    I have installed a microphone... Can I do any voice commands in Driveline?

    Yesterday I installed one of those expensive Andrea 350 array microphones, and was playing with windows speech recognition features. I tried to get it to do something in Driveline, but it did not recognize any of my commands, and I am not sure that the Driveline screen was even in the focus of Driveline, it may have been stuck at the desktop.

    I configured the microphone to not play what it hears, because that messes with the background music. There is a little window that listens to what I say, and even if music is playing, it can hear what i am saying because of where the array is placed on my sun visor.

    Are there any voice commands built into Driveline?

    Things I would like to do are:

    Turn On/Off Phidget Digital Outputs
    Turn On Camera #1-5
    Next track/Previous Track
    Volume Mute/Resume
    Volume Atteunate/Resume
    and more.

    DriveLine does support voice commands. When I implemented voice commands in DriveLine, I experimented with an 'always listening' mode, but I felt like it wasn't reliable. So, to trigger DriveLine to start listening, perform a long-hold on the status-bar. The music will pause for a few seconds while you speak a command. I could probably add a Config setting to enable 'Always Listening' mode. I've got some other ideas for how to make it easier to use too. But the basic functionality is there.

    For skin-specific commands, look for
    Skin_SkinVoiceCommands.xml in the skin folder.

    For generic DriveLine commands, look for
    DriveLine_VoiceCommands.xml in the Settings folder.

    I recommend testing both.

    Thanks Clock, that gives me lots of stuff to play with. I'll report my results.

    I was not able to long hold the status bar with my finger or stylus because the touchscreen only lasts a second or 2 then the highlighting goes away. So I tried with a keyboard and at about 2-3 seconds the music will mute. I could not get any of the commands listed to respond though. The speech flyout does not show, but when I said start listening, I heard it beep in response.

    I will spend some more time messing with it, but is there a way to change the long hold time on the status bar?

    The voice-command functionality will not display any fly-out. It uses Windows built-in speech recognition. (To be clear, it's built into Windows Vista and later. For WinXP, you need to install MS Office.) You will probably need to configure/train Windows Speech Recognition before it will work reliably.

    If a long-hold is not working with your touch-screen, you may have the touch-screen software configured to turn a long-hold into a right-click. There is currently no config setting to adjust the long-hold duration.

    You should be able to perform a long-hold on the navbar with a mouse to test. After a few seconds, the music will pause. Try speaking 'computer toggle dimmer' or 'computer close driveline'. These two commands are defined in the generic 'DriveLine_VoiceCommands.XML' file.

    In the next test version, there will be an icon you can add to the home-screen which will trigger voice-command listening with just a normal click. The icon will be grayed out if speech-recognition is not available. I will look into adding the 'Always Listening' option as well.

    I think I found a bug in the voice command code, causing it to not match voice-commands to speech. I'll get you a new version to test tomorrow.

    Ironically, the problem was caused by some extra error-trapping that I put in.
