Abstract
An apparatus for positively recognizing speech generated by a large, unspecified number of speakers performs optimal speech recognition processing on the basis of speech information dictionaries corresponding to the respective speakers by consecutively inputting and preparing in advance speech information dictionaries corresponding to the respective speakers.
Claims14
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.

A speech information processing apparatus comprising:
- storage means for receiving and storing prerecorded speech information to be used in recognizing input speech information;
- speech recognition means for receiving the input speech information and effecting speech recognition of the input speech information according to the prerecorded speech information stored in said storage means;
- changeover means for changing over the connection of a public line from being connected to said storage means to being connected to said speech recognition means;
- and
- controlling means for controlling said changeover means to connect the public line to said storage means when prerecorded speech information is received, said controlling means controlling said storage means to store the received prerecorded speech information, said control means confirming the form of the received prerecorded speech information, said controlling means transmitting an error signal through the public line when detecting an abnormality in the received prerecorded speech information, said controlling means repeatedly performing the storing, confirming, and transmitting operations when an abnormality is detected, said controlling means transmitting a signal confirming the completion of receipt of the prerecorded speech information when an abnormality is not detected, and said controlling means controlling said changeover means to connect the public line to said speech recognition means when said controlling means transmits the confirming signal.

A method of processing speech information comprising:
- receiving input speech information in speech input receiving means;
- reading from a recording medium prerecorded speech information and controlling the reading with control means;
- connecting a public line to the control means;
- transmitting the read out prerecorded speech information through a public line to a speech recognition device;
- detecting a communication error in the communication of the prerecorded speech information to the speech recognition device through the public line;
- repeating the transmitting of the read out prerecorded speech information through the public line to the speech recognition device when detecting a communication error in said detecting step while maintaining the connection to the public line;
- confirming the proper completion of transmission of the prerecorded speech information when the proper transmission of the prerecorded speech information is completed;
- changing over the connection of a public line from being connected to the control means to being connected to the speech input receiving means;
- controlling said changing over step so that the public line is connected to the control means when the prerecorded speech information is to be transmitted to the public line and so that the public line is connected to the speech input receiving means after said confirming step by receiving a signal confirming completion of transmission of the prerecorded speech information;
- and
- transmitting the input speech information to a speech recognition device through the public line when the public line is connected to the speech input receiving means.

A method of processing speech information comprising:
- receiving and storing prerecorded speech information to be used in recognizing input speech information in storage means;
- receiving the input speech information and effecting speech recognition of the input speech information according to the prerecorded speech information stored in the storage means with speech recognition means;
- changing over the connection of a public line from being connected to the storage means to being connected to the speech recognition means with changeover means;
- and
- controlling the changeover means to connect the public line to the storage means when prerecorded speech information is received;
- confirming the form of the received prerecorded speech information;
- transmitting an error signal through the public line when said confirming step detects an abnormality in the received prerecorded speech information;
- repeatedly performing said receiving and storing, confirming, and transmitting steps when said confirming step detects an abnormality in the received prerecorded speech information;
- transmitting a signal confirming the completion of receipt of the prerecorded speech information with control means when an abnormality is not detected in said confirming step;
- and
- controlling the changeover means to connect the public line to the speech recognition means when the control means transmits the confirming signal.
