Voice Control introduction
Spelling
You may not need to spell the entire name
(street, intersection, city or point of inter-
est) especially if the name is lengthy. Spell-
ing the first three to five characters of the
name should be sufficient for the system
to recognize the name provided it is avail-
able on the navigation DVD.
The selection appearing on the COMAND
display is sorted based on your recognized
voice input and a matching algorithm.
You can use the commands “Next page” or
“ Previ ous p ag e” t o sc roll up or down in the
list.
Use the command “Correction” to start
over by again spelling the name.
Speak each character as clearly as you
can, especially when they sound very simi-
lar (d or e).Command types
The Voice Control System commands can
be categorized as:
General Commands
These are commands always available
to you as soon as the Voice Control
System is activated (for example
“Help” commands).
Local Commands
These are commands specific to the
currently active system shown in the
COMAND display (for example com-
mands to control the CD changer).
For a complete list of commands
(
page 305).
Active System
The active system is the system currently
shown in the COMAND display.
If, for example, you listen to the radio while
the telephone system is active on the
COMAND display, you have to switch to
the radio using the command “Radio” be-
fore you can operate the radio.
iDuring Voice Control System operation visu-
al help windows also appear in the COMAND dis-
play (

ters at a time.

Voice Control troubleshooting
ProblemPossible cause/consequenceSuggested 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
(
