Abstract

A method, system and apparatus for text grouping in a disambiguation process. A text grouping method for use in a disambiguation process can include producing a phonetic representation for each entry in a text list, sorting the list according to the phonetic representation, grouping phonetically similar entries in the list, and providing the sorted list with the groupings to the disambiguation process. The producing step can include producing a phonetic representation for each word in the text list. The producing step also can include producing a phonetic representation for each phrase in the text list.

Claims

1. A text grouping method for use in a disambiguation process, the method comprising the steps of:

producing a phonetic representation for each entry in a text list;

sorting said list according to said phonetic representation;

grouping phonetically similar entries in said list; and

,

providing said sorted list with said groupings to the disambiguation process.

2. The method of claim 1, wherein said producing step comprises the step of producing a phonetic representation for each word in said text list.

3. The method of claim 1, wherein said producing step comprises the step of producing a phonetic representation for each phrase in said text list.

4. The method of claim 1, further comprising the step of flagging each grouping in said list as requiring disambiguation.

5. The method of claim 1, further comprising the step of, for each similar phoneme across different entries in said grouping, substituting said similar phoneme with a first occurrence of said phoneme.

6. The method of claim 5, further comprising the step of storing said similar phoneme in a temporary variable.

7. A speech system configured for disambiguation, the system comprising:

a speech application configured for coupling to a speech engine;

a disambiguation processor associated with said speech application; and

,

text grouping logic programmed to produce an optimized grammar for use by said disambiguation processor in disambiguating similar sounding text.

8. The system of claim 7, wherein said similar sounding text comprises homophonic words.

9. The system of claim 7, wherein said similar sounding text comprises oronymic phrases.

10. The system of claim 7, wherein said text grouping logic comprises logic to sort and group entries in a text list according to a phonetic representation for each of said entries.

11. A machine readable storage having stored thereon a computer program for text grouping in a disambiguation process, the computer program comprising a routine set of instructions which when executed by a machine causes the machine to perform the steps of:

producing a phonetic representation for each entry in a text list;

sorting said list according to said phonetic representation;

grouping phonetically similar entries in said list; and

,

providing said sorted list with said groupings to the disambiguation process.

12. The machine readable storage of claim 11, wherein said producing step comprises the step of producing a phonetic representation for each word in said text list.

13. The machine readable storage of claim 11, wherein said producing step comprises the step of producing a phonetic representation for each phrase in said text list.

14. The machine readable storage of claim 11, further comprising an additional set of instructions which when executed by the machine causes the machine to further perform the step of flagging each grouping in said list as requiring disambiguation.

15. The machine readable storage of claim 11, further comprising an additional set of instructions which when executed by the machine causes the machine to further perform the step of, for each similar phoneme across different entries in said grouping, substituting said similar phoneme with a first occurrence of said phoneme.

16. The machine readable storage of claim 15, further comprising an additional set of instructions which when executed by the machine causes the machine to further perform the step of storing said similar phoneme in a temporary variable.
