22. A method for recognizing a sequence of spoken character signals according to claim 21 wherein the generation of the modified trial word further comprises forming a second signal responsive to the absence of a next most probable character in said detected mismatched position of the array; replacing the character in said detected mismatched position of the stored trial word with the most probable character of the detected mismatched position of the array responsive to said second signal; shifting the detecting mismatched position left to the next left position in which there is a next most probable character in the array for substitution responsive to said second signal; and substituting said next most probable character in said next left position of the array in the next left position of the stored trial word responsive to said second signal.

A method for recognizing a sequence of spoken character signals according to claim 22 wherein said directory store searching step further comprises detecting the rightmost first occurring mismatched position of the current and all preceding directory searches and storing the best trial word corresponding to said detected rightmost first occurring mismatched position of the current and all preceding directory searches; and wherein the generation of the modified trial word further comprises forming a third signal responsive to the absence of a next most probable character in the leftmost position of the array; forming a modified trial word from said best trial word by replacing the character in said detected rightmost first occurring mismatched position of all preceding directory store selected sequence reference word searches in the best trial word with an ignore mismatch character responsive to said third signal.
