Voice Recognition
If equipped, voice recognition allows
for hands-free operation within the
audio and phone applications. This
feature can be started by pressing
either the
gbutton on the steering
wheel or by selecting the
gon the
screen display.
However, not all features within
these areas are supported by voice
commands. Generally, only complex
tasks that require multiple manual
interactions to complete are
supported by voice commands.
For example, tasks that take more
than one or two button presses such
as selecting a song or artist to play
from a media device would be
supported by voice commands.
Other tasks, like adjusting the
volume or seeking up or down are
audio features that are easily
performed by pressing one or two
buttons, and are not supported by
voice commands. In general there are flexible ways to
speak commands for completing the
tasks. Most of them, except
destination entry and voice keypad,
can be completed in a single
command. If the task takes more
than one command to complete, the
first command would be to indicate
the kind of task that is to be
performed. The system replies with
prompts that lead through a dialog
to enter the necessary information.
Voice recognition can be used when
the ignition is on or when Retained
Accessory Power (RAP) is active.
See
Retained Accessory Power
(RAP) on page 9-28.
Using Voice Recognition
Voice recognition becomes available
once the system has been
initialized. This begins when the
ignition is turned on. Initialization
may take a few moments. 1. Press
gon the steering wheel
control to activate voice
recognition, or select
gon the
infotainment screen on the
center stack.
.If voice recognition is started
from the steering wheel
control, the instrument
cluster displays the
selections and visual dialog
content.
.If voice recognition is started
from the infotainment screen,
the selections and visual
dialog content are displayed
on both the center stack
display and the instrument
cluster display.
2. The audio system mutes and the system plays a prompt followed
by a beep.

7-26 Infotainment System
For best results:
.Listen for the prompt and wait
for the beep before saying a
command or reply.
.Say“Help” or look at the screen
display for commands.
.Voice recognition system prompt
can be interrupted during a
prompt by pressing
gagain.
For example, if the prompt
seems to be taking too long to
finish, or if what is being
prompted causes a need for an
immediate reply, press
gagain
and wait for the beep.
.Speak the command naturally,
not too fast, not too slow. Use
direct commands without a lot of
extra words.
.Usually Phone and Audio
commands can be spoken in a
single command.
For example, “Call Dave Smith
at work,” “Play” followed by the
artist or song name, or “Tune”
followed by the radio station
number.
There is no need to memorize
specific command words. Direct
commands might be more clearly
understood by the system. An
example of a direct command would
be “Call 555-1212.” Examples of
these direct commands are
displayed on most of the screens
while a voice session is active.
If “Phone” or“Phone Commands,” is
stated, the system understands that
a phone call is requested and will
respond with questions until enough
details are gathered.
If the phone number has been
saved with a name and a place, the
direct command should include
both, for example “Call Dave Smith
at work.”Using Voice Recognition for
List Options
When a list is displayed, a voice
prompt will ask to confirm or select
an option from that list. A selection
can be made by manually selecting
the item, or by speaking the line
number for the item to select.
When a screen contains a list,
options may be available but not
displayed. The list on a voice
recognition screen functions the
same as a list on other screens.
Scrolling can be used to help
display other entries from the list.
Manually scrolling or paging the list
on a screen during a voice
recognition session suspends the
current voice recognition event and
plays the prompt “Make your
selection from the list using the
manual controls or press the Back
button to try again.”
If manual selection takes more than
15 seconds, the session terminates
and prompts that it has timed out.
