13. A computerized system for generating a spatially indexed grammar associated with place names, the computerized system comprising: a processor; a memory coupled to the processor; a tile-code generation module which partitions a geographical area into a plurality of finite non-overlapping regions and assigns an index to each of the finite regions, the index configured to be determined using a coordinate system by interleaving a first digit of a horizontal coordinate associated with one of the finite regions with a first digit of a vertical coordinate associated with one of the finite regions, interleaving a second digit of the horizontal coordinate with a second digit of the vertical coordinate, interleaving a third digit of the horizontal coordinate with a third digit of the vertical coordinate, and adding a fourth digit of the horizontal coordinate; a feature generation module which classifies a number of points on each of the place names within each of the finite regions, each of the points comprising names of first level identifiers in an area defined by the finite regions; a sorting and de-duping module which sorts the place names associated with the place names in each of the finite regions and removes one or more duplicate points within each of the finite regions; and a tile file generation module which generates a list of features and associated speech recognition grammars for at least a first and a second of the finite regions, after the features are sorted and the duplicate features are removed from the first and the second of the finite regions.
