: 2008 Cadillac Navigation VR-Voice Recognition

Any advice on how to get the voice recognition of the navigation system to work correctly? The VR doesn't respond and acknowledge my voice when I use any of the voice commands from the user manual. Example, trying to make a hands free phone call using the bluetooth feature, I press the talk symbol on the steering wheel until I hear a beep. Next I give the phone command, (telephone enter) but the VR voice responds with pardon and then it will say command not recognized. Is there an equipment fault with the Navigation system for the 2008 STS year model.

The secret. Make sure you have selected an announcements voice that matches your gender.

I tried every know voice known to man in an attempt to make mine on my 2010 1SC. Bottom line is doesn't work well. Type it in manually.

Unfortunately, the system wasn't really ready for the real world, but there are some ways to make it work a bit better. The Nametags can work, probably because the system is attempting to match to your own voice rather than a generic voice. Just after I bought mine, I sat in the car for about an hour playing around to learn it and record Nametags.

You already heard several members suggest sekecting a voice that matches your sex. Louder isn't better. State commands distinctly at a normal pace. Don't run them together or slow down. (Never Yesss or Nooo.) If the HVAC fan is running over low, turn it down.

Use the right commands. Check the Nav manual addendum or press the VR button and say 'Navi Help'. I use 'Phone Dial Name' and the Nametags quite a bit. For the rest, I'd rather use a Lockpick and let my passenger use the system as designed.

There is a firmware upgrade available for 2005-07. It reduces the number of commands and helps a bit in other ways, too. If you've got the 2008 & up, I don't think there's an upgrade available.

by far the crappiest feature on this car :banghead: wish I could rewire the button to do something else instead like activate the lockpick

The VR isn't ready for prime time but it can improve with practice and the pointers forum members offer.

The problem is that it IS ready for prime time. Cadillac had it done right in 2002 in the DVD Nav in the Seville / Deville lines and I believe the 04 srx and possibly 03 CTS use the same Nav unit. VR worked 98% of the time then. Why on a "more advanced" Nav is it terribly broken?

Pardon? :)

Sorry, had to do it...

Personally, my theory is based on how the vehicle is wired.

To start, voice commands are stored on the navigation DVD. Without the disc, VR doesn't work. I have also read supporting technical documentation that indicates spoken commands are compared against those stored on the disc. This would suggest that if it were a recognition problem, they would be able to "tweak" the DVD data in future disc releases to correct/improve VR.

Another possibility is the quality of A/D (analog to digital) conversion hardware built into the radio. Again, I'm not sold on this as chips/technology by the time 2005 rolled around were actually pretty good. This however is where a firmware upgrade could improve things. As of 2008, it's probably about as good as it's going to get in the particular radios we have.

My number one theory relates to the fact that the VR microphone is shared with OnStar. The mic in the mirror is connected to the VCIM (Voice Communications Interface Module / OnStar) located in the far right rear corner of the car. When you activate the VR feature, the VCIM redirects the audio signal back up to the navigation radio in the front of the car. This is a fairly lengthy route for an audio signal of only millivolts to travel through a marginally shielded cable physically located in a wiring harness laden with other electrical noise. I suspect that if there was a separate microphone, connected directly to the navigation radio and electrically shielded adequately, recognition would be much more accurate.

Just my thoughts.

Voice recognition will now be canceled :)

My advice: Turn down the HVAC fan, use a normal tone of voice, no louder. Don't stretch words, even speak briskly. Record nametags... 'Phone dial name' worked perfectly for me today.

From the Nav manual:

Helpful Hints for Stating Commands
• When a multiple command is available, choose the
command that best works for you.
• Words that are in brackets are optional. For example,
for the command Radio [band] [select] FM, stating
Radio FM or Radio select FM are both valid
commands.
• When the system recognizes the command the
system will:
• either perform the function
• ask you to confirm your choice by clearly stating
“yes or no”
• issue an error message such as “System does not
recognize this command” or direct you to “Please
start speaking after the beep”
• If the system is not yet ready, the system may state
“System is checking the disc. Please wait.”.
• To cancel a command or if the system response
does not match your verbal command, press and
hold the talk symbol button. The system will reply,
“System will cancel the voice recognition”.
• If you experience difficulty with the system
recognizing a command, try saying it more softly,
and wait for a few seconds after the beep, or you
may just try saying it again.
• Background noise may cause voice commands to be
misunderstood, including airflow noise from wind.
• To use the voice recognition system, the map DVD
must be loaded.
This system is able to recognize commands in five
different languages. The system will only recognize
commands based on the language selected.

Voice Recognition Help
Help commands can be displayed on the screen while
you are stopped. When the vehicle is moving, the system
will let you know that this command is not available while
driving. To enter the help screens, clearly state one of the
help commands.

Navigation [command] help, navigation [command]
list: This command instructs the system to state the
navigation command help list.

While in the help menu, you can select from two
screens, the Command List and the Operating Guide.
The Command List shows a list of available voice
recognition commands to use. Touch the Command List
screen button and then touch one of the buttons on the
right of the screen to choose the commands to view.
Use the up and down arrows to scroll through the list
of commands.

short answer

dont use it....its a terrible system that never worked

Its the worst system I have ever seen

However...the STS was/is the least expensive luxury car to buy

so...that being said

be satisfied as you didnt pay for a Lexus GS.....IMO...the best Nav system of that time peiod
