V551- How do I add a voice dial?

I have read through the manual, but can not find how to actually add a voice
command to an address book entry to use for voice dialing. Can someone help
me out with this?

Also, is there any way to set all call "voice-dialed" to default to
speakerphone? Since the reason that I would use voice dial is the same as
using speaker phone (because I am driving), that would be a nice feature.

Thanks!
