PROBLEM TO BE SOLVED: To adjust the time of day of a plurality of voice data without using a device capable of acquiring a reference time of day.SOLUTION: A time difference calculation unit 206 calculates a difference in time of day between the local terminal and another terminal on the basis of a time of day at which output of a voice began at the local terminal, a time of day at which input, to the local terminal, of a voice corresponding to voice data that matches first voice data recorded in a recording unit 214 began, a time of day at which input of the voice outputted from the local terminal began at the other terminal, and a time of day at which output of a voice outputted from the other terminal and inputted to the local terminal began at the other terminal. A data synthesizing unit 213 adjusts, on the basis of the calculated difference in time of day, a difference in time of day between second voice data based on the voice outputted from a voice source and inputted to the other terminal and third voice data based on the voice outputted from the voice source and inputted to the local terminal, and then synthesizes the second voice data and the third voice data. |
