Voice amplification
Overview
The voice amplification function facilitates
communication between the driver and front
passenger with passengers in the rear com-
partment. The signals picked up by the micro-
phone in the rear view mirror are amplified
and played back over the speakers in the rear compartment, depending upon vehicle noise
levels.
An automatic adjustment matching occurs
based on speaker volume and ambient noise.
The optimum distance of the speaker from
the rear view mirror is approximately 50 cm.
When the system is active, the feeling of
space and the natural nature of speech play-
back should be maintained as far as is possi-
ble; speech intelligibility should be improved
when there is an increase in background
noise.
If the volume of a background media source
exceeds a threshold, the speech amplifica-
tion is stopped. The threshold is designed for
relaxed conversation with background music.
If the threshold value is not exceeded, the
voice amplification is continued with a slight
time delay.
Voice amplification is paused during active
telephone calls or when using the Voice Con-
trol System. A message will appear in the dis-
play.
You can assign these functions to the favor-
ites button (
Ypage 56).
