tem contains an extensive help function.
The help function gives you:
General hints on how to best use the
Voice Control System
A listing of all available commands
Help commands
“Help voice control”
Using the command “Help voice control”
will give you information on how to best
use the Voice Control System.
“Help”
In a main menu, help can be accessed at
any time by saying the command “Help”.
The Voice Control System will then read
out the available functions and commands
of all systems.In a submenu, help can also be accessed at
any time by saying the command “Help”.
The Voice Control System will then read
out an option list of all available functions
and commands available in the particular
submenu.
You can also use the help function to ac-
cess help for a specific system. To access
help for the phone operation, you would
speak the command “Help Telephone”.
If you wish to execute the last command
read out:
Press!.
Help window
You can use the help window to view a se-
lection of valid commands on the
COMAND display.
The help functions can be switched on or
off via COMAND in the “System settings”
menu (
page 261).
Entering digits and spelling
Entering digits
Digits from “Zero” to “Nine” may be
used.
Speaking phone numbers in digit
blocks of 3 to 5 digits has proven a
very reliable method for the input of
phone numbers.
Spelling
The letters of the English alphabet and
the digits 0 - 9 may be used.
Speak the letters in blocks of 5 - 7 let-
ters at a time.
Speak each individual letter clearly.

Voice Control troubleshooting
What to do if ...Problem
Possible cause/consequence
Suggested solution
Voice Control System does not recognize a
station list entry.
The voice entries for the station names
sound too similar.
When you create your address book en-
tries, select names with the greatest
possible acoustic differences.
Speak the command “List station list”.
The system reads out the station list en-
try by entry.
Press ! when the desired station
name is being read out.
The station is selected (
page 336).
Should interference occur during the pro-
cess of storing a name, the Voice Control
System prompts you to repeat your voice
entry a third and fourth time. If the interfer-
ence continues, the dialog is stopped.
Both voice entries differ.
Pronounce the voice entries both times
in the same manner.

354 Control systemsVoice Control troubleshootingProblem
Possible cause/consequence
Suggested solution
Voice Control System does not recognize
commands.
You have not operated the system from the
driver’s seat.
Operate the Voice Control System only
by the driver as the microphone is
geared to the driver side.
You have spoken unclearly, too loudly or
too quietly.
Speak the commands in a continuous
manner using a normal tone.
A blower is set to the highest setting, vents
are pointed at microphones or wind noise is
being created through open windows.
Avoid loud disturbances.
Voice Control System does not recognize a
address book entry.
The voice entries in the address book sound
too similar.
When you create your address book en-
tries, select names with the greatest
possible acoustic differences: If for ex-
ample you have the names Smith and
Schmidt, choose for example “Smith
work” or “Schmidt John”.
Speak the command “List phone book”.
The system reads out the address book
entry by entry.
Press! when the desired entry is
being read out.
The entry is selected and the corre-
sponding number is dialed
(page 319).

355 Control systems
Voice Control individualization
Voice Control individualization
The individualization is used to adapt the
Voice Control System to your own voice
and to therefore improve speech recogni-
tion. This does not affect the speech rec-
ognition of other users.
Individualization consists of two stages:
Digits
Commands
You can activate individualization in the
COMAND system settings (
page 261).
A dialog and screen displays will guide you
through the individualization process.
The system can be reset to the factory set-
tings at any time.
i
The individualization can only be performed
when the vehicle is stationary.
If you drive off, the individualization will be can-
celed.
After starting the session, the system will guide
you through the individualization by means of
acoustic instructions.
i
You may wish to complete only a portion of
the individualization process.
Completing the digits portion alone may result in
an improved recognition rate.
Individualization can be exited at any time. The
data trained, however, will only be retained if a
given individualization portion is completed and
the data is stored when prompted to do so by the
system.
