Voice Dialing with Android

[boe]

Hello,

I have some questions about voice dialing with Android. I'm considering getting it but voice dialing is an extremely important feature to me.

1a - Can I voice dial by BT?
1b - Can I initiate the call by pressing the button on my BT headset?
1c - Does it give me an option to verify?
(on my current phone I say "call Mrs. Smith at home" on my BT headset. Then it verifies it got the name correct and I say "yes" and it dials.

2 - can I assign voice dialing to a physical button on the phone?

3 - Can I disable other voice functions such as checking battery strength or play music?
