Abstract

Embodiments of the present invention address deficiencies of the art in respect to virtualization and provide a novel and non-obvious method, system and computer program product for annotation of street grammar in speech enabled navigation devices. In an embodiment of the invention, a pre-processing street grammar annotation system can be provided. The system can include an annotated street grammar storage that contains street root names wherein each street root name has more than one street suffix associated with said street root name, and a street annotation pre-processor wherein the street annotation pre-processor contains logic enabled to annotate a set of street suffixes to a street root name prior to processing a voice input in a speech enabled navigation device, wherein the street root name has more than one street suffix associated with said street root name.

Claims

1. A method of constructing street grammar comprising annotating a street root name with a set of street suffixes prior to processing a voice navigation input in a speech enabled navigation device, wherein the street root name has more than one street suffix associated with said street root name.

2. The method of claim 1 wherein annotating a street root name with a set of street suffixes comprises merging a street root name with one or more street suffixes into an annotated street grammar storage.

3. A pre-processed street grammar data processing system comprising:

a street annotation pre-processor wherein the street annotation pre-processor contains logic enabled to annotate a street root name with a set of street suffixes prior to processing a voice navigation input in a speech enabled navigation device, wherein the street root name has more than one street suffix associated with said street root name; and

an annotated street grammar storage coupled to the street annotation pre-processor that contains street root names wherein each street root name has more than one street suffix associated with said street root name.

4. A computer program product comprising a computer usable medium embodying computer usable program code for constructing street grammar, the computer program product comprising computer usable program code for annotating a street root name with a set of street suffixes prior to processing a voice navigation input in a speech enabled navigation device, wherein the street root name has more than one street suffix associated with said street root name.

5. The computer program product of claim 4, wherein the computer usable program code for annotating a street root name with a set of street suffixes comprises merging a street root name with one or more street suffixes into an annotated street grammar storage.
