Claim Text:
1. A method for producing enhanced speech data associated with at least one speaker, said method comprising: a) receiving distant signal data from at least one distant acoustic sensor; b) receiving proximate signal data from at least one other proximate acoustic sensor located closer to said speaker than said at least one distant acoustic sensor; c) receiving optical data originating from at least one optical unit configured for optically detecting acoustic signals in an area of said speaker and outputting data associated with speech of said speaker; d) processing said distant signal data and said proximate signal data for producing a speech reference and a noise reference; e) 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 f) 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.
