ABSTRACT:
An interactive audio system employs a sound signal processor coupled with a microprocessor as an interactive audio control system. A pair of tranceivers, operated as stereophonic loudspeakers and also as receiving microphones, are coupled with the signal processor for receiving voice commands from a principal user. The voice commands are processed to operate a variety of different devices, such as television, tape, radio or CD player for supplying signals to the processor, from which signals then are supplied to the loudspeakers of the transceivers to produce the desired sound. Additional infrared sensors may be utilized to constantly triangulate the position of the principal listener to supply signals back through the transceiver system to the processor for constantly adjusting the balance of the sound to maintain the "sweet spot" of the sound focused on the principal listener. Additional devices also may be controlled by the signal processor in response to voice commands which are matched with stored commands to produce an output from the signal processor to operate these other devices in accordance with the spoken voice commands. The system is capable of responding to voice commands simultaneously with the reproduction of stereophonic sound from any one of the sources of sound which are operated by the system.
