Circuit/System Description

The CIM is capable of interpreting voice commands received over the cellular microphone circuits. Speech recognition allows the user to speak to one computer in the vehicle, and one reached over the cellular communication network. The module attempts to understand the users command, and responds by speaking back, or by taking the appropriate action, e.g. dialing the phone.

Circuit/System Verification

Important:
* It is necessary to have the vehicle in an open outside area where a cellular call can be successfully placed and GPS data can be received from satellites.

* The vehicle should be located in a quiet area.

1. Ignition ON, press OnStar(R) Call button. Verify that your voice is heard clearly by the OnStar(R) Call Center.

2. Press the OnStar(R) Call answer button. Attempt to operate the OnStar(R) system using multiple different voice commands. Verify the system responds appropriately to all voice commands.
