System design for speech recognition and generation

A durable and inexpensive, integrally molded key rack for accessibly storing and conveniently organizing keys is adapted for location in and attachment to the following block of desk or filing cabinet drawers. Projecting rearwardly of the rear face of the key rack are a pair of upright clips for securing the rack to the following block and projecting forwardly of the front face are a pair of spaced, slotted, horizontally-extending, key-receiving projections for holding keys. The rack is formed with a first set of ribs extending about the periphery of the rear face and a second set of ribs extending between the clips and the key-receiving projections. The first and second sets of ribs and the key-receiving projections combine to rigidify the key rack. By molding consecutive numerical indicia in the key rack adjacent each slot and attaching a correspondingly numbered chart to the front face of the rack, the molded number adjacent each key may be matched with its associated lock or machine, thereby providing a convenient correlation guide.
