114Speech recognitionSpeech recognitionGeneral information...................114
Phone control ............................ 115General information
The speech recognition of the
Infotainment system enables you to
operate the phone portal via voice input. It recognises commands and
numeric sequences independently of
the current speaker. The commands
and numeric sequences can be
spoken without a voice pause
between the individual words.
You can save telephone numbers
assigning a name of your choice
(voice tag). Using these names, you
can later set up a telephone
connection.
In the event of incorrect operation or commands, the speech recognition
gives you visual and/or acoustic
feedback and requests you to re-
enter the desired command. Apart
from this, the speech recognition
acknowledges important commands and will enquire if necessary.
To ensure that conversations inside
the vehicle do not lead to
unintentional triggering of systemfunctions, the speech recognition
does not start until it has been
activated.
Important notes on language
support ■ Not all languages available for the display of the Infotainment system
are also available for the speech
recognition.
■ If the currently selected language for the display is not supported by
the speech recognition, you must
enter the voice commands in
English.
To be able to enter voice
commands in English, you must
first activate the phone main menu
by pressing the PHONE button on
the Infotainment system, and then activate the speech recognition of
the phone portal by pressing button
w on the steering wheel.

With the aid of the speech recognition
the mobile phone can be operated
very conveniently via voice input. It is
sufficient to activate the speech
recognition and to enter (say) the
desired command. After input of the
command the Infotainment system
guides you through the dialogue with
appropriate questions and feedback
to achieve the desired action.

recognition a short tone signals that
the speech recognition is expecting
input.

Entering a telephone number
After the command " Dial" the speech
recognition requests input of a
number.
The telephone number must be
spoken in your normal voice without
any artificial pauses between the individual numbers.
Recognition works best if a pause of
at least half a second is made after
every three to five digits. The
Infotainment system then repeats the
numbers recognised.

■ " Help "
■ " Cancel "
The maximum length of the telephone number entered is 25 digits.
