IN CASE OF AN EMERGENCY VOICE COMMANDS / SPEECH RECOGNITION Operation of the Lexus Link speech recognition systems: Speech recognition allows the user to speak to a computer. The computer tries to understand the user's command, and responds by speaking back or by taking the appropriate action (e.g., dialing the phone). Personal calling uses a speech recognition system that is built in the vehicle. When the user presses the phone or PTT button, the system says "Lexus Link ready", and listens for the user's command. The user can speak commands to control the hands−free wireless phone. Performance of speech recognition: The Lexus Link speech recognition systems use speech technology that is designed to understand a wide range of speakers of American English. However, the technology does not work equally well across all regional and ethnic accents. The Lexus Link voice recognition system may not work with all voices. Although there is no one right way to speak English, the system will work best when you try to modify their pronunciation in response to system errors. If you do not obtain good results, try the tips found on the following pages. Voice command error messages: "Pardon" The system has not been able to match your command with a word that it knows. Repeating the command distinctly should fix the problem. After 3 pardon responses, the system will try to guess the command you are requesting. If correct, say "Yes", if not, say "No" and the system will prompt you with its next−best guess. "Slower, please" Repeat the command after a short pause. This response normally happens if you say a command before the system is ready for it or if there is substantial background noise. 474
