6.17 Enabling and Disabling Voice Activation
The voice activation function is used during ongoing discussions in the conference. The site with
the loudest voice is viewed by the other sites in the conference.
You can select the sensitivity based on experience after enabling the voice activation function.
l
The videoconferencing system sets a threshold based on the sensitivity selected. If the
volume of one or multiple sites exceeds the threshold, the video of the site with the highest
volume is broadcast.
l
If no site exceeds the threshold, the conference status remains unchanged.
If a conference is held using cascaded built-in MCUs and voice activation is enabled on the
master MCU, voice activation is enabled automatically on slave MCUs. For details about master
and slave built-in MCUs, see section
Initiating a Conference by Cascading Built-In MCUs
To disable voice activation, select
Disable
from the
Voice Activation
drop-down list box.
