1. A method comprising: identifying a position-dependent phonetic description of each word in a word language model, each position-dependent phonetic description comprising at least one position-dependent phonetic token, each position-dependent phonetic token comprising a phone and a position identifier that identifies a position within a syllable; using probabilities for words and probabilities for sequences of words in the word language model to set probabilities for position-dependent phonetic tokens and probabilities for sequences of position-dependent tokens to construct a position-dependent phonetic language model; and storing the position-dependent phonetic language model.
