GF82.70-P-0002QA Voice Control System (VCS [SBS]), Function
- with CODE (813) Voice control system (VCS)


The voice control system (VCS) can be used to recognize both compound spoken voice commands which can be input without advance training i.e. independent of speaker as well as names specified and trained by the user in speaker-dependent mode The VCS contains high-performance noise reduction for suppression of environmental noise, so that a voice command is possible even at relatively loud driving noise. A distinction is made between the recognition of compound spoken words which are independent of the speaker and recognition of names and functions dependent on the speaker which the user defines and trains.
Data is transferred via the Controller Area Network bus class B (interior) (CAN-B) and the Digital Data Bus (D2B).

The VCS is activated or deactivated via the actuation of the VCS [SBS} switch (S93/2) which in the case of activation is signaled to the user acoustically by a beep and the case of deactivation via the voice output.
After activation the radio component of the respective audio system fitted in the vehicle is muted automatically. A noise reduction integrated in the VCS in addition to muting of the radio component of the respective audio system fitted in the vehicle should also help minimize fault detection by the VCS during voice input by the user. Here driving noise can be recognized by the VCS and can be suppressed as a result.
Moreover, voice recognition is activated once the VCS is activated.

Via the hands-free system microphone (B25) there is now the facility to operate the components of the respective communication or audio system fitted in the vehicle via accurately defined voice commands. Here the voice input should take place from the driver's side as the hands-free system microphone (B25) is set up for the driver's area.
The spoken announcement of the voice control system takes place via the vehicle's built-in speakers. Once the VCS is activated the volume can be adjusted via the volume controller of the respective audio system fitted in the vehicle. On vehicles with multifunction steering wheel (MFL) in addition the volume can be changed via the button + and -, adjustment of specific functions and and volume control (S111s1) on the multifunction steering wheel. A sound or volume setting is not possible at the voice control system control unit (A35/11). For manual volume adjustment a noise- dependent volume adaptation in 3 stages is used for the VCS voice output. It depends on the ambient noise level in the vehicle.

Furthermore, the VCS comprises a priority ruling, i.e. should collisions occur with respect to the operation of individual components of the respective communication or audio system fitted in the vehicle, then the functions started by the VCS are terminated or skipped.

Example
The navigation component of the respective audio system fitted in the vehicle would like to perform a voice output while the VCS is in dialogue with the user.
As the voice output of the navigation component of the respective audio system fitted in the vehicle has the highest priority of all the components of the respective communication or audio system fitted in the vehicle, the dialogue with the VCS is interrupted by the navigation component of the respective audio system fitted in the vehicle, the voice output of the navigation component of the respective audio system fitted in the vehicle takes place and the VCS returns to the dialogue with the user.
