The Push-to-talk (PTT) Market is a two-way communication method that allows users to transmit audio only when a button is pressed. It is commonly used in radio communication systems, such as walkie-talkies and two-way radios, where it is impractical to have an open microphone all the time. In PTT systems, the user presses a button to activate the microphone and transmit their message to the other party or parties. When the button is released, the microphone is turned off, and the user can receive messages from the other party or parties.
