Abstract

The monitoring of audio sounds by a Voice Recognition System occasionally detects background noise. Background noise is often interpreted as user input, sometimes even as recognizable user input. This can cause the Voice Recognition System to perform operations due to background noise. Prior art attempts to solve this problem through calibration techniques. This method essentially involves the Voice Recognition System to listen, initially, to a background noise sample. The sample is used as an aggregated factor when the system is actually listening for recognizable phrases.

Interface-Denial through Interrupt-Association

      The monitoring of audio sounds by a Voice Recognition System
occasionally detects background noise.  Background noise is often
interpreted as user input, sometimes even as recognizable user input.
This can cause the Voice Recognition System to perform operations due
to background noise.  Prior art attempts to solve this problem
through calibration techniques.  This method essentially involves the
Voice Recognition System to listen, initially, to a background noise
sample.  The sample is used as an aggregated factor when the system
is actually listening for recognizable phrases.

      A mechanism can be developed that allows a Voice Recognition
System to disregard, automatically, peripheral noise upon activation
of peripheral devices.  An Interrupt Server mechanism monitors user
registered devices.  The associated interrupts for the devices are
monitor with Voice Recognition services.  An Elapse Time Service
measures the amount of elapse time that has occurred between an
interrupt for a device and that of a recognizable phrase.  When the
elapse time is short, e.g., milliseconds, the interrupt server will
disregard the recognizable phrase as a background noise produced by
the peripheral device.

      Optionally, activation/deactivation interrupts can be defined
for the peripheral device.  This option stipulates that the period of
interface is not to be measured in milliseconds, but by reception of
particular interrupts from the device.  This option is advantageous
when the device does not generate a series of interrupts as its mode
of communication.  A printer device easily demonstrates the
significance of the invention.  By using this option the user is
