1. An apparatus comprising:
a classifier to determine an audio characteristic value representative of an audio characteristic in audio;
a transition detector to detect a transition between a first category and a second category by comparing the audio characteristic value to a threshold value among a set of threshold values, the set of threshold values corresponding to the first category and the second category; and
a context manager to control a device to reduce a rate of audio classification requests responsive to the detected transition between the first category and the second category.
