Abstract
A method (and system) to achieve automatic language recognition that includes the steps of introducing language in the form of strings to a mechanism that converts the language to electrical signals derived from the strings introduced, which electrical signals are the electrical analog of words in the strings; analyzing the electrical signals to achieve automatic recognition of the letters in a word of the text on the basis of an integration of (a) channel characteristics in the form of probabilities that the particular letter is a corruption of another letter, (b) the probabilities of the letter occurring serially with other recognized letters that precede the letter being analyzed, and (c) lexical information in the form of acceptable words represented as a graph structure and presenting as output a reproduction of the text introduced and analyzed.
