Detailed Description

Building triphones for a dictionary.

This is one of the more complicated parts of a cross-word triphone model decoder. The first and last phones of each word get their left and right contexts, respectively, from other words. For single-phone words, both its contexts are from other words, simultaneously. As these words are not known beforehand, life gets complicated.

I doubt whether it is correct because the compressed map has not been checked.
