■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.
