When it is determined that sound data is unrecognizable through a speech recognition process by a first speech recognition unit (3), the same sound data as the sound data inputted to the first speech recognition unit (3) is transmitted to a second server device (60) and a first server device (70). Recognition data is generated which is formed of a character string that is a speech recognition result by the second server device (60) with respect to the sound data, and an acoustic model identifier series generated by a first acoustic model identifier series generation unit (27) of the first server (70) based on the sound data, and the generated recognition data is registered in a first recognition dictionary (3b) of the first speech recognition unit (3). |
