  • Method and apparatus to provide a hierarchical index for a language model data structure
    Publication number: 20050055199
    Abstract: A method for storing bigram word indexes of a language model for a consecutive speech recognition system (200) is described. The bigram word indexes (321) are stored as a common two-byte base with a specific one-byte offset to significantly reduce storage requirements of the language model data file. In one embodiment the storage space required for storing the bigram word indexes (321) sequentially is compared to the storage space required to store the bigram word indexes as a common base with specific offset. The bigram word indexes (321) are then stored so as to minimize the size of the language model data file.
