Does Word have a voice recording capability?

I was in lecture the other day and the guy next to me was taking notes on his laptop. The program he was using looked like Word, but I could be wrong. I also noticed that there was a bar at the top with colored bars flashing back and forth. I asked him what it was and he said he was recording the lecture. SAY WHAT!? He left half way through the lecture and I didn’t get a chance to ask him what it was or how to use it.
So my question is: Does Microsoft Word have a voice recording element to it that I can use while I’m taking notes? Is it another program that I have to download and use in addition to Word?
In case you need to know, I’m using a MacBook Pro and currently working with Microsoft Office 2008.
