Yea, I know about BTAudio, but have had some issues with it, and other similar 'hacks'. The reality is that the phone and BT headset need to work over the headset/handsfree profile and the music should really work over an A2DP profile. VC is a headset/handsfree implementation. If you use it to start music, the unit should cut off the HS/HF and start up the A2DP. If you then get a call, the functionality should be to pause the music via the A2DP and control portion thereof, and use the HS/HF to process the call, answer, route audio, hangup, and then switch back to the A2DP and start the music again. I have stereo headsets (like Motorola's) that support both HS/HF and A2DP, and they work as expected, if the device supports both protocols. Neither the K-Jam nor the Scala do. Things like BTAudio need to trick the system into thinking it is in a call to route audio from something other than the phone subsystem (like media player) into sending that audio over the mono phone based HS/HF profile so you can hear it on a 'mono' headset'. I've found that often interferes with the normal phone function. While the phone understands a call coming in, the audio system believes it is already in a call, and gets confused. Just my experience. If it works OK for others, great.
Voice tags are significantly different than what VC does. Voice tags compare a digitized audio command to a previously recorded digitized audio command. This is a much simpler problem to solve than what amounts to recognizing speech and comparing it to words. If it is poorly digitized and transferred when you create the tag, it just needs to compare that poorly digitized and transferred file to the earlier poorly digitized and transferred file. It's kind of like having two blurry pictures. You can tell if they are the same, even if you can't tell what they are. There are two levels of difficulty in what VC does. There is the recognition of distinct commands, and there is the recognition of random names, both from the contact list, and from media files. Commands are significantly easier, as you can compare what was said to a finite list. Recognizing names is a real challenge, and is compounded if the digitization and BT transfer is poor.
I haven't had much experience with VC and the newer devices running WM6 and the newer BT stacks, MS or others. I would guess though that the VC team is working on the issues. 1.6 came out some time ago, well before WM6, and I am not surprised that there are issues, based on a few years of dealing with the various distinct and compartmentalized activities within MS.

Hi Sven,
I'm happy you're able to use Voice Command 1.6 bluetooth functionality. It
worked on my old K-Jam as well. The problem is with pretty much all the new
devices out there. It's really upsetting because I know it could work as the
included Voice Dialer which uses Voice Tags does work with a mono bluetooth
headset.
As for your passing audio to your headset for media player ect. I used to
use a handy little program called BTAudio on my old K-Jam. Do a search in
google for BTAudio and you'll find it. You can run it to toggle all audio to
the bluetooth headset when you want to listen to sound through the headset.
As for me and all the other users out there who have newer devices like the
HTC Trinity/TyTn ect. I hope Microsoft is listening and is working on some
kind of solution either themselves or with their partners.

Regardless of the sig block, this isn't a paid endorsement. My copy of VC
1.6 works just fine with VC over BT. I use it with my K-Jam (an HTC device),
and have used it with an SP5 (another HTC gizmo). Primarily my use is with
a Cardo Scala Rider BT headset (mono) while on a motorcycle. The phone stays
in the saddle bag. My routine is to turn on the headset unit and then ask
for the time or battery life to verify operation. I have made calls by
pressing the button on the headset, waiting for the VC beep and stating the
name. After responding to the home, work, mobile question, the call is made.
I can answer calls on the Scala, which are announced by Contact name, by
saying 'answer', or pushing the button. (The answer via voice is a Scala
function, not a VC one). Hang up is automatic whether initiating or
answering.
I will comment that the Scala is not a cheap headset, with very good sound
and apparently great pickup and fidelity. My wife says I sound clearer on
the Scala on a bike going 50, than I do on the installed car handsfree in my
Jeep. So there may be some headset quality involved. Initially VC didn't
support BT because the fidelity of BT voice wasn't sufficient to ensure
voice recognition. I don't think BT got better, I think MS voice recognition
got better enough that they were willing to offer support. Doesn't mean
every headset provides sufficient fidelity.
I can of course not listen to music on the headset. I can request it, but
once the system initiates the media player it would expect to broadcast that
sound over a Stereo A2DP profile, which neither the K-Jam or the Scala
support. It just comes out of the K-Jam speakers. Not very satisfying when
the phone is in the saddle bags. ;) I have actually turned some of those
options off in VC support as each feature takes memory and processor effort.
I can't dispute that you can likely find lots of folks with issues on the
net, but for me it works as advertised and acceptably, within it's
constraints. Note that the units I use them on are official ROMs with the MS
BT stack.
