Related to Telephone
The system should respond correctly to all voice comm ands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each soluti on in turn, starting with number 1, until the problem is
resolved.
Symptom Possible cause Possible solution
The system does not
recognize your com-
mand.
or
The system recognizes
your command incor-
rectly The interior of the vehicle is too noisy. Close the windows or have other occupants quiet.
The volume of your voice is too low. Speak louder.
The volume if your voice is too loud. Speak softer.
Your pronunciation is unclear. Speak clearly.
You are speaking before the voice recognition is ready
Press and release “ ” switch on the steering
switch, and speak a command after the tone
sounds.
8 seconds or more have passed after you pressed and
released “ ” switch on the steering switch. Make sure to speak a command within 8 seconds
after you press and release “ ” switch on the
steering switch.
Only a limited range of voice commands is usable for
each screen. Use a correct voice command appropriate for the
current screen.
The fan of the air conditioner is too loud. Lower the fan speed as necessary as voice com-
mand can be recognized more easily.
Symptom/ error message Solution
Displays “CO MMAND NOT REC-
OGNIZED” or the system fails to in-
terpret the comm and correctly. 1. Ensure that the command format is valid.
2. Speak clearly without pausing between words and at a level appropriate to the ambient noise
level.
3. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.
NOTE:
If it is too noisy to use the phone, it is li
kely that voice commands will not be recognized.
4. If optional words of the command have been omitted, then command should be tried with these
in place.
The system consistently selects
the wrong voicetag 1. Ensure that the voicetag requested matches what was originally stored. This can be confirmed
by giving the “Addressbook” Directory or Phone Directory command.
2. Replace one of the voicetags being confused with a different voicetag.
Symptom Solution
System fails to interpret the com-
mand correctly. 1. Ensure that the command is valid.
2. Ensure that the command is spoken after the tone.
3. Speak clearly without pausing between words and at level appropriate to the ambient noise lev-
el in the vehicle.
4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster
on).
NOTE:
If it is too noisy to use the phone, it is likely
that the voice commands will not be recognized.
5. If more than one command was said at a time, try saying the commands separately.
6. If the system consistently fails to recognize commands, the voice training procedure should be
carried out to improve the recognition response for the speaker. See “Speaker adaptation (SA)
mode” earlier in this section. Refer to “OWNER’S MANUAL”.
