1. A computer-implemented method of decompressing transducer data for speech recognition, comprising: determining a location of a compressed block in an array of compressed blocks of transducer-related data; determining the compression rate of individual compressed entries in the located compressed block; determining a key value to be applied to individual compressed entries of the located compressed block to obtain the uncompressed value of the entry; reading a compressed entry from the compressed block; and decompressing the compressed entry by applying the key value to the compressed entry.
