3. A speech information processing apparatus according to claim 1, wherein said control means receives a signal confirming the reception of information of said transmitted speech information, and, if the signal indicates a transmission error, said control means controls said transmission means to retransmit the speech information to the public line.
1. A speech information processing apparatus comprising: speech input receiving means for receiving input speech information; reading means for reading from a recording medium prerecorded speech information for use in recognizing said input speech information; speech information transmission means for transmitting both the input speech information, received by said speech input receiving means, and the prerecorded speech information, read by said reading means, to a speech recognition device through a public line; control means for controlling said reading means to read out the prerecorded speech information, and controlling said speech information transmission means to transmit the read out prerecorded speech information to the speech recognition device through the public line, said control means detecting a communication error in the communication of the prerecorded speech information to the speech recognition device through the public line and controlling said speech information transmission means to repeatedly transmit the read out prerecorded speech information when the communication error is detected while maintaining the connection to the public line, said control means confirming the proper completion of transmission of the prerecorded speech information when said speech information transmission means properly completes transmission of the prerecorded speech information; changeover means for changing over the connection of a public line from being connected to said control means to being connected to said speech input receiving means, wherein said control means controls said changeover means so that the public line is connected to said control means when said control means determines that the prerecorded speech information is to be transmitted to the public line and when the prerecorded speech information is repeatedly transmitted over the public line and wherein the public line is connected to said speech input receiving means after said speech information transmission means transmits the read out prerecorded speech information and said control confirms proper transmission of the prerecorded speech information.
