High recognition capability is obtained even with voice input from a user terminal low in power consumption. A user system (1) incorporating a voice instruction recognition processing portion (4) and a transmission control portion (6) is connected to a center system (2) incorporating a reception control portion (7), a voice instruction recognition processing portion (5), and an output control portion (8) through a communication line (3). Processing for obtaining a voice instruction content based on a waveform analysis result of the voice instruction is shared by voice instruction recognition processing portions (4, 5). This prevents decrease of a recognition rate like the case of disposing a voice analysis recognition processing function only on the center system (2) side. Also, there is eliminated waiting time for transfer of lexical grammar data generated in the case of disposing the voice analysis recognition processing function only on the user system (1) side, and a processing load of the user system (1) side is decreased. This makes it possible to accept a voice instruction with a large lexis even if the user system (1) is a mobile device such as cell phones that are low in power consumption.
