A diphone is the last part of one phoneme followed by the first part of another. Either phoneme could be silence, and they can be the same phoneme. Diphthongs include diphones in them.

This list of the top 4,800 words by frequency in English speech was used with CMUDICT to create the following list of 1,052 diphones without dipthongs by approximate prevalence.
