1. A method for segmenting a stream of text into segments using a plurality of language models, the stream of text including a sequence of blocks of text, the method comprising: scoring the blocks of text against the language models to generate language model scores for the blocks of text, the language model score for a block of text against a language model indicating a correlation between the block of text and the language model; generating language model sequence scores for different sequences of language models to which a sequence of blocks of text may correspond, a language model sequence score being a function of the scores of a sequence of blocks of text against a sequence of language models; selecting a sequence of language models that satisfies a predetermined condition; and identifying segment boundaries in the stream of text that correspond to language model transitions in the selected sequence of language models.

The method of claim 1, wherein the language models are generated by: clustering a stream of training text into a specified number of clusters; and generating a language model for each cluster.
