Claim 6:
6. The method according to claim 1, wherein: the step b) comprises determining whether the recognized word is spelled correctly, the at least one confusion matrix includes a plurality of character values, and the step d) comprises, if the recognized word is spelled incorrectly: i) obtaining, for each character sequence in each one of the at least one reference word, a character value representing a likelihood that the character sequence of the at least one reference word is recognized as the corresponding character sequence in the incorrectly spelled recognized word, wherein each of the character sequence of the at least one reference word and the character sequence of the incorrectly spelled recognized word comprises at least one character position, respectively, ii) establishing a reference word recognition value based on the obtained character values, and iii) repeating steps i) and ii) for each reference word, each reference word being associated with a corresponding reference word recognition value, each replacement word value comprising a corresponding reference word recognition value.
