Location 

The voice control system (VCS [SBS]) control unit is installed under the left rear seat.

Task 

The purpose of the voice control system (VCS [SBS]) is to relieve the user during driving and to provide him/her access to a series of functions without diverting his/her attention from the traffic situation. The voice control system (VCS [SBS]) control unit is used to control the communication components and navigation systems installed in the vehicle within the framework of an integrated communication and audio system.

Function 

The voice control system (VCS [SBS]) control unit recognizes and processes commands that are spoken together and entered independently from the speaker and also names specified and trained by the user.

The following functions can be operated:

Noise reduction 

If the voice recognition feature of the VCS [SBS] is active, the driving noise of the vehicle can be filtered out of the microphone signals to the greatest extent possible by means of a noise reduction module. In the process, the hands-free speaking quality is also improved significantly.

Echo compensation 

Since feedback can occur during voice output (disturbing echo), the voice control system (VCS [SBS]) control unit is equipped with echo compensation which acts in both directions (full duplex).
