Abstract

A speech processing device includes: a dialog execution control unit that controls speech output and timings of speech recognition in accordance with dialog information including speech output information, speech recognition information and control information; a speech output control unit that outputs an output speech signal designated by the speech output information; and a speech recognition unit that executes speech recognition processing for an input speech signal using the speech recognition information. The control information includes speech output timing information for the output speech signal and speech recognition start timing information for the input speech signal. The speech recognition start timing information is specified by a time period that elapses from a first timing specified by the speech output timing information.

Claims

1. A speech processing device comprising:

a dialog execution control unit that controls speech output and timings of speech recognition in accordance with dialog information including speech output information, speech recognition information and control information;

a speech output control unit that outputs an output speech signal designated by the speech output information under control of the dialog execution control unit; and

a speech recognition unit that executes speech recognition processing for an input speech signal using the speech recognition information under control of the dialog execution control unit, wherein

the control information includes speech output timing information for the output speech signal and speech recognition start timing information for the input speech signal, and

the speech recognition start timing information is specified by a time period that elapses from a first timing specified by the speech output timing information.

2. The speech processing device according to claim 1, wherein

the dialog information includes two or more pieces of the speech output information, and the speech output timing information that specifies output of a predetermined one of the pieces of speech output information is specified by a time period that elapses from completion of output control for one of the pieces of speech output information that is output immediately before an output of the predetermined piece of speech output information.

3. The speech processing device according to claim 1, further comprising

a dialog storage unit that stores the dialog information.

4. The speech processing device according to claim 1, wherein

the first timing is specified by the speech output timing information corresponding to a piece of speech output information that is output last out of pieces of the speech output information included in the dialog information.

5. An integrated circuit device comprising the speech processing device according to claim 1.

6. An integrated circuit device comprising the speech processing device according to claim 2.

7. An integrated circuit device comprising the speech processing device according to claim 3.

8. An integrated circuit device comprising the speech processing device according to claim 4.

9. A speech processing system comprising:

a speech processing device;

a speech input unit;

an information display unit; and

a speech output unit, wherein

the speech processing device includes;

a dialog execution control unit that controls speech output and timings of speech recognition in accordance with dialog information including speech output information, speech recognition information and control information;

a speech output control unit that controls the speech output unit, and outputs an output speech signal designated by the speech output information under control of the dialog execution control unit; and

a speech recognition unit that executes speech recognition processing for an input speech signal output from the speech input unit using the speech recognition information under control of the dialog execution control unit,

the control information includes speech output timing information for the output speech signal, speech recognition start timing information for the input speech signal, and display start timing information for the information display unit, and

the speech recognition start timing information and the display start timing information are specified by a time period that elapses from a first timing specified by the speech output timing information.

10. The speech processing system according to claim 9, wherein

the first timing is specified by the speech output timing information corresponding to a piece of speech output information that is output last out of pieces of the speech output information included in the dialog information.

11. A control method for a speech processing device, comprising

establishing dialog information that includes speech output information, speech recognition information and control information, the control information including speech output timing information and speech recognition start timing information;

outputting the speech output information in accordance with the speech output timing information; and

executing speech recognition processing using the speech recognition information in accordance with the speech recognition start timing information, wherein

the speech recognition start timing information is specified by a time period that elapses from a first timing specified by the speech output timing information.

12. The control method for the speech processing device according to claim 11, further comprising

executing display processing using display information in accordance with display start timing information, the display information being included in the dialog information, and the display start timing information being included in the control information, wherein

the display start timing information is specified by a time period that elapses from the first timing.
