Abstract

A radio subscriber communication unit maintains an annunciation memory which stores a repertoire of annunciations. When the subscriber unit receives annunciation data messages from a communication network, a particular one of the annunciations is selected and presented to the user of the subscriber unit. An audible segment of the annunciation is passed through a vocoder, amplified, and routed to a speaker for presentation to the user. When annunciations are repeated, a second message may be received to instruct subscriber unit to cease presenting an annunciation.
