A technique is described whereby a phonetic repertoire of each of the letters of the alphabet is determined for use in speech recognition systems. A list is then constructed of all the phonetic realizations that are possible for a given letter in different contexts in an English word. In order to determine the pronunciation of a word from its spelling, it is generally important to know the phonetic values of the English letters. For example, the "t" sound in the word "tough" is produced by the letter "t". However, difficulty arises to produce a "p" sound from the word "hiccough".
