General tips for better speech recognition:
<Noise>
Noise may confuse the speech recognition system.
usually get better performance from the system in quieter
conditions:
D The air conditioning/heater fan creates noise. Turn it down
or off for better speech system performance.
D Driving at high speeds creates louder engine noise and wind
noise. You may get better results at lower speeds.
D An open window or an open moon roof results in more noise
in the vehicle. Close all windows for better results.
D Noisy rainstorms can also reduce performance.
D If passengers are talking while you use the speech system,
it may be confused by their speech. You will get better
results if all occupants of the vehicle are quiet while the
system is listening for commands.
<When to speak>
Personal calling — the system is only listening for about 5
seconds after it prompts you to speak. If the system does not
hear a response, it will prompt you again, or cancel the
transaction. If you begin to speak too soon, it will tell you
"Slower, please".
Try pausing for a half second before
speaking.
<How to speak>
D Speak forcefully and clearly. The noisier the environment,
the louder you need to speak. If you are in the driver's seat,

speak facing the front of the vehicle. If you are a passenger,
speak facing the inside rear view mirror.
D Speak calmly and naturally. The system may sometimes fail
to hear your repeated attempts to give a command. If your
speech is distorted by shouting or frustration, this may
cause more errors.
D People with high pitched voices may have better results by
speaking in a deeper, lower pitched voice. However, do not
lower the volume of the voice.
D Avoid speaking with a rising intonation, like asking a
question. Use a flat or falling intonation, like giving an
answer.
