Abstract: Present-day limitations of the conventional touch-tone keypad are overcome permitting alphabetic information to be entered into a distant computer. The caller speaks a speech portion into a telephone handset, and then types out the speech portion on the touch-tone keypad. The computer receiving the call converts the spoken voice in-formation into a form suitable for additional digital processing, as by extracting speech-recognition features from the spoken informa-tion (32). The computer processes the typed numeric string into a list of all the possible combinations of characters it could represent (31). The extent of correlation between the features of the spoken speech portion and each of the combinations is determined (33), and the combination having the highest correlation is taken to be the speech portion entered by the user (34).

Abstract: ABSTRACT OF DISCLOSURE      Office furniture units, particularly desks, are fabricated of panel members cut from standard pre-finished flat wood panels, to their precise final configuration, by an NC controlled automatic router, including all holes, recesses and the like required in each panel member. The panel members have configurations which constitute the intelligence to assure their precise alignment as they are subassembled into furniture panel components by securing the appropriate panel members together in multiple layers, and for reception of two-part mechanical fasteners in appropriate positions to insure proper positioning of the panel components with respect to one another in the final assembly of the panel components into a functional office furniture unit. The panel components are assembled with one another in T-joint fashion, with the edge surface of one panel abutting a major side surface of the respective transverse panel to which being joined, using cam-type fastener components which secure the panel components together in firm edge-abutment relationships.  The multiple layers of panel members provide reinforcement and rigidity of the panel components where necessary, as well as visual thickness effect  In each instance, one of the panel members is of the configuration of the final panel component.  Several of the panel members include edge tabs which protrude laterally of the respective subassembled components for interfitting in recesses provided in mating panels to provide enhanced shear strength across the T-joint interpanel connections in the final assembly of the furniture unit.  The structure and method also provide flexibility to produce differing furniture items in successive machining and assembly operations, for rapid production of a variety of different products "to order" from a single machine production line.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus is described for individually inserting successive components of a series of components having mounting legs by movement  of the components along an insertion direction to introduce the mounting legs into holes in a substrate at an insertion station. The apparatus includes a guide for guiding a strip of components along a feedpath generally normal to the insertion direction with the mounting legs oriented in the direction of the substrate surface. The strip is advanced stepwise after each insertion operation to position the next successive component of the strip at the insertion station. The carrier web between a component to be inserted and the next successive upstream component is centered relative to a web shearing line, a first cutting element at the insertion station being arranged for abutment against a carrier edge or line proximate to the mounting legs for preventing movement of that portion of the carrier web upstream of the shearing line in the insertion direction. The strip is moved relative to the cutting element to permit the strip to advance the next successive component to be inserted to the inserted station without being blocked by the first cutting element. A plunger is provided which moves along the insertion direction to shear the carrier web when the plunger is driven into engagement with that portion of the carrier web downstream of the shearing line and move it below the carrier edge or line. An insertion spoon carries the component towards and inserts it through the substrate.
