<p>A radio subscriber communication unit (14) maintains an annunciation memory (60, 126) which stores a repertoire of annunciations. When the subscriber unit (14) receives annunciation data messages from a communication network (10), a particular one of the annunciations is selected and presented to the user of the subscriber unit (14). An audible segment (134) of the annunciation is passed through a vocoder (62), amplified (64), and routed to a speaker (66) for presentation to the user. When annunciations are repeated (148), a second message may be received to instruct subscriber unit 14 to cease (150) presenting an annunciation. <IMAGE></p> |
