  • VOX, or voice-activated transmission, means that the walkie talkie only begins transmitting once you start talking
  • This makes it hands free!
  • It’s different than Push To Talk (PTT), because obviously that only works when you push a button
  • Many walkie talkies have both features so you can switch between them as needed

What is voice-activated transmission (VOX)

VOX, also known as “voice-operated exchange,” or “voice-activated transmission” is a capability that only begins transmitting once you begin speaking, meaning that it’s hands-free to use. Unlike Push To Talk (PTT), the VOX microphone is ready to transmit whenever it detects speech over a certain frequency threshold and ceases when you finish talking.

This allows for hands-free operation of your two-way radio, which can be very useful in situations where you need to be able to communicate without using your hands.

VOX vs PTT

VOX is a great feature for those who need to be able to communicate without using their hands, but it’s not the only option available. PTT, or Push To Talk, is another way to operate your two-way radio. With PTT, you press and hold a button on your radio to transmit your voice.

PTT is a more traditional way of operating a two-way radio and doesn’t require any special features or equipment. It’s also the more common way of operating two-way radios, so you may be more familiar with it.

If you’re not sure which method is right for you, multiple walkie talkies offer both VOX and PTT so you can try both and see which one you prefer.
