Audio communication system and method

Abstract

Systems and methods for audio communication are disclosed. The system includes a plurality of transducer units and plurality of sensors adapted to be located in a plurality of sites/spaces to which service should be provided by the system. The plurality of transducer units are capable of emitting/directing and focusing ultra-sonic signals to respective coverage zones in the sites, such that localized (confined) sound field can be formed at selected spatial position in the coverage zones by utilizing sound from ultrasound technique. The sensors are associated with respective sensing volumes in the sites and are operable to obtain sensory data indicative of spatial arrangement of elements/object at the sensing volumes within the sites. The system includes: a user detection module for processing the sensory data from the sensors to detect a user within the sensing volumes; gesture detector for determining one or more vocal and/or non-vocal gestures of said user; an audio session manager adapted to determine sound data for transmission to said user in association with said one or more gestures; and an output sound generator adapted to selecting a transducer unit for serving the user, and operating the selected transducer to produce audible sound with said sound data to be provided to said user.
