Voice-operated exchange, often shortened to VOX, refers to a feature found on some two-way radios (walkie-talkies) that enables hands-free operation. When activated, the radio automatically transmits when the user speaks into the microphone, eliminating the need to press the push-to-talk (PTT) button. For instance, a security guard patrolling a site can communicate updates without interrupting their activities, such as opening doors or carrying equipment.
The implementation of this capability offers significant advantages in situations where manual operation is difficult or impractical. Benefits include improved safety, increased efficiency, and enhanced user comfort, particularly in professions or hobbies requiring continuous communication. The origin of hands-free communication stems from the need for uninterrupted operation in scenarios demanding focus and dexterity, such as aviation and emergency response.
