... states of each of the two models are unseen and must be inferred from the words. The problem of language understanding, then, is to recover the most likely meaning structure given a sequence of ... sequence of spectra, the relation between the meaning of a sentence and the sequence of words is not a simple linear sequential model. Language is inherently nested, with su...
