1. A method for recognizing a phonetic sequence of sounds comprising:

  • a) sending the phonetic sequence of sounds to a neural network implemented on a computer,b) forming by the neural network a sequence of features from the phonetic sequence taking into account phonetic stored information,c) selecting a reference combination of features from saved semantical information on the basis of the sequence of features formed in step b), said reference combination of features having a defined meaningful content, and comparing the sequence of features formed in step b) with the reference combination of features,d) repeating step c) with new reference combinations of features until, by minimizing contradictions, a reference combination of features that substantially agrees with the sequence of features formed in step b) is found, ande) if the reference combination of features found in step d) matches one of a plurality of predetermined acceptable combinations of features,then outputting the meaningful content of the reference combination of features found in step d) as a result,else forming a new sequence of features by the neural network in accordance with step b), and repeating steps c) to e).
