176 Infotainment System
Hybrid Speech Recognition
If equipped, this feature helps distinguish
words by using Internet-based information
along with the system s voice recognition
database. This allows you to speak more
naturally when using voice recognition.
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 on the steering wheel controls
to activate voice recognition.
2. The audio system mutes and the system
plays a prompt.
3. Clearly speak one of the commands
described in this section.
A voice recognition system prompt can
be interrupted while it is playing by
pressing again.
Once voice recognition is started, both the
infotainment display and instrument cluster
show the selections and visual dialog
content. These displays can be turned on or
off in the Tutorial Mode under Settings
0 186.
There are three voice prompt modes
supported:
Informative verbal prompts: This type of
prompt will provide more information
regarding the supported actions.
Short prompts: This type of prompt will
provide simple instructions about what
can be stated.
Auto informative prompts: This type of
prompt plays during the first few speech
sessions, then automatically switches to
the short prompt after some experience
has been gained through using the
system.
If a command is not spoken, the voice
recognition system says a help prompt.
Prompts and Infotainment Displays
While a voice recognition session is active,
there may be corresponding options
showing on the displays. A selection can be
made by manually touching the option,
or by speaking the number for the option to
select. Manual interaction in the voice
recognition session is permitted. Interaction
during a voice session may be completed
entirely using voice commands while some
manual commands may expedite a task. If a
selection is made using a manual control,
the voice recognition dialog will progress in
the same way as if the selection were made
using a voice command. Once the system
completes the task, or the session is
terminated, the voice recognition dialog
stops.
An example of this type of manual
intervention is touching an entry of a
displayed number list instead of speaking
the number associated with the entry
desired.
Canceling Voice Recognition
Touch or say Cancel or Exit to
terminate the voice recognition session
and show the display where voice
recognition was initiated.
Press on the steering wheel controls
to terminate the voice recognition session
and show the display where voice
recognition was initiated.
Natural Language Commands
Most languages do not support natural
language commands in sentence form. For
those languages, use direct commands like
the examples shown on the display.
