push-to-talk
Press to broadcast
Push-to-talk is a communication system where you press and hold a button to transmit, then release to listen—like a walkie-talkie.
The design prevents simultaneous transmission, keeping channels clear.
Modern push-to-talk apps replicate this on smartphones: Hit the push-to-talk button when you're ready to speak.
Often abbreviated PTT.
