A system (10) and method (40) for providing audible caller information to telephone service subscribers is presented. The system (10) includes a pre-processor (28) that converts textual caller information from a first data format to a second data format suitable for text-to-speech synthesis (TTS). The pre-processor (28) can be incorporated in a service node/intelligent peripheral (SN/IP) (24) in an advanced intelligent network (AIN). In this configuration, the pre-processor (28) can be used to convert caller-ID with name database entries into a predetermined TTS format. The TTS formatted information can be provided to a TTS synthesized (30) included in the SN/IP (24). In conjunction with a switching service point (SSP) (20), the pre-processor (28) can provide a talking call-waiting feature to subscribers with significantly improved intelligibility.
