The method according to the invention for word recognition in sequences of N characters, of which one or more characters may be ambiguous, uses a memory (15), a display (13), and a processor device (12). The memory comprises n-grams (character chains with a length n) and frequency values associated with said character chains, with the total number of all n-grams in a language sample used for word recognition being used as the frequency value of an n-gram. The display (12) shows selected n-grams and/or recognized words, wherein the processor device (12) is connected to the memory (15) and the display (13). A list L of all n-grams with N characters that may be formed from the individual characters in the N-character sequence, taking into account the ambiguity of the characters present in said sequence, is prepared from an examined character sequence. All n-gram combinations with a word probability of zero are removed from the list L of possible n-gram combinations, wherein the word probability p = ? pn is determined from the n-grams included in the character sequence with n = 1 to N-1. The words (14) represented by the remaining n-gram combinations from the list L are displayed. |
