Functional Principle of Voice Control System

System Start/End





The voice control system is activated/deactivated via the push-to-talk button (PTT) on the multifunction steering wheel or on the controller. For the first time, the PTT button on the controller makes it possible for the passenger to use the voice control system (SES). The SES is activated for the driver by briefly pressing the button and for the passenger by pressing and holding the button longer.

The SES is deactivated by again pressing one of the PTT buttons. Activation of the SES is indicated by a graphic display (PTT logo) in the status line of the CID. The system is active for about 5 seconds. If no input takes place during this period of time, the user is informed that no voice input was detected and the request for voice input is repeated. The voice control system is deactivated if again no input is made within 5 seconds.
