Abstract

An object of the invention is to conveniently increase standard patterns registered in a voice recognition device to efficiently extend the amount of words that can be voice-recognized.

New standard patterns are generated by modifying a part of an existing standard pattern. A pattern matching unit 16 of a modifying-part specifying unit 14 performs pattern matching process to specify a part to be modified in the existing standard pattern of a usage source. A standard pattern generating unit 18 generates the new standard patterns by cutting or deleting voice data of the modifying part of the usage-source standard pattern, substituting the voice data of the modifying part of the usage-source standard pattern for another voice data, or combining the voice data of the modifying part of the usage-source standard pattern with another voice data. A standard pattern database update unit 20 adds the new standard patterns to a standard pattern database 24.

Claims

1-13. -13. (canceled)

14. A voice edition apparatus that uses existing voice data to generate another voice data, comprising:

a modifying-part specifying unit that performs a matching process between usage-source voice data among the existing voice data and modifying-part voice data for specifying a modifying part of the usage-source voice data, and specifies at least a part of the usage-source voice data as the modifying part; and

a voice data generating unit that uses the modifying-part voice data specified by the modifying-part specifying unit to generate another voice data.

15. The voice edition apparatus of claim 14, wherein the voice data generating unit generates, as another voice data, voice data obtained by substituting the modifying-part voice data of the usage-source voice data specified by the modifying-part specifying unit with different voice data.

16. The voice edition apparatus of claim 14, wherein the voice data generating unit generates, as another voice data, voice data obtained by combining the modifying-part voice data specified by the modifying-part specifying unit with different voice data.

17. The voice edition apparatus of claim 15, wherein the different voice data used to generate another voice data comprises voice data that is input to the voice edition apparatus from the outside, voice data that is cut from the existing voice data, or the existing voice data.

21. A voice edition method that uses existing voice data to generate another voice data, the method comprising:

performing a match process between usage-source voice data and modifying-part voice data for specifying a modifying part of the usage-source voice data and specifying at least a part of the usage-source voice data as the modifying part, and

using the specified modifying-part voice data to generate another voice data.

23. A voice edition program product embodied on a computer readable medium which, when executed by a computer, cause the computer to execute the voice edition method of claim 21.

22. A voice recognition method that uses an existing standard pattern to generate another standard pattern, the method comprising:

performing a matching process between a usage-source standard pattern and modifying-part voice data for specifying a modifying part of the usage-source standard pattern and specifying at least a part of the usage-source standard pattern as the modifying part; and

using the specified modifying-part voice data to generate another standard pattern.

24. A voice edition program product embodied on a computer readable medium which, when executed by a computer, cause the computer to execute the voice edition method of claim 22.
