CD, DVD or USB with Compressed
Audio Files (models with Navigation
System)
The file types supported by this system are MP3,
WMA, AAC/M4A and ATRAC3.
Explanation of terms● MP3 — MP3 is short for Moving Pictures
Experts Group Audio Layer 3. MP3 is the
most well known compressed digital audio
file format. This format allows for near “CD
quality” sound, but at a fraction of the size of
normal audio files. MP3 conversion of an
audio track can reduce the file size by ap-
proximately 10:1 ratio (Sampling: 44.1 kHz,
Bit rate: 128 kbps) with virtually no percep-
tible loss in quality. The compression re-
duces certain parts of sound that seem in-
audible to most people.
● WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft as an alternative to MP3. The WMA
codec offers greater file compression than
the MP3 codec, enabling storage of more
digital audio tracks in the same amount of
space when compared to MP3s at the same
level of quality. ●
AAC/M4A — Advanced Audio Coding
(AAC) is a lossy audio compression format.
Audio files that have been encoded with
AAC are generally smaller in size and deliver
a higher quality of sound than MP3.
● ATRAC3, ATRAC3 Plus — Adaptive Trans-
form Acoustic Coding (ATRAC) is a lossy
audio compression format developed by
Sony.
● Bit rate — Bit rate denotes the number of
bits per second used by a digital music file.
The size and quality of a compressed digital
audio file is determined by the bit rate used
when encoding the file.
● Sampling frequency — Sampling frequency
is the rate at which the samples of a signal
are converted from analog to digital (A/D
conversion) per second.
● Multisession — Multisession is one of the
methods for writing data to media. Writing
data once to the media is called a single
session, and writing more than once is called
a multisession. ●
ID3/WMA Tag — The ID3/WMA tag is the
part of the encoded MP3 or WMA file that
contains information about the digital music
file such as song title, artist, album title,
encoding bit rate, track time duration, etc.
ID3 tag information is displayed on the
Album/Artist/Track title line on the display.

Operating tips
To get the best performance out of the INFINITI
Voice Recognition system, observe the following:● Keep the interior of the vehicle as quiet as
possible. Close the windows to eliminate
surrounding noises (traffic noises, vibration
sounds, etc.) , which may prevent the system
from recognizing voice commands correctly.
● Wait until the tone sounds before speaking a
command. Otherwise, the command will not
be received properly.
● Start speaking a command within 5 seconds
after the tone sounds.
● Speak in a natural voice without pausing
between words.
Giving voice commands
To operate INFINITI Voice Recognition (VR) ,
press and release the
button located on
the steering wheel. After the tone sounds, speak
a command.
The command given is picked up by the micro-
phone, and voice feedback is given when the
command is accepted.
● If you need to hear the available commands
for the current menu again, say “Help” and
the system will repeat them. ●
If a command is not recognized, the system
announces, “Command not recognized.
Please try again.” Make sure the command is
said exactly as prompted by the system and
repeat the command in a clear voice.
● If you want to go back to the previous com-
mand, you can say “Go back” or “Correc-
tion” any time the system is waiting for a
response.
● You can cancel a command when the sys-
tem is waiting for a response by saying,
“Cancel” or “Quit.” The system announces
“Cancel” and ends the VR session. You can
also press and hold the
button on the
steering wheel for 5 seconds at any time to
end the VR session. Whenever the VR ses-
sion is cancelled, a double beep is played to
indicate you have exited the system.
● If you want to adjust the volume of the voice
feedback, press the volume control switches
(+ or -) on the steering wheel while being
provided with feedback. You can also use
the radio volume control knob.
● In most cases you can interrupt the voice
feedback to speak the next command by
pressing the
button on the steering
wheel. ●
To use the system faster, you may speak the
second level commands with the main menu
command on the main menu. For example,
press the
button and after the tone
say, “Call Redial.”
How to say numbers
INFINITI Voice Recognition requires a certain
way to speak numbers in voice commands. Refer
to the following rules and examples. ● Either “zero” or “oh” can be used for “0”.
Example: 1-800-662-6200
– “One eight oh oh six six two six two oh oh”, or
– “One eight zero zero six six two six two oh oh”
● Words can be used for the first four digits
places only.
Example: 1-800-662-6200
– “One eight hundred six six two six two oh oh”,
– NOT “One eight hundred six six two sixty two hundred,” and
– NOT “One eight oh oh six six two sixty two hundred”

TROUBLESHOOTING GUIDE
The system should respond correctly to all voice
commands without difficulty. If problems are en-
countered, try the following solutions.
Where the solutions are listed by number, try
each solution in turn, starting with number 1, until
the problem is resolved.
SymptomSolution
System fails to interpret the command correctly. 1. Ensure that the command is valid. For additional information, refer to “List of voice commands” in this section.
2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at a level appropriate to the ambient noise level in the vehicle.
4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster on) . NOTE: If it is too
noisy to use the phone, it is likely that the voice commands will not be recognized.
5. If more than one command was said at a time, try saying the commands separately.
6. If the system consistently fails to recognize commands, the voice training procedure should be carried out to im-
prove the recognition response for the speaker. For additional information, refer to “Voice Adaptation (VA) mode” in
this section.
The system consistently selects the wrong entry from the
phone book. 1. Ensure that the phone book entry name requested matches what was originally stored. This can be confirmed by
using the “List Names” command. For additional information, refer to “Phonebook” in this section.
2. Replace one of the names being confused with a new name.

USING THE SYSTEM
Initialization
When the ignition switch is placed in the ON
position, INFINITI Voice Recognition is initialized,
which takes a few seconds. When completed,
the system is ready to accept voice commands. If
the
switch is pressed before the initializa-
tion completes, voice commands will not be ac-
cepted. Please wait until the INFINITI Voice Rec-
ognition initialization is completed.
BEFORE STARTING
To get the best recognition performance from
Voice Recognition, observe the following:
● The interior of the vehicle should be as quiet
as possible. Close the windows to eliminate
the surrounding noises (traffic noise and vi-
bration sounds, etc.) , which may prevent the
system from correctly recognizing the voice
commands.
● Wait until the tone sounds before speaking a
command.
● Speak in a natural conversational voice with-
out pausing between words.
● If the air conditioner is set to “Auto”, the fan
speed is automatically lowered so that your
commands can be recognized more easily.
GIVING VOICE COMMANDS
1. Press theswitch located on the steer-
ing wheel. 2. A list of commands appears on the screen,
and the system announces, “Would you like
to access Phone, Navigation, Information,
Audio or Help?”
3. After the tone sounds and the icon on the screen changes from
to, speak
a command.
4. Continue to follow the voice menu prompts and speak after the tone sounds until your
desired operation is completed.

a command.
4. Once a command is recognized, the system will announce the recognized command and
perform the requested action.
If the command is not recognized, the sys-
tem repeats the announcement. Repeat the
command in a clear voice after the tone.

Symptom/error messageSolution
Displays “COMMAND NOT RECOG-
NIZED” or the system fails to interpret
the command correctly. 1. Ensure that the command format is valid, refer to “Standard Mode command list” or “Alternate Command Mode command list” in this
section.
2. Speak clearly using your normal speech pattern and at a level appropriate to the ambient noise level.
3. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.
NOTE:
If it is too noisy to use the phone, it is likely that voice commands will not be recognized.
The system consistently selects the
wrong voicetag in the phonebook. 1. Ensure that the voicetag requested matches what was originally stored. For additional information, refer to “Bluetooth® Hands-Free
Phone System with Navigation System” in this section.
2. Replace one of the voicetags being confused with a different voicetag.
