Abstract

Textual transcription of speech is generated and formatted according to user-specified transformation and behavior requirements for a speech recognition system having input grammars and transformations. An apparatus may include a speech recognition platform configured to receive a user-specified transformation requirement, recognize speech in speech data into recognized speech according to a set of recognition grammars; and apply transformations to the recognized speech according to the user-specified transformation requirement. The apparatus may further be configured to receive a user-specified behavior requirement and transform the recognized speech according to the behavior requirement. Other embodiments are described and claimed.

Claims

1. A computer-implemented method comprising:

receiving a user-specified behavior requirement in a speech recognition system;

receiving a request to recognize speech from an application;

recognizing the speech to form a recognized word sequence;

transforming the recognized word sequence according to the user-specified behavior requirement; and

providing the transformed sequence to the application.

2. The method of claim 1, comprising:

receiving a user-specified transformation requirement in the speech recognition system; and

transforming the recognized word sequence according to at least one of the user-specified behavior requirement or the user-specified transformation requirement.

3. The method of claim 2, wherein at least one of the user-specified behavior requirement or the user-specified transformation requirement includes a semantic tag, and wherein transforming the recognized word sequence comprises:

determining which transformations to apply to a sub-segment of the recognized word sequence according to a semantic tag associated with the sub-segment.

4. The method of claim 3, wherein the semantic tag specifies at least one of:

a proper name, a phone number, an address, a date, a time, an email address, an internet protocol address, or a web address.

5. The method of claim 1 wherein the user-specified behavior requirement comprises at least one of:

a grammar, an application program interface (API) call, an extensible markup language (XML) element, an XML schema, or speech recognition application parameters.

6. The method of claim 1, wherein the user-specified behavior requirement changes a setting of an input grammar regarding a built-in transformation.

7. The method of claim 6, comprising at least one of:

selecting a transformation from a set of built-in transformations;

or

de-selecting a transformation in a set of built-in transformations.

8. The method of claim 1, wherein the user-specified behavior requirement specifies a first transformation for a first portion of an input grammar, and a second transformation for a second portion of the input grammar.

9. A system for implementing formatted recognized speech, the system comprising:

a speech recognition platform configured to;

receive a user-specified transformation requirement;

recognize speech in speech data into recognized speech according to a set of recognition grammars; and

apply transformations to the recognized speech according to the user-specified transformation requirement.

10. The system of claim 9, further comprising:

a client application configured to;

create a user-specified transformation requirement;

request speech recognition using the user-specified transformation requirement from the speech recognition platform.

11. The system of claim 9, the speech recognition platform further configured to:

receive a user-specified behavior requirement; and

transform the recognized word sequence according to the user-specified behavior requirement.

12. The system of claim 11, wherein at least one of the user-specified transformation requirement or the user-specified behavior requirement comprises at least one of:

a grammar, an application program interface (API) call, an extensible markup language (XML) element, an XML schema, or speech recognition application parameters.

13. The system of claim 11, the speech recognition platform further configured to:

determine which transformations to apply to a sub-segment of the recognized speech according to a semantic tag associated with the sub-segment.

14. The system of claim 9, wherein the speech recognition platform comprises an input grammar and a built-in transformation, and wherein the user-specified behavior requirement changes a setting of an input grammar regarding the built-in transformation.

15. The system of claim 14, the speech recognition platform configured to at least one of:

select a built-in transformation according to the user-specified behavior requirement;

or

de-select a built-in transformation according to the user-specified behavior requirement.

16. The system of claim 14, wherein the user-specified behavior requirement specifies a first transformation for a first portion of the input grammar, and a second transformation for a second portion of the input grammar.

17. An article comprising a storage medium containing instructions that if executed enable a system to:

receive a request to recognize speech from an application;

recognize the speech to form a recognized word sequence;

transform the recognized word sequence according to a user-specified behavior requirement; and

provide the transformed sequence to the application.

18. The article of claim 17, further comprising instructions that if executed enable the system to transform the recognized word sequence according to at least one of the user-specified behavior requirement or a user-specified transformation requirement.

19. The article of claim 17, wherein at least one of the user-specified behavior requirement or a user-specified transformation requirement includes a semantic tag, and further comprising instructions that if executed enable the system to:

determine which transformations to apply to a sub-segment of the recognized word sequence according to a semantic tag associated with the sub-segment.

20. The article of claim 17, wherein the user-specified behavior requirement specifies a first transformation for a first portion of an input grammar, and a second transformation for a second portion of the input grammar.
