This chapter presented home appliances control system for independent life of the severely disabled person. In particular, the developed system can be operated by inarticulate speech and a non-voice rejection method for reliable VAD in a real environment with extraneous sounds such as coughing and breathing.

Our experiment results indicate that the false alarm rate is 4.9% with no miss-errors in which voice is determined to
