Method of automatic recognition of a spelled speech utterance

Abstract

The invention relates to a method of automatic recognition of an at least partly spelled speech utterance, with a speech recognition unit (2) based on statistical models that include a linguistic speech model (6). To improve this method in such a way that in addition to a convenient entry, also a reduced speech recognition error rate is achieved, there is proposed that after the at least partly spelled speech utterance has been entered, the speech recognition unit (2) determines a first recognition result for the whole speech utterance; individually recognized letters are sent to the user for him to acknowledge or reject; after a letter has been acknowledged, the linguistic speech model (6) is adapted, which linguistic speech model, after its adaptation, determines the number of letters that can be allowed as followers of the acknowledged letters and assumes the correctness of letters already acknowledged; the speech recognition unit (2) determines a further recognition result for the speech utterance by means of the adapted linguistic speech model (6), from which result the next letter to be sent to the user is determined, so that he can acknowledge it.
