GF82.70-P-0002B Voice Control System (VCS [SBS]), Function

MODELS 140, 202,203 up to 23.4.04,208.3, 210,215, 220 up to 31.8.03
- with CODE (813) Voice control system (VCS)

Function
Up to 31.5.00 the voice control system (VCS) in models 140, 202, 208.3, 210, 215, 220 is a functional extension of the existing telephone system with hands-free system.
As of 1.6.00 the voice control in models 202, 208.3, 210, 215, 220 as for model 203 is extended to include the existing audio systems. With VCS, it is possible to operate the car telephone or audio systems by voice without taking the hands from the steering wheel.
The data transfer is:
- Analog/digital via Controller Area Network (data bus/CAN bus) (CAN) in Models 140, 210 up to 5/31/98
- Analog/digital via CAN and digital data bus (D2B) in Models 202, 203, 208.3, 210 as of 6/1/98, 203, 215, 220

Activation or deactivation are accomplished by actuating the VCS switch (S93/2). The user is acoustically informed of the activation through a beep and in the event of deactivation via voice output. After an activation all audio sources that can be influenced are automatically muted. The integrated functions for noise reduction are intended to help minimize the error recognition rate of the system during voice entry by the user. This allows driving noises to be recognized by the system and ignored. Moreover, after activation of the VCS, voice recognition is activated.

Via the handsfree system microphone (B25), it is also possible to operate the systems using precisely defined spoken commands. Here, voice input should be accomplished from the driver's side because the handsfree system microphone (B25) points toward the driver.

Voice output can be adjusted using the volume control of the particular vehicle specific component of the audio system. On models 203, 208.3, 210, 215 and 220 with multifunction steering wheel (MFL) it is also possible to adjust the volume with the + and - buttons for adjustment of special functions and volume control (S111s1). In addition to the manual volume setting, a noise-dependent volume control with 3 stages is present for voice output by the VCS. This is dependent on the ambient noise in the vehicle. It is not possible to adjust the tone.

The VCS also contains a priority control, i.e. should higher, prioritized messages be issued by the voice input during the operation of individual components of the communication or audio system, then the functions started by the VCS are interrupted or skipped.
