VOX stands for "voice-operated exchanged", and is sometimes also referred to as "voice activated transmission". With VOX switched on, the microphone is always listening out for your voice. When it detects you are speaking, it will then automatically start broadcasting.

What is VOX on a baby monitor?

The Voice Activated Alert (VOX) feature allows you to conserve power on the video monitor. For example, you may want your video monitor to shut off when your baby is sleeping, and turn on when your baby cries. Adjusting the VOX sensitivity levels determines how sensitive the camera is to your baby's cry.

What does VOX do on a walkie talkie?

VOX, also known as “voice-activated transmission” or “voice-operated exchange,” is a switch that begins transmitting when you start talking, making it hands-free. Unlike the PTT, the VOX microphone is ready to transmit whenever it detects noise over a certain frequency threshold and stops when you finish talking.
