Method of using a packet-switched network, a data processing system, a microphone system, and a speaker system

A Voice over Internet Protocol (VoIP) microphone system for use with a packet-switched network, the VoIP microphone system comprising:

• a microphone;
• a content module configured to receive audio content from the microphone;
• an address module configured to identify an address of an intended recipient for a broadcast message including the audio content;
• a broadcast message module configured to receive the audio content from the content module and to associate the address from the address module with the audio content from the content module to form the broadcast message;
• and
• a transmission module configured to send the former broadcast message over the packet-switched network, wherein the broadcast message is communicated as a Voice over Internet Protocol (VoIP) communication.

A Voice over Internet Protocol (VoIP) speaker system for use with a packet-switched network, the VoIP speaker system comprising:

• a receiver module configured to receive a broadcast message that is communicated as a VoIP communication over the packet-switched network, wherein the broadcast message is deliverable via the VoIP connection after an address within the broadcast message has been determined by a user that provided an audio content of the broadcast message;
• a content extraction module configured to extract audio content from the broadcast message;
• and
• an audio module configured to convert the extracted audio content to an audio signal.
