Abstract:
An intelligent keyboard interface having human language processing capability which is responsive to commands designated by voice input and keyboard input to change keypad displays on a keyboard, the intelligent keyboard interface comprising:an intelligent module automatically responsive to a combination of voice input and keystroke input to recognize and interpret the combination into command signals via a Hidden Markov model (HMM), the HMM comprising: a first Hidden Markov model including one or more first states having one or more first arcs for connecting the one or more first states, the one or more first arcs representing output string of voice; a second Hidden Markov model including one or more second states having one or more second arcs for connecting the one or more second states, the one or more second arcs representing output string of keys; one of more third arcs connecting the one or more first states with the one or more second states, the one or more third arcs producing an empty output string, the one or more third arcs traversed when an interpretation state between the output string of the voice and the output string of keys are switched; and one or more display screens embedded in one or more keypads on a keyboard capable of displacing contents responsive to the command signals transmitted from the intelligent module, wherein the displayed contents represent user selectable functionality for performing functions associated with the combination of the voice input and keyboard input.
