  12. I believe the term you are looking for is 'triphone.'  Kai Fu Lee
  13. made a big deal out of triphones in his PhD Thesis on the Sphinx
  14. system.

  16. A triphone is a context-dependant phoneme.  You would think that there
  17. are on the order of 40 to 50 cubed of these in English, but quite a few
  18. of these combinations never appear.  I think there are around 2000 of
  19. them that are actually used in English.
