Audible Message Generator, Digitally Controlled

This is a digitally controlled generator of voiced messages which can be simultaneously sent to several channels.

Frequent regular samples of basic sounds, syllables, words or phrases are combined and prestored in an interleaved fashion on tracks of a recirculating store containing a clock track and a timing reference mark. All clock phases are derived from this track by logic circuits.

Each signal, having been sampled and recorded with a particular clock phase, is read from the interleave on request by strobing with the proper derived clock. Thus, a number of messages are simultaneously generated each revolution and gated to appropriate output channels.

The circulating store can also be used to buffer digital control signals from external equipment, thus simplifying the synchronizing and timing control circuits.
