Controlling mobile device based on sound identification
First Claim
1. A method for performing an operation at a mobile device, the method comprising:
- capturing a sound from a sound output device external to the mobile device;
determining confidence values for a plurality of basis filters;
selecting at least one basis filter of the plurality of basis filters based on the confidence values;
processing, based on the at least one basis filter, data representing the sound to extract a sound feature from the data, the sound feature associated with the sound; and
performing the operation of the mobile device responsive to the sound feature.

Abstract
A method and apparatus for performing a function in a mobile device are disclosed. A media sound from a sound output device external to the mobile device is captured and a sound feature is extracted from the captured media sound. A function to be performed in the mobile device is determined by identifying at least one reference sound feature in a set of reference sound features based on the extracted sound feature, each reference sound feature in the set of reference sound features being associated with at least one of a plurality of media sounds and at least one of a plurality of functions. Further, the determined function is performed in the mobile device.

14. A method for performing an operation at a mobile device, the method comprising:
-
capturing, by a plurality of sound sensors, a composite sound including at least one media sound; determining confidence values for a plurality of basis filters; selecting at least one basis filter of the plurality of basis filters based on the confidence values; processing, based on the at least one basis filter, data representing the composite sound to extract sound data representing the at least one media sound from the data representing the composite sound and to extract at least one sound feature from the sound data representing the at least one media sound; and performing the operation of the mobile device responsive to the at least one sound feature. - View Dependent Claims (15, 16, 17, 18)
