■Accessing voicemail and sending number tones to an automated
phone system
You can access a voicemail system and respond to a number request
from an automated phone system. When you receive the request for a
number while in a call, press the button after saying the numbers
one at a time, say “Dial”.
If you do not say any commands within 5 seconds after pressing the button,
or if you press the button twice, the system cannot receive the number tones
you are trying to send. Press the button to try again.
■ How to retrieve your phone number
Press the button. When the system responds with “Lexus
Link ready”, say “My number”.
The system responds with “Your number is [#]”.
If the response is “Per sonal calling unavailable”, this means your personal
calling feature is not yet active, this may take a few days from vehicle
delivery. It could also mean that the personal calling service is not avail-
able in your area. Press the butto n to check with an Advisor. Now
that you have your number, take a moment to practice by making your
first call to your home phone. Remember, the system recognizes numbers
better when you say them quickly.

■Speech recognition information
The Lexus Link speech recognition systems use speech technology that is designed
to understand a wide range of speakers of American English. However, the technol-
ogy may not work as well if a regional or ethnic accent is encountered. If the speech
recognition system does not work properly, refer to the following.
●The system does not recognize your command properly if noise is present. Per-
form the following to improve voice command recognition.
• Turn down or off the air conditioning system.
• Slow down to reduce wind noise.
• Close the windows and the moon roof to block outside noise.
• Have all occupants be quiet so that the system does not recognize their con- versation as a command.
●When to speak 
Say a command within 5 seconds after the system prompts you to speak.
●How to speak
• Speak forcefully and clearly.
• Speak calmly and naturally.
• The driver should speak while facing forward, and the passenger should
speak facing the inside rear view mirror.
• Avoid speaking with a rising intonati on. Use a flat or falling intonation.
●Tips for one-word commands
• The system recognizes only one word at a time for personal calling. (There
are some exceptions, such as “Advanced services” and “My number”.)
• When inputting the security codes or voice-activated keypad number, you
must say them one digit at a time. When inputting a phone number, the
speech recognition system can recognize 7, 10, and 11-digit numbers as well
as the number 911.

●Tips for entering a phone number using the “Dial” and “Store” commands
• You do not need to say “Dial”, “Store” or “Verify” after the phone number.
• If the phone number entered is not 7, 10, or 11 digits, use the “Dial” or “Store”
command.
• Do not pause between the digits.
• Speech recognition does not recognize the words “Hundred” or “Thousand”. Instead, say each digit.
• Speech recognition often works better when the digits are combined
smoothly into a single phrase.
• If the system does not recognize your command properly, use the “Digit dial” command to enter one digit at a time.
●If problems continue
• Say each one of the syllables in the word clearly.
• Be sure to articulate each sound in the word.
• If the system is confusing 2 commands th at are similar, be sure to pronounce
the distinction.
• Avoid clipping short words and syllables.
• Try speaking louder to prevent background noise from drowning out your
voice.
●Audible voice prompts
Some of the voice guidance instructions can be changed to Spanish. Press the
button and ask a Lexus Link Advisor.
