Abstract: An acoustic system comprises an output unit, a communication unit, a first output control unit, and a second output control unit. The output unit is configured to be capable of outputting a sound and an image. The communication unit is configured to be capable of communicating with an external device. The first output control unit is configured to receive, from a communication device that transmits a reproduction signal for acoustic data, the reproduction signal via the communication unit and to cause the output unit to output a sound based on the reproduction signal, to thereby perform reproduction of a series of sounds represented by the acoustic data. The second output control unit is configured to cause the output unit to output, as the image, a word corresponding to the sound outputted by the output unit among the series of sounds represented by the acoustic data.
