ABSTRACT The invention provides a method of and apparatus for recognition of words in sound, with no preprogramming of a communication dictionary of words. The method consists in classifying the sounds forming the uttered words into eight phonetic classes with an indication of the possible presence of diphthongs, starting from an acoustic- phonetic analysis of the sounds themselves. To recognize the uttered words the sequence of classes found are analyzed by search-tree algorithms for pattern matching with sequences of classes corresponding to vocabulary words, and optionally by dynamic programming algorithms. The detected phonetic classes include silence, voiced fricatives, unvoiced fricatives, plosives, affricates, nasals, semivowels and vowels.
