The voice activated thermostat was designed so the temperature in a house could be set without having to touch the thermostat. This is especially useful for a quadriplegic who would like to change the temperature of the room he is in. For simplicity, it was designed using VCP200 speaker-independent word recognizer chip. This chip comes pre-programmed with a limited number of words, so programming of words was not necessary. Every time the activation word is said the digital thermostat changes by one degree.
