Dear sir,
This project is not simple as it sounds, it involves real time speech synthesis, Digital Recording,digital storage,digital playback etc apart from interfacing to phone lines. I have designed "Voice based Intruder Alarm" which dials out the House Owner's Number and cops number in case of Break in and plays "Alert, Alert, Intruder in the house" message via a Regular Phone Line/GSM . I can successfully do this project and help you in Phase 1 and Phase 2. Prototype Charges (Material + shipping) are additional. My time line is 10 days for Design phase and 7 days for prototype and am very punctual over set deadlines.
