Abstract: An apparatus (200) for providing a multi-party speech connection for use in a wireless communication system (10). The apparatus (200) comprises a first speech encoder (202) producing a first encoded speech signal, a second speech encoder (20) producing a second encoded speech signal, a conference circuit (22), and a speech decoder (208) responsive to the conference circuit (22). The conference circuit (22) receives the first and second speech encoded signals and produces a multiplexed encoded speech signal. The speech decoder (208) receives the multiplexed encoded speech signal and produces a decoded speech signal.
