Abstract

Systems and methods and a device are described that assist in speech communication using a network of proximity filters to suppress the ambient noise contaminating the signal of interest. A unique placement of sensors and a set of techniques that suppress noise in speech and hence can be readily used with plural devices including mobile phones, laptops, video games console, headsets and automobile command console, internet connected television, and so on.
