What Is Vox On Walkie Talkie?

What is Vox on walkie talkie? The term VOX in telecommunications stands for voice-operated exchange. It is a switch or electronic sound sensor which picks up sounds when a person speaks into a walkie-talkie and then turns on its transmitter, which it uses to transmit this sound into voice data for the receiving end of the communication exchange.

It works as an automatic switch that goes on once a person starts talking, and goes off when the speaking stops. VOX analyses differences in air pressure and converts sound data into electronic signals.

History of Two-way Radio Walkie-Talkie Devices

The earliest designs of the walkie-talkie radio devices had the basic push-to-talk button, which served as both a transmitter and a receiver where a person had to press down on the button to speak into the microphone at the bottom of the walkie-talkie before it is transmitted into radio signals that are received at the other end.

Conversely, when the person releases the button, the transmitter gets turned off, and automatically, the walkie-talkie then serves as a receiver to the other end of the telecommunication exchange.

Essentially, the old walkie-talkies acted as a one-way only street for transmitting and receiving voice signal. Still, technological advancements brought about the VOX, which is the modern trade-off to the push-to-talk button. You don’t have to push down to talk into the walkie-talkie or release to listen with VOX.

VOX is a two-way device where the the two ends of a communication exchange can transmit and receive at the same time.

Examples of Two-Way Radio Devices With VOX Functionalities

VOX is a common feature in most top-of-the-range radio devices. This functionality is clearly stated on the body of most popular devices to affirm their worthiness. Listed below are a couple of high-quality two-way radio devices that come with VOX functions.

  • Motorola T40
  • Motorola TLKR T60
  • Motorola T92 H20
  • BaoFeng UV-3R
  • Axis M10 series
  • Wouxun KG-805G GMRS Two Way Radio
  • Cobra CXY805 FRS Two Way Radios
  • Midland T295VP4 High Powered GMRS Two Way Radios
  • Uniden SX167-2CH FRS Two Way Radios

Many great features put the VOX far ahead of the traditional two-way radio devices. In an analysis, we find the three discussed below to be the most appealing of them and stand out the most. Modern-day radio handsets come with VOX features as;

  • A Complete Hands-Free Option
  • A Noise And Voice Detection Functionality
  • Short Delay Option
  • Storage Capabilities

Complete Hands-Free Option

Most traditional two-way radio typically has a push-to-talk button. But with a VOX, your radio can be used as a hand-free device since the VOX is permanently switched and constantly roaming to pick up any sound or voice. Once it detects your voice, it starts transmitting automatically and turns itself off when it can no longer pick up sounds. This functionality frees users from the usual hassle of pushing down on the button to start talking.

A Noise And Voice Detection Functionality

VOX is built not only as a voice detection device but is also sound activated. This means that if you are using your two-way device in a noisy environment, the VOX will be able to pick up both the noise and your voice since it is always in a transmitting mode. 

While this is a great feature, it could also pose problems, especially when unwanted noise starts getting transmitted over it. To handle this, many radio manufacturing companies include radio settings that allow a user to filter voice from noise and only start transmitting when it can detect a clean sound over a particular decibel level.

Alternatively, many modern radio handsets come with a toggle button that allows you to switch between the push to talk and VOX functionalities.

Short Delay Option

Another great feature of the VOX is its ability to delay in between communication. Traditionally, a user had to push down on a button to talk and then release to listen. Where voice is no longer detected, communication is automatically broken off.

However, with VOX, the communication circuit allows a brief delay in between transmission that accommodates a situation probably where user both users need to pause communication. This way, the circuit remains activated, remains activated, and the communication process is still maintained until both parties decide to end it.

Storage Capabilities

Another interesting functionality of the voice-operated exchange (VOX) is saving storage spaces when used on a recording device. In cell phones, too, VOX devices are great for saving and extending cell phone batteries’ lives.

How To Get Your VOX Activated Device Running

If you own a VOX activated device, ensure that the radio is switched off before inserting it into your handheld radio and then switching it back on. The radio device can automatically pick up new VOX device changesVOX device changesVOX device changes and immediately reports with an icon display to admit receipt.

Conclusion- What is vox on walkie talkie

A lot of two-way radio devices come with different sensitivity levels for the VOX. These sensitivity levels can go from really low to, in most cases, very high. The least of the sensitivity chain is typically the one that is most suitable for noisy environments. At the same time, the highest-end is typically most suited for very calm and noiseless environments.

To toggle the VOX sensitivity on your handset, locate the function from the menu list and then pick from the list of available options the most appropriate or the option that best suits your location’s sensitivity level.

After you must have done this, press down the PTT (push to talk button) or the home menu to proceed to the available commands to get your VOX activated and up and running.
