METHOD AND APPARATUS FOR PRE-PROCESSING AUDIO SIGNALS

摘要

The disclosure is directed to pre-processing audio signals. In one implementation, an electronic device (102) receives an audio signal that has audio information, obtains auxiliary information (such as location, velocity, direction, light, proximity of objects, and temperature), and determines, based on the audio information and the auxiliary information, a type of audio environment in which the electronic device (102) is operating. The device (102) selects an audio pre-processing procedure based on the determined audio environment type and pre-processes the audio signal according to the selected pre-processing procedure. The device (102) may then perform speech recognition on the pre-processed audio signal.
