When using the microphone
■
It is unnecessary to speak directly into the microphone when giving a command.
●
Wait for the confirmation beep before speaking a command.
●
Voice commands may not be recognized if:
●
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while voice commands are spoken.
• The air conditioning speed is set high.
• The air conditioning vents are turned towards the microphone.
In the following conditions, the system may not recognize the command properly
●
and using voice commands may not be possible:
• The command is incorrect or unclear. Note that certain words, accents or
speech patterns may be difficult for the system to recognize.
• There is excessive background noise, such as wind noise.
When searching for a track
■
A USB memory or iPod must be connected to enable track searching and play-
●
back. ( P. 456, 466)
When a USB memory or iPod is connected, recognition data is created so tracks
●
can be searched using voice commands.
Recognition data is updated under the following conditions:
●
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. ( P. 320)
While the recognition data is being created or being updated, a track search can-
●
not be performed using a voice command.
While "Play Music" is displayed in the "Shortcut Menu" screen, say "Play Music" to
●
display the music screen from which searching for a track using a voice command
can be performed.
When "Play Music" is dimmed in the "Shortcut Menu" screen, it is not possible to
●
search for a track using a voice command. In this situation, reduce the amount of
music data in the USB memory or iPod and update the recognition data to enable
searching by voice command.
