发明名称 PAGING RECEIVER FOR STORING DIGITIZED VOICE MESSAGES
摘要 A selective call paging receiver (10) for receiving analog voice information converts the analog information to digital information and stores the digital information in a memory (50) of the paging receiver. In a first embodiment, the paging receiver (10) includes a hardware controlled decoder (14) and an audio producing module (64). The memory (50) is divided into a plurality of fixed storage areas to allow the decoder (14) to store a digitized voice message in one of the fixed storage area. If the storage capacity of the fixed storage area is not filled, the audio producing module (64) fills the remainder with a digitized predetermined audio signal. In a second embodiment, the paging receiver includes a microprocessor controlled decoder (28). The microprocessor (28) stores a digitized voice message in the memory (50), depending upon the length of the voice message, thus eliminating the fixed storage area.
