what does the voice feature do in modems?

in a data fax voice modem, what is the voice feature?

I believe what you are referring to is the ability to talk to other people over the modem as if you had a microphone hooked up to your computer and dialed them using the modem, and you would hear them through your speakers. I've never used the feature, so I could be way off base.
