11 best voice activated radios

Voice-activated radios, also known as VOX (Voice Operated Transmit) radios, are a type of two-way radio system that allows users to communicate hands-free. These radios are commonly used in various applications, including CB (Citizens Band) radios, portable audio and video devices, and electronics such as baby monitors and intercom systems. Here's some information about voice-activated radios and their applications:

  1. Two-Way Radios:

    • Voice-activated radios are often used in two-way radio communication systems, such as walkie-talkies and professional radio systems used by first responders and security personnel.
    • The VOX feature eliminates the need to press a push-to-talk (PTT) button to transmit a message. Instead, the radio detects the user's voice and automatically activates transmission when speech is detected.
  2. CB Two-Way Radios:

    • Citizens Band (CB) radios are a popular application for voice-activated radios. They are commonly used by truckers, travelers, and hobbyists for communication on designated CB channels.
    • VOX functionality in CB radios allows drivers to communicate without taking their hands off the wheel, enhancing safety while on the road.
  3. Portable Audio and Video Devices:

    • Voice-activated radios are integrated into some portable audio and video devices, such as baby monitors and hands-free communication systems.
    • In baby monitors, VOX helps parents monitor their baby's sounds and cries without the constant need to manually activate the audio feed.
  4. Electronics:

    • VOX technology can be found in various electronic devices like intercom systems and security cameras.
    • In intercom systems, VOX enables hands-free communication between different rooms or areas in a building or home.
  5. How VOX Works:

    • Voice-activated radios use a sensitive microphone to detect audio input. When the microphone detects sound above a certain threshold (usually the user's voice), the radio automatically switches to transmit mode.
    • After the user stops speaking, there is typically a brief delay before the radio returns to receive mode.
    • Users can often adjust sensitivity settings to fine-tune the VOX feature according to their preferences and environment.
  6. Advantages:

    • Hands-free operation is one of the main advantages of voice-activated radios, making them useful in situations where manual PTT operation may not be practical.
    • VOX technology can improve convenience and safety in various applications, allowing users to communicate without interruptions.

Voice-activated radios are versatile devices with applications ranging from recreational use in CB radios to critical communication systems in public safety. They offer a hands-free communication solution that can be valuable in many situations.
