What is vox on a walkie talkie?

VOX (Voice Operated Exchange) is a feature in a walkie talkie that allows the user to communicate hands-free. When VOX is enabled, the walkie talkie will automatically detect when the user is speaking and transmit their voice without the need to press a push-to-talk button. This can be useful in situations where the user needs to communicate while performing other tasks that require the use of their hands.

VOX sensitivity levels can usually be adjusted to accommodate different speaking volumes, and some walkie talkies also have a VOX delay feature that allows the user to set a delay before the transmission begins after speaking.

Overall, VOX can be a convenient feature for users who need to communicate hands-free while using a walkie talkie.
