This project aims to develop a system which allows users to speak without using microphone to control home appliances. Users can use natural language sentences (may contains suffix words) as input for the proposed system. In the above scenario, the user does not need to know the complex control methods and related functions of each household electrical appliance. Using multidimensional space audio recording technology, results of intent recognition and speech recognition can work with coupling services. Moreover, a dialogue system can feedback a related sentence for the user to confirm the final operations of appliances. Research issues include: (1)Complete the wireless multi-channel sound catching module; (2)Complete the multidimensional audio recording with cloud computing; (3)Complete user intent recognition for cloud information appliances; (4)Complete cloud speaker recognition on cloud; (5)Complete cloud appliances operating feedback dialogue system; (6)Complete the 3D interactive virtual waiter and scene design.
