What is VOX on a Walkie Talkie?

In any setting where portable radio communications are required, a walkie-talkie is portable handheld two-way radios that will let you communicate wirelessly on a single frequency band using radio waves. This can both send and receive information, unlike any other normal radio, and implies that only one individual can speak at a time.

People are communicating with the use of walkie-talkie to share the same channel or frequency band. They press the push-to-talk button or activate the VOX when someone wants to talk, forcing their loudspeaker to switch to the microphone component to avoid static sound throughout the process.


Short Answer

VOX or Voice Operated Transmission, or more frequently referred to as voice-activated transmission. It allows us to use our radios “hands-free.” When the VOX is activated, it means that when the user starts talking, your radio automatically puts itself on and shuts down if it can’t detect any sound.

This feature on 2-way radios makes it more uncomplicated without asking demand on the effort to press the microphone button when you want to start transmitting. At all times, the microphone listens to your voice and will automatically start broadcasting when the sensor detects users who are speaking.

Long Answer

VOX is a sound-activated, not only voice-activated. This means, for example, if you use your Motorola TLKR 60 in a very loud setting, it can pick up background noises and will be in continuous transmission mode. A lot of handsets on the radio are VOX compatible. Some come with a switch toggle to let you switch between the use of PTT and VOX. Manufacturers use sensitivity setup to help with the activation process to break off unwanted transmissions. The transmission will only kick in when it detects sound beyond a certain decibel level.


Push-To-Talk (PTT)

Two-way radios have a push-to-talk button called the “press to talk”. This will allow you to communicate with a simple push of a button effortlessly over a greater range of distance. The push-to-talk button enhanced performance from your workforce, which provides a clear path to greater productivity and performance by eliminating or significantly reducing things like background noises.

Miscommunication occurs all the time with traditional communication methods. This is not the case with push-to-talk radios, for it provides instant updates and allows for immediate messages received to be verified without less miscommunication. With the push of a button, two-way radios give you options, without dialing, no voice mails, and no delays.



Voice-operated transmission is a switch that works when the sound is detected at a specific range when someone talks, VOX is typically used to turn on a transmitter or microphone and is switched off when they stop talking. VOX is automatic so that users can keep their hands free while speaking. However, VOX also has various drawbacks that are susceptible where it produces unnecessary, unwanted background noise. This explains why PTT is commercially successful.

Push-to-talk is a two-way transmission system that uses a half-duplex system where channeling of data is in one direction that only one party can share information at a time. To use PTT, users have to press the PTT control button while talking, and then release it when done. The listener must do the same thing to respond. In this kind of method, users can also observe the background noise upon transmitting information or communicate. The push-to-talk button requires an effort to press the button upon speaking, but it does observe a polished way to convey a message more efficiently and enable another user to receive a message.


Can you use VOX on every Walkie Talkie?

VOX in every walkie-talkie? Not all walkie-talkie comes with VOX. Many children’s models lack this feature so that radios can be sold at a more budget-friendly price. If you need a walkie-talkie that you can use hands-free, some models are a great radio option for the workplace, where hands-free communication can be essential.


How to use VOX?

To set up a VOX earpiece, make sure that the radio switches off if you’re using the VOX earpiece. Plug the piece into the radio, then switch it back on. The radio will then identify the presence of the accessory VOX microphone, and the icon will show on display. There are 2-way radios, ranging from the least sensitive to the most sensitive. Usually, the lowest sensitivity setting is one that is suitable for noisy areas.

For very quiet places, the highest number reflects the most sensitive amount. The function from the menu is where you will set the VOX sensitivity and select the appropriate degree of sensitivity for your area. Then, to go to that next function, press the press-to-talk key or menu option, and your VOX setting will be activated.


VOX Accessories

If users are Going to be in a noisy setting, earpieces on VOX radios are recommended so that no major transmissions are lost. Earpieces also help to eliminate more background noise, which would allow the microphone to pick up the sound of your voice better than radio tied on to your belt since the earpiece microphone will be closer to your mouth, and that will make hands free communication much efficient and more comfortable.

The walkie-talkie is usually equipped to provide easy access within the specified allocation of the system to all available channels, enabling the communication capability of users to speak in the direction of two-way radio. The VOX was eventually engineered and built with advances in science and technology. Where it finally one of the new fads, like the walkie-talkie in communication devices. VOX has become the modern substitute to the traditional push-to-talk button on the modern editions and makes walkie-talkies, more than anything else, a comfort feature.

VOX on walkie-talkie will immediately begin transmitting by merely talking, VOX mode is triggered and enables the sound-activation technology of the VOX to work its magic. VOX style headsets still hold the microphone active, so when the user talks, the radio will start transmitting automatically. Before each transmission, it frees the user of the burden of having to push a microphone button.


Conclosure – What is VOX on a Walkie Talkie?

There are important things to consider VOX on a walkie-talkie: the distinction between voice-stimulation and sound-stimulation. It is not only the tone of your voice that will activate the VOX but also from somebody’s sound or other background agents that might cause enough noise for VOX to pick up. In a noisy setting, VOX will be in constant “transmit” mode.

VOX on walkie-talkie is modern in place of the standard and traditional push-to-talk button. There are still two-way devices, including walkie-talkie, that feature the conventional push-to-talk button and the one built with VOX. These two-way radios include ways of simplifying, clarifying, and standardizing radio communication.
