Documentation

This object implements an n-gram language model. The n-gram data structures are encapsulated in the ngram member variable (see LMNGram class). Methods are provided to read a LM file in ARPA format or in Noway binary format. A method is provided to calculate a LM prob (with backoff) for a given sequence of words.
