PROBLEM TO BE SOLVED: To allow operation to change voice such as sound quality change operation and content change operation to be performed from a speaker apparatus side in a voice radio transmission system in which a source apparatus transmits a voice signal to a plurality of speaker apparatuses by radio communication.SOLUTION: In a system of the present invention, a speaker apparatus 2 accepts user operation, and outputs a voice signal changed according to an operation signal indicated by the user operation. Here, the speaker apparatus 2 transmits the operation signal to a source apparatus 1, and the source apparatus 1 changes a voice signal or voice signal processing parameter to output to a plurality of speaker apparatuses 2 on the basis of the received operation signal. Alternatively, the speaker apparatus 2 applies signal processing to the voice signal received from the source apparatus 1 with a voice signal processing parameter indicated by the operation signal and transmits an execution notice of the signal processing to the source apparatus 1.SELECTED DRAWING: Figure 1 |
