelling doesn't do much good.

Thank you.
What does it mean? That's the important part of the question.
And yes, Quinn is a boy's name.
