Text-to-speech preprocessing and conversion of a caller's ID in a telephone subscriber unit and method therefor

摘要

A telephone subscriber unit (22) includes a caller identification device (120), a memory unit (114), a pre-processor (124) and a text-to-speech synthesizer (TTS) (110). The caller identification device (120) receives caller ID information of a calling party in a first textual format and stores the caller ID information in the memory unit (114) The pre-processor (124) converts textual caller ID information from the first data format to a second data format suitable for text-to-speech synthesis by the text-to-speech synthesizer (110). The text-to-speech synthesizer (110) generates audible caller ID information responsive to receiving the textual caller information.
