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

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