This study focused on designing an intelligent living-space with automatic control system to control all home appliances in the space. First of all, the system was constructed with two parts; one is remote control mechanism with Bluetooth (BT) module mounting on both master controller module (remote controller) and slave receiver module on every home appliance, the other is to design the remote controller with speech-recognition and function of self-learning human voice so that people could directly give command to control appliances Therefore, the technique of BT communication and speech-recognition microprocessor became the most important in this study. After implementing the finished projects, the whole system was proved successful and the final result of this research has achieved both National patent and National Award of Practical Projects Design authorized by Taiwan Education Ministry.
