First Claim
Patent Images
1. A method of performing microphone beamforming, the method comprising:
- distinguishing at least a portion of received sound as speech by a speaker from noise;
identifying the speaker by comparing the received speech with previously stored speech in a data storage to obtain an identification of the speaker;
based on the identification of the speaker, searching images stored in the data storage for a stored image associated with the identified speaker;
searching for a position of the identified speaker through a camera by comparing the stored image of the identified speaker with image data received through the camera;
recognizing the position of the identified speaker; and
performing microphone beamforming according to the position of the identified speaker.

15. A non-transitory computer-readable recording medium encoded with computer-executable instructions that when executed cause a data processing system to:
-
distinguish at least a portion of received sound as speech by a speaker from noise; identify the speaker by comparing the received speech with previously stored speech in a data storage to obtain an identification of the speaker; based on the identification of the speaker, search images stored in a data storage for a stored image associated with the identified speaker; search for a position of the identified speaker through a camera by comparing the stored image of the identified speaker with image data received through the camera; recognize the position of the identified speaker; and perform microphone beamforming according to the position of the identified speaker. - View Dependent Claims (16, 17, 18, 19, 20)
