Using VOX mode on Android
VOX mode allows you to activate Zello with your voice in order to trigger a transmission. This feature allows you to use Zello hands-free.
Users must have Zello version 3.106 or newer to use this feature. VOX is also available on our PC app: Using VOX mode on a PC
To turn on VOX mode:
✔️Go to the Zello app menu>Options>Push-to-talk buttons. Select VOX Button
✔️Turn on "Show button on the talk screen"
✔️Return to the talk screen and tap on the voice transmission icon to turn VOX ON. The button will turn blue. You can toggle this button on or off to go from push-to-talk mode and VOX mode.
Important: To avoid unintended transmissions VOX automatically suspends when the screen is turned off or user navigates away from the talk screen.
Please note that VOX mode can be configured and fine-tuned so that transmissions are triggered with the correct noise level.
To fine-tune, you can adjust the following:
- Activation sensitivity: Allows you to set the sensitivity level (Low, Moderate, High, Extreme) to activate transmissions. Low would allow faint noises to trigger a transmission, while Extreme would only allow very loud noises to trigger a transmission.
- Tailor activation to the human voice: Allows you to set the sensitivity level (Low, Moderate, High, Extreme) to activate an algorithm that looks to filter out other noises (a mouse click, wind, etc) from the human voice.
- Activation time (ms): Allows you to set the amount of time that must elapse in order for VOX to begin sending a message.
- Deactivation time (ms): Allows you to set the amount of time that must elapse at the end of a message to end VOX.
