274 Control systems
Voice Control introduction
The Voice Control System gives you the ca-
pability to control the following systems on
your vehicle using spoken commands:

Telephone* (page 278)

Navigation (page 285)

Address book (page 295)

Audio (page 299) (AM/FM radio,
CD/DVD changer, MP3 player)You control these systems using spoken
commands. Moreover, controls such as
the buttons on the multifunction steering
wheel (
page 276) allow you to keep your
hands on the steering wheel.
The command vocabulary consists of
approximately 300 ready to use phrases.
The Voice Control System recognizes com-
mands and number sequences, irrespec-
tive of the speaker. To optimize speech
recognition for your voice follow the indi-
vidualization process (
page 320).
You can use the Voice Control System to
call up all of COMAND’s main menu items,
with the exception of the main menus for
“Vehicle” and “Navi”.The commands and digit sequences can be
spoken without pausing between the indi-
vidual words. If an unavailable or incorrect
command is used, the Voice Control Sys-
tem will prompt you for a new command by
asking “Please repeat” or “Please repeat
your entry”.
In order to provide for a safe and comfort-
able dialog, the Voice Control System ac-
knowledges important commands.

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
