This event is sent to all clients when the Listening mode begins after the user presses the Listening key or when its time-out ends, or when the input-active client calls the IAgentCharacterEx::Listen method with True or False.

The event returns values to the clients that currently have this character loaded. All other clients receive a null character (empty string).
