Method and system for noise reduction and speech enhancement

A system producing enhanced speech data associated with at least one speaker, said system comprising:

• a) at least one distant acoustic sensor outputting distant signal data;
• b) at least one proximate acoustic sensor located closer to said speaker than said at least one distant acoustic sensor, said proximate acoustic sensor outputs proximate signal data;
• c) at least one optical unit configured for optically detecting acoustic signals in an area of said speaker and outputting optical data associated therewith;
• and
• d) at least one processor operating modules configured for:
• receiving proximate data, distant data and optical data from the acoustic and optical sensors;
• processing said distant signal data and said proximate signal data for producing a speech reference and a noise reference of the time domain;
• operating an adaptive noise estimation module configured for identifying stationary and/or transient noise signal components, said adaptive noise estimation module uses said noise reference;
• and operating a post filtering module, which uses said optical data, speech reference and the identified noise signal components from said adaptive noise estimation module for creating an enhanced speech reference data and outputting thereof.
