Patent ID: 8781818

Claim:
A speech capturing device-comprising: a capturing circuit, wherein the capturing circuit includes a plurality of microphones for capturing a plurality of sound signals originating from different spatial locations; one or more extracting circuits each for deriving a respective speech signal corresponding to a respective speaker from the plurality of the sound signals; a residual extracting circuit for deriving one or more ambient signals from the plurality of sound signals each decreased by the one or more speech signals derived by the one or more extracting circuits; and a transmitting circuit for transmitting the one or more speech signals and the one or more ambient signals, further comprising: an audiovisual locator for (i) determining one or more locations of the speakers and (ii) providing one or more output signals of spatial information about the locations of the speakers to the one or more extracting circuits, respectively, wherein each extracting circuit derives the respective speech signal further in response to a respective output signal of spatial information directed to a location of a respective one of the speakers.
