Push-to-talk

Push-to-talk (PTT) allows users to initiate voice transmission by pressing a designated button or key, instead of continuously broadcasting audio.

The user is required to activate the microphone only when they want to speak, mimicking the functionality of a walkie-talkie or two-way radio. This approach helps reduce background noise and conserve bandwidth, making it particularly useful in situations where multiple users share a communication channel. Push-to-talk is commonly employed in various contexts, including professional settings, online gaming, and mobile applications, enabling efficient and controlled voice communication among individuals or groups.
