    I assume you are referring to the duh-duh-da! that plays when I hit the green button. I swiped the audio files from voicecmd.exe, the voice program on my pocketPC. But I didn't want them to be identical so I doubled up the first "duh".

    I've attached the file to this post.

    The camera is a cheapo little NTSC video camera -- $25 at Tiger Direct. Then, I've got a $40 super-wide lens on it. Finally, to show the image, it's connected to a USB TV Tuner "MSI VOX BOX" that I bought years ago and don't really use anymore. To actually display the image, I use Flash -- it's super easy and more importantly, it makes mirroring the image really easy (since you want it to be mirrored, like your rear-view mirror is).

    Cheers,

    Thanks a lot. I got centrafuse to react the same way as you have ur setup except for one minor flaw... I haven't quite figured out how to make it chime again when the voice command ends. I should be able to figure it out soon. Thanks for all assistance

    does the camera turn on when you shift the gear to reverse or did you have to press a command?

    wow, that is an excellent setup.

    I've given up on a solid voice command but you have peaked my interest again!

    Could you elaborate a little more on your voice command? I would like to have a push button activation but I don't understand the relay part...


    Again, awesome system!

    When I switch into reverse gear, a small relay that is connected to my rear reverse lights activates, telling the computer (via the Arduino board) that I am in reverse. The camera appears automatically. It disappears when you're no longer in reverse, after you drive at a speed of more than 8 km/h (so if you are going back and forth, back and forth, the camera doesn't keep appearing and disappearing like some cars)

    Could you elaborate a little more on your voice command? I would like to have a push button activation but I don't understand the relay part...
    Certainly. The pushbutton simply trips a small relay, also connected to the Arduino board. This tells the computer that I've hit the button. It pauses the music, plays the "duh-duh-dah!" sound, then mutes the system (in case some other app is making noise) and activates the voice command "listener".

    If you don't say anything within 4 seconds, or it doesn't recognize you within 10 seconds, it plays the "buh" noise, unmutes the audio, and resumes the music.

    If it recognized a command (depending on the command), it issues a verbal confirmation and then executes the command. If you hit the button again while it is speaking the confirmation, it instantly aborts. This is so that if it misheard you, you can cancel it and try again.

    I did all of this with the Microsoft Speech API SDK (free download from Microsoft) and VB6.

    Thanks for your interest!
