PROBLEM TO BE SOLVED: To provide a wireless voice transmission system and source equipment for quickly forming the optimal acoustic field even when a listener moves.SOLUTION: A wireless voice transmission system includes: a plurality of speaker equipment 2; source equipment 1 for transmitting a voice signal to each speaker equipment through wireless communication; and terminal equipment 3. Each speaker equipment is able to receive a wireless signal from the terminal equipment, and transmits information on wireless communication between the terminal equipment and its own speaker equipment to the source equipment. The source equipment includes: a position estimation part 10a for estimating the position of terminal equipment from the information on the wireless communication; a signal processing part 14 for determining a voice signal or a voice signal processing parameter to be output to each speaker equipment in accordance with a distance between the terminal equipment whose position is estimated by the position estimation part and each speaker equipment; and a signal transmission part 15 for transmitting the determined voice signal or voice signal processing parameter to each speaker equipment.SELECTED DRAWING: Figure 1 |
