PROBLEM TO BE SOLVED: To provide a technique for making the time from when a user inputs a voice till when text data is obtained felt short in a speech recognition system of a client-server model, and for preventing the growth of congestion of a network.SOLUTION: Information indicating a congestion state in a network N is acquired from a network monitoring device 2, and determination is made as to whether or not the acquired information indicating the congestion state indicates that the congestion state is higher than a predetermined congestion state (S1). When determination is No in step S1 and further No in step S3, too, determination is made as to whether or not a length of time of voice stored in a use history database 12 is longer than a predetermined length of time (S5). When determination is Yes in step S1, or Yes in step 5, non-compressed voice data is compressed, and the compressed voice data is transmitted to a voice recognition device 3 (S11). When determination is No in step S5, the non-compressed voice data is transmitted to the voice recognition device 3 directly as it is (S13). |
