The SVS voice control system uses the microphone of the ”Telephone” function. The application of special noise-reduction processes improves the quality of the hands-free unit and voice input. Furthermore, it means that audio outputs (audio, video, navigation) can be issued simultaneously with lowered volume.
Pressing the PTT button (Push-to-Talk) on the multi-function steering wheel activates the request for input. Pressing once again cancels the dialogue guidance.
Control Display:With a few exceptions, the Control Display incorporates the controls and display elements for the body electronics. The Control Display coordinates the function requests from the system and assigns them to the relevant functions.
Visual feedback in the form of text display is provided on the Control Display. Here, an SVS status message is shown separately from the user input.
Controller:The Control Display is operated by means of the Controller located on the front centre armrest.
For dialogue guidance, the system can provide various outputs (sound, quality and voice of the voice output) that are stored in the voice command system. Everything that is highlighted in the Control Display, except for the heating and air conditioner functions, can be controlled using the SVS.
The MOST bus (Media Oriented Systems Transport) links the audio, video and navigation systems. Control commands, data and LF signals are transferred across the MOST bus.
Pressing the PTT button on the multi-function steering wheel sends the request to activate the function via CAN bus to the Control Display. The Control Display switches on the voice control system and the telephone functions by means of information via the MOST bus. This activates a microphone and the information path for the ”Telephone” function.
The voice control system is available in the following languages:
Faults can be pinpointed by selecting the redundantly stored data via the Control Display.
Help in operating the SVS can be displayed via the ”Menu” or ”Help”.
