15. A computer-implemented method comprising: a processor setting probabilities for sequences of position-dependent phonetic tokens through steps comprising developing cross-word counts for sequences of position-dependent phonetic tokens that span multiple words based on probabilities of sequences of multiple words that the sequences of position-dependent phonetic tokens span; and the processor storing the probabilities for sequences of position-dependent phonetic tokens as part of a position-dependent phonetic language model.
18. The computer-implemented method of claim 15 further comprising using the position-dependent phonetic language model to identify a sequence of position-dependent phonetic tokens from a speech signal.
