Voice Detection

Voice Activation (VOX)
In VOX mode, the microphone activates automatically once a participant speaks. The mode is ideal for meetings that are more
conversational, allowing back-and-forth communication that doesn't involve speak requests and button activation. The following
settings allow VOX to be customized for the meeting:
Voice Detection Threshold
Release Time
Book Drop
Last Mic Stays Open
Determines the input level (dB) that activates the microphone. Lower settings activate the
microphone with a quieter source, while higher settings require a louder source to activate
the microphone.
Default 0 dB
Minimum -12 dB
Maximum 8 dB
Determines how long a microphone remains active after a participant stops talking. The set-
ting is selectable in 0.5 second increments.
Default 4 seconds
Minimum 1 seconds
Maximum 10 seconds
To ensure that only the speech from a participant activates the microphone, turn on the book
drop feature. This quickly turns off a microphone that has been accidentally activated from a
loud noise other than speech.
This setting ensures that at least one microphone is always activated. This is useful for video
or audio conferences with echo-canceling equipment.
