Abstract
Method for recognizing speech includes receiving a speech phrase, generating a signal being representative to the speech phrase, pre-processing and storing the signal with respect to a determined set of rules, generating from the pre-processed signal at least one series of hypothesis speech elements, and determining at least one series of words being most probable to correspond to the speech phrase by applying a predefined language model to at least said series of hypothesis speech elements. The determination of the series of words includes determining at least one sub-word, word, or a combination of words most probably being contained as a seed sub-phrase in the received speech phrase. The determination continues with determining words or combinations of words that are consistent with the seed sub-phrase as at least a first successive sub-phrase, which is contained in the received speech phrase, by using and evaluating additional and paired and/or higher order information between the sub-phrases, thereby decreasing the burden of searching.
