dc.description.abstract

The Telephone Voice Alert is divided into six parts: the ring detector, controller, voice memory, synthesizer, speaker, and power supply subsystems. These all interact together to produce a voice signal whenever a ring signal is detected. By beginning from the system function and analyzing the components as we break the system into subsystems, we find that the trade-off between system cost and system "effectiveness" minimizes to prove Configuration A (digital voice reproduction) a more effective means. Further testing and development is necessary, however, as the design must be "fine-tuned" in order to insure proper function.
