I can't really answer from a sprint perspective, I have the Fuze. Voice Command works fine for me. I mainly only use it for bluetooth though and activate it through my headset. On the Fuze we have a PTT button that can be remapped and I have done that for using the handset to activate it.
My question had more to do with whether WM 6.1 had a problem with Voice Commander or vice versa. MS Voice Commander is one of those programs which probably won't care if the phone is a Verizon or a Sprint device.
This is interesting! Despite the fact that the Voice Command program allegedly works on the Touch Pro, the Handango, Handmark, and PocketGear websites (which are the linked-to distributors from the Microsoft Website) says the device is not compatible. It won't even let you buy the software if you have the HTC Touch Pro listed as your device.
Now here's the real kicker, and great news for Sprint Touch Pro users: Sprint calls the program "Automatic Speech Recognition (ASR)" and it's pre-installed and ready to run. You simply hold down the talk button for a couple of seconds, a microphone icon appears in the status icons area at the top of the screen, the phone beeps, and you say the name of who to want to call. If you have a Bluetooth headset active, pressing the button on the headset does the same thing and my Blaupunkt car stereo (Bluetooth hands-free enabled) works just as well.
I don't care what Sprint calls it, it's Microsoft Voice Command (looks like a duck, quacks like a duck, etc). No training required; just start using it.
I guess there are some advantages to reading the instruction booklet after all.
Just an FYI, you can also use Voice Command to open Windows Media by saying open Media, or say play music, ask it what your next appointment is...many things.
I am SOO glad that Sprint has added this to the phone. I bought the first VC program about 8 years ago and have been a big fan. No training needed. If you tell it to call someone and there are several numbers, it will ask you which one.
