Abstract:     A method of, and apparatus for, operating an automatic message recognition system. In accordance with the method the following steps are executed: a user's speech is converted to a first signal; a user's handwriting is converted to a second signal; and the first signal and the second signal are processed to decode a consistent message, conveyed separately by the first signal and by the second signal, or conveyed jointly by the first signal and the second signal. The step of processing includes the steps of converting the first signal into a plurality of first multi-dimensional vectors and converting the second signal into a plurality of second multi-dimensional vectors. For a system employing a combined use of speech and handwriting the step of processing includes a further step of combining individual ones of the plurality of first multi-dimensional vectors and individual ones of the plurality of second multi-dimensional vectors to form a plurality of third multi-dimensional vectors. The multi-dimensional vectors are employed to train a single set of word models, for joint use of speech and handwriting, or two sets of word models, for sequentially employed or merged speech and handwriting.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent is:     1. A message recognition system comprising:
  • a first transducer for converting a user's speech to a first signal;
  • a second transducer for converting the user's handwriting to a second signal; and
  • a data processor, having a first input coupled to the first signal and a second input coupled to the second signal, for processing the first signal and the second signal to identify an informational content of the first signal and the second signal, said data processor including,
    • a first likelihood estimator for generating a first list comprised of one or more probable messages conveyed by the informational content of the first signal;
    • a second likelihood estimator for generating a second list comprised of one or more probable messages conveyed by the information content of the second signal;
  • wherein a probable message is comprised of at least one word;
    • a likelihood merger for selectively merging the first list and the second list to form a third list;
    • a decoder for selecting from the third list a most probable one of the probable messages to be an output message; and
    • means for outputting the output message.
