Cadillac STS Forum - 2005 through 2012 Discussion, STS Voice Commands Voice Recognition Issues in Past Cadillac Vehicle Discussion; I just bought a 2009 STS and I haven't had any luck trying to get the voice commands to work. ...
I just bought a 2009 STS and I haven't had any luck trying to get the voice commands to work. I have the button on the right side of the steering wheel. I press button, guy says speak after beep or whatever and after I speak, he says pardon? He does it a couple more times and then says command not reconized or something like that.
It takes some practice and isn't really ready for the real world.
1. Make sure the windows are up & the fan is low or off.
2. Speak softer, not louder.
3. Do not stretch out your words.
4. Some members claim that people who speak in a higher register should set it to the female voice.
5. 'Navi Help' will display the commands.
6. The Nav firmware upgrade does help (but it's still this cars weakest feature).
It's generally terrible. In your case, there is no firmware upgrade (your STS is too new and will have the most recent version). It takes a lot of practice and most people find it just isn't worth the effort. Too bad, because it's a nice idea.
Voice commands are stored on the map DVD. I wish they would work a little bit on this because it should be possible to make improvements. Given that the car is now out of production, I wouldn't hold my breath that this will ever happen.
Male users should select the male voice option. Female users should select the female option. GM has issued an information bulletin suggesting this may improve performance. Don't get too excited though, it won't magically fix all the VR problems with this system.
