ADAPTIVE AUDIO FRAME PROCESSING FOR KEYWORD DETECTION

摘要

A method of detecting a target keyword from an input sound for activating a function in a mobile device is disclosed. In this method, a first plurality of sound features is received in a buffer, and a second plurality of sound features is received in the buffer. While receiving each of the second plurality of sound features in the buffer, a first number of the sound features are processed from the buffer. The first number of the sound features includes two or more sound features. Further, the method may include determining a keyword score for each of the processed sound features and detecting the input sound as the target keyword if at least one of the keyword scores is greater than a threshold score.
