A push-to-talk feature on a mobile handset is initiated by speaking a recipient's name as the first part of an initial message. A speech recognition device located in the handset or in a push-to-talk server may recognize the recipient's name, determine the proper addressing for the message, establish a push-to-talk session, and deliver the message to the intended recipient. The session may continue until a session timeout has occurred, until another session is started, or until the user otherwise terminates the session.
