Abstract

A system enables a transcriptionist to replace a first written form (such as an abbreviation) of a concept with a second written form (such as an expanded form) of the same concept. For example, the system may display to the transcriptionist a draft document produced from speech by an automatic speech recognizer. If the transcriptionist recognizes a first written form of a concept that should be replaced with a second written form of the same concept, the transcriptionist may provide the system with a replacement command. In response, the system may identify the second written form of the concept and replace the first written form with the second written form in the draft document.

Claims

1. A computer-implemented method for use with a document tangibly stored in a first computer-readable medium, the method comprising:

(A) accessing the first computer-readable medium to identify a first phrase within the document, the first phrase representing a first written form of a concept;

(B) identifying a two-way mapping between the first phrase and a second phrase tangibly stored in a second computer-readable medium, the second phrase representing a second written form of the concept;

(C) replacing the first phrase with the second phrase in the document on the first computer-readable medium; and

(D) after (C), replacing the second phrase with the first phrase in the document on the first computer-readable medium.

2. The method of claim 1, further comprising:

(D) before (C), receiving an instruction from a user to modify the first phrase;

wherein (C) is performed in response to receipt of the instruction; and

wherein the instruction does not include the second phrase.

3. The method of claim 2, wherein the instruction comprises an instruction generated by the user using a single keystroke.

4. The method of claim 1, further comprising:

(D) generating at least part of the document using an automatic speech recognizer, the at least part of the document including the first phrase.

5. An apparatus for use with a document tangibly stored in a first computer-readable medium, the apparatus comprising:

means for identifying a first phrase within the document, the first phrase representing a first written form of a concept;

means for identifying a two-way mapping between the first phrase and a second phrase tangibly stored in a second computer-readable medium, the second phrase representing a second written form of the concept;

means for replacing the first phrase with the second phrase in the document; and

means for replacing the second phrase with the first phrase in the document.

6. A computer-implemented method for use with a document tangibly stored in a first computer-readable medium, the method comprising:

(A) accessing the first computer-readable medium to identify a first phrase within the document, the first phrase representing a first written form of a concept;

(B) determining whether a plurality of text keys tangibly stored in a second computer-readable medium includes a matching text key having at least a predetermined degree of similarity to the first phrase; and

(C) if the plurality of text keys is determined to include the matching text key, then;

(i) accessing the second computer-readable medium to identify a text value associated with the text key; and

(ii) replacing the first phrase with the text value in the document on the first computer-readable medium; and

(D) after (C), replacing the text value with the matching first phrase in the document on the first computer-readable medium.

7. The method of claim 6, further comprising:

(D) before (C), receiving an instruction from a user to modify the first phrase;

wherein (C) is performed in response to receipt of the instruction; and

wherein the instruction does not include the text value.

8. The method of claim 7, wherein the instruction comprises an instruction generated by the user using a single keystroke.

9. The method of claim 6, further comprising:

(E) generating at least part of the document using an automatic speech recognizer, the at least part of the document including the first phrase.

10. The method of claim 6, wherein (C)(i) comprises accessing the second computer-readable medium to identify the text value based on a context of the first phrase in the document.

11. The method of claim 6, wherein (C)(i) comprises identifying the second computer-readable medium to identify a text value from among a plurality of text values associated with the text key.

12. An apparatus for use with a document tangibly stored in a first computer-readable medium, the apparatus comprising:

means for identifying a first phrase within the document, the first phrase representing a first written form of a concept;

means for determining whether a plurality of text keys tangibly stored in a second computer-readable medium includes a matching text key having at least a predetermined degree of similarity to the first phrase;

means for identifying a text value associated with the text key and replacing the first phrase with the text value in the document if the plurality of text keys is determined to include the matching text key;

means for replacing the text value with the matching first phrase in the document after replacing the first phrase with the text value.

13. A computer-implemented method comprising:

(A) identifying a first phrase, the first phrase representing an expanded written form of a concept;

(B) receiving an instruction from a user to modify the first phrase;

(C) in response to receipt of the instruction, identifying a second phrase representing an abbreviated written form of the concept; and

(D) replacing the first phrase with the second phrase;

wherein the instruction does not include the second phrase.

14. The method of claim 13, further comprising:

(E) after (C), replacing the second phrase with the first phrase.

15. The method of claim 13, wherein the instruction comprises an instruction generated by the user using a single keystroke.

16. The method of claim 13, wherein the first phrase comprises a first phrase in a document, and wherein (D) comprises replacing the first phrase with the second phrase in the document.

17. The method of claim 16, further comprising:

(E) generating at least part of the document using an automatic speech recognizer, the at least part of the document including the first phrase.

18. The method of claim 16, wherein (C) comprises identifying the second phrase based on a context of the first phrase in the document.

19. The method of claim 13, wherein (D) comprises identifying a second phrase from among a plurality of second phrases representing the concept.

20. An apparatus comprising:

means for identifying a first phrase, the first phrase representing an expanded written form of a concept;

means for receiving an instruction from a user to modify the first phrase;

means for identifying a second phrase representing an abbreviated written form of the concept in response to receipt of the instruction; and

means for replacing the first phrase with the second phrase;

wherein the instruction does not include the second phrase.

21. A computer-implemented method comprising:

(A) generating a document using an automatic speech recognizer;

(B) receiving an instruction from a user to modify a first phrase in the document, the first phrase representing a first written form of a concept;

(C) identifying a two-way mapping between the first phrase and a second phrase, the second phrase representing a second written form of the concept;

(D) in response to receipt of the instruction, replacing the first phrase with the second phrase in the document; and

(E) after (D) replacing the second phrase with the first phrase in the document.

22. The method of claim 21, wherein the first phrase is an abbreviated form of the second phrase.

23. The method of claim 21, wherein the second phrase is an abbreviated form of the first phrase.

24. An apparatus comprising:

means for generating a document using an automatic speech recognizer;

means for receiving an instruction from a user to modify a first phrase in the document, the first phrase representing a first written form of a concept;

means for identifying a two-way mapping between the first phrase and a second phrase, the second phrase representing a second written form of the concept;

means for replacing the first phrase with the second phrase in the document in response to receipt of the instruction; and

means for replacing the second phrase with the first phrase in the document.
