1. A method for using voice input to data processing machine of the type having a visual display screen and means for selectively displaying images on the screen comprising the steps of generating a set of visible dividers on the screen which segregate the screen into sectors which can be uniquely discribed by one or more alphanumeric symbols; providing a storage location for data bits from which a display is to be produced on the screen; functionally dividing the storage location into a plurality of storage portions at least equal in number to the number of sectors so that addresses in the storage location can be functionally correlated with the positions of image features displayed on the screen; providing a voice responsive transducer for converting received utterances into electrical signals representative of speech patterns; storing a dictionary of speech patterns of a plurality of utterances including utterances recognizable as the alphanumeric symbols identifying the sectors and preselected instructions; providing the display screen with touch responsive means so that touching the screen identifies a location to the machine, whereby utterances can be employed in conjunction with touch to efect display changes; comparing the speech patterns of an utterance received by the transducer with the patterns stored in the dictionary and producing outputs of recognized utterances as an instruction or a sector identification followed by an instruction, recognition being defined as a close match of patterns; and executing the instruction.
