Mounting Microphone Arrays on Computer and Television Displays

      Disclosed is the attachment of several microphones to the front
and/or sides of a computer or television display.

      The Figure is a front elevational view of a preferable
configuration, in which microphones 1 are attached around a display
screen 2 in upper left, upper right, and lower center positions.
Alternately, microphones may be attached similarly around the flat
screen of a laptop computer or around a horizontal flat screen lying
along the top surface of a desk.  Signals from the microphones are
provided as inputs to Analog to Digital Converter (ADC) circuits,
which in turn provide inputs to a Digital Signal Processor (DSP), to
a microprocessor, or to a coprocessor for noise cancellation.  A
resulting signal is then passed to a speech recognition system, a
voice annotation system, a natural language processing application,
or another type of application program.

      This arrangement provides an envelope of speech recognition, in
which words spoken by the user can be recognized, extending outward
from the display screen 2.  The limits of the envelope can also be
used to eliminate noise from other sources, such as a computer
keyboard, a telephone, a door, and an air conditioning vent, which
may interfere with the speech recognition process.

      In the simplest configuration, separate controls are not
provided for varying the characteristics of the speech recognition
