A sound field control system SY according to the present invention is provided with: a sound emission unit 210 which causes a plurality of speakers to emit a test sound; a sound pickup unit 130 which picks up the test sound using a microphone; an analysis unit 150 which compares information indicating a sound emission timing of a test signal sequence for causing the speakers to successively emit the test sound at a prescribed timing with a sound pickup timing of each test sound that has been picked up, and which calculates a time difference between the sound emission timing of each test sound and the sound pickup timing; and a signal processing unit 230 which performs, based on the calculated time difference between the sound emission timing of each test sound and the sound pickup timing, a delay process for a voice signal supplied to each speaker.
