For example, the fundamental element of speech input is the phoneme, the smallest part of a word that still has a distinct identity.
Every word is made up of a set of such phonemes, which serve as a fingerprint for that word.
From here it scans through a list of possible matches in a stored dictionary. Regular Operators Computers are flawed by their need for unambiguous input. Regular operators, a combination of wildcard and boolean logic operators, allow for a more flexible interface for the user. In the specific field of language, text or speech, input an extremely useful programming tool is the edit distance algorithm. This algorithm is used to determine the shortest number of letter insertions, deletions, or changes that need to be made to transfer one string to another.
