General tips for better speech recognition
Whether you are speaking commands or dialing numbers, background
noise may confuse the speech recognition system. In noisy situations,
the system may not recognize your commands. You will usually get
better performance from the system in quieter conditions. Here are
some common sources of vehicle noise:
• Air conditioner/heater fan – try turning the fan off temporarily
• Highway engine noise and strong winds – try slowing down or
waiting until you stop
• An open window – close all windows for better results
• Heavy rainstorms – you may have to wait until the rain subsides
• Passenger conversation – be sure passengers are quiet while
you speak commands
Helpful tips for Hands-Free Calling
• Speak as clearly as possible, and louder as necessary.
• You may have better results by speaking in a deeper,
lower-pitched voice, but try not to lower your volume.
• Avoid a rising intonation, such as when asking a question.
Use a falling intonation, as if giving an answer.
• Since everyone’s voice is unique, using different voice
techniques can help the system to work for you.
• For help with voice recognition, push the OnStar button .

General tips for interacting with the system
• The system does not recognize words such as “hundred,”
“thousand,” or “twenty.” Say each digit separately and
continuously. For example, the phone number “1.800.555.2030”
is pronounced “one-eight-zero-zero-fi ve-fi ve-fi ve-two-zero-three-zero.”
• You can also say, “911” and the system will dial 911.
