Design and performance evaluation of voice activated wireless home devices

The design and performance evaluation of voice activated wireless home devices are presented in this paper. The speech recognizer is built using hidden Markov model technology and tested under various kinds of noise. An example of how the built speech recognizer is integrated with X.10 protocol based light controller is given to demonstrate the open architecture of the system. Results from testing and experimentation show that it is feasible to use voice as the unified control method to control home devices and appliances
