PROBLEM TO BE SOLVED: To provide a received voice output apparatus capable of receiving voice data from a plurality of transmission sources by one receiving terminal and concurrently outputting different voices from a plurality of speakers. SOLUTION: A voice-over-Internet protocol (VoIP) receiving terminal 14 receives a voice packet sent from a transmission source by a network adapter 21 and identifies, in a packet reception processing process 31, which transmission source transmitted a real-time transport protocol (RTP) packet. In a voice CODEC processing process 32, voice data whose transmission source is identified are extended in accordance with a voice compression scheme of each of transmission sources. In a multi-control processing process 33, voice data after the extension processing are selected in accordance with the setting of an operation control and state display processing process 34 and output to a D/A conversion + voice playback processing section 23 together with playback information instructing contents of playback by speakers 15a, 15b. The D/A conversion + voice playback processing section 23 converts the voice data into analog voice signals, performs voice playback processing thereon and outputs them from the speakers 15a, 15b on the basis of the playback information.
