  • Compression of language model structures and word identifiers for automated speech recognition systems
    Patent number: 7171358
    Abstract: A method compresses one or more ordered arrays of integer values. The integer values can represent a vocabulary of a language mode, in the form of an N-gram, of an automated speech recognition system. For each ordered array to be compressed, and an inverse array I[.] is defined. One or more spilt inverse arrays are also defined for each ordered array. The minimum and optimum number of bits required to store the array A[.] in terms of the split arrays and split inverse arrays are determined. Then, the original array is stored in such a way that the total amount of memory used is minimized.
