Ok I have a moto G cell phone and I have a moto H300 bluetooth.. All I need to know is what voice commands do I use to work it

There are different sound levels for different events in your phone..
Ringer being loud does not mean Notifications and media is high.
Is your notification sound turned up?

There's a site that recommends trying a variety of different things to fix this issue on different makes & models of phones..
like Turn off your bluetooth
OR Turn on bluetooth and turn up radio.. check it out:

Not sure of HBS-700 capabilities. You might have to touch the phone to start it listening. Though I would be surprised that based on how you press buttons on headset might initiate voice command.

Corded headsets do not have Bluetooth. Do you have a Bluetooth headset (wireless) handy to test the Bluetooth function properly?

Delete the coupling and re-couple again waiting that all the services for the AUDIO DEVICE are added.

Hi bredebar you need to go to settings. Next you need to hit the wirless &network go to the bluetooth settings and make sure that the blue tooth is connect to the phone and audio. If your having a problem with the voice command it is because your ally doesn't have froyo on the ally. You need that to get the voice commands to work. you can go to the open market and put in voice commands for droids. Hope this helps foryo is frozen yogurt great name. There is another new program coming out be on the lookout for it .

Voice Command is not supported on the 1st Gen or 3G iPhone even with the 3.0 software update. The new iPhone 3GS does support Voice Command. See here for more info on it.

Voice command is activated by the side button that is alone (right side if your facing the phone's screen) when the phone is closed. I don't know how to prevent the phone from doing that, but I do know how to make sure the phone does not say "Please say a command."

Menu
Settings and Tools (Far right icon)
Tools (#2 on the list)
Voice Commands (#1 on the list)
Hit settings, which is going to be the right bumper button (above the CLR key)
Go to prompts (#5 on the list)
Mode (#1 on the list)
It will be currently set on prompts, which is why it says "Please say a command." You can either set it to readout or tones only. Tones produces a short beep. Readouts only displays text (no noises). Being that you have your phone on silent, I assume you want readouts.

That will at least prevent stop the phone from making random statements in your pocket. Hope this helps.

Try going to Menu > Contacts > Voice Command

Moto H300 should be "0000"
