Abstract
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.
Claims20
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.
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.
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.
