What is a Trigram Specialty Vocabulary?
The most widely used statistical model of language is the trigram model, in which an estimate of the likelihood of a word is made solely on the identity of the preceding two words in the utterance. The strengths of the trigram model come from its success at capturing local constraints, the ease by which it may be constructed from text corpora, and from its computational efficiency in use. Such a model has been at the heart of speech recognition systems since the pioneering work at IBM in the early 1980s. Trigram models have also been applied in optical character recognition applications, and in machine translation. Now let’s try this again in plain English. Speech recognition programs are really just playing the odds to predict what you actually said. They narrow down what you say based on the sounds you make and how high on the vocabulary scale the words are that match the sounds. A short list of possible words are then compared to a data set (the language model) and the speech progra
