Enhanced accuracy for speech recognition grammars
View Patent ↗Disclosed herein are methods and systems for recognizing speech. A method embodiment comprises comparing received speech with a precompiled grammar based on a database and if the received speech matches data in the precompiled grammar then returning a result based on the matched data. If the received speech does not match data in the precompiled grammar, then dynamically compiling a new grammar based only on new data added to the database after the compiling of the precompiled grammar. The database may comprise a directory of names.
1. A method comprising:
comparing, via a processor, received speech to a first grammar based on a database, to yield a comparison; and
when the comparison is below a threshold:
compiling a second grammar based on data added to the database after compilation of the first grammar; and
comparing the received speech to the second grammar.
2. The method of claim 1 , wherein the second grammar is stored separately from the first grammar.
3. The method of claim 1 , wherein the data is obtained from one of a table, a list, and an update database.
4. The method of claim 1 , wherein the database comprises a directory of names.
5. The method of claim 1 , further comprising compiling a third grammar when the received speech does not match information in the second grammar.
6. The method of claim 5 , wherein the third grammar comprises updated data from the database.
7. The method of claim 1 , wherein the received speech comprises an acoustic representation of a spoken name.
8. A system comprising:
a processor; and
a computer-readable storage medium having instructions stored which, when executed by the processor, result in the processor performing operations comprising:
comparing received speech to a first grammar based on a database, to yield a comparison; and
when the comparison is below a threshold:
compiling a second grammar based on data added to the database after compilation of the first grammar; and
comparing the received speech to the second grammar.
9. The system of claim 8 , wherein the second grammar is stored separately from the first grammar.
10. The system of claim 8 , wherein the data is obtained from one of a table, a list, and an update database.
11. The system of claim 8 , wherein the database comprises a directory of names.
12. The system of claim 8 , the computer-readable storage medium having additional instructions stored which result in the operations further comprising compiling a third grammar when the received speech does not match information in the second grammar.
13. The system of claim 12 , wherein the third grammar comprises updated data from the database.
14. The system of claim 8 , wherein the received speech comprises an acoustic representation of a spoken name.
15. A computer-readable storage medium having instructions stored which, when executed by a computing device, result in the computing device performing operations comprising:
comparing received speech to a first grammar based on a database, to yield a comparison; and
when the comparison is below a threshold:
compiling a second grammar based on data added to the database after compilation of the first grammar; and
comparing the received speech to the second grammar.
16. The computer-readable storage medium of claim 15 , wherein the second grammar is stored separately from the first grammar.
17. The computer-readable storage medium of claim 15 , wherein the data is obtained from one of a table, a list, and an update database.
18. The computer-readable storage medium of claim 15 , wherein the database comprises a directory of names.
19. The computer-readable storage medium of claim 15 , the computer-readable storage medium having additional instructions stored which result in the operations further comprising compiling a third grammar when the received speech does not match information in the second grammar.
20. The computer-readable storage medium of claim 19 , wherein the third grammar comprises updated data from the database.
