摘要： A speech communication device includes a data receiver that receives data from other device. The received data is stored in a buffer. The amount of the data in the buffer is monitored at a predetermined timing. When the amount of data in the buffer exceeds a steady delay threshold, an action determining unit instructs reduction in the stored data, reduction of an initial storage amount, and reduction of an upper limit threshold (a substantial buffer capacity).
