METHOD AND DEVICE FOR SPEECH/MUSIC CLASSIFICATION AND CORE ENCODER SELECTION IN A SOUND CODEC

摘要

Two-stage speech/music classification device and method classify an input sound signal and select a core encoder for encoding the sound signal. A first stage classifies the input sound signal into one of a number of final classes. A second stage extracts high-level features of the input sound signal and selects the core encoder for encoding the input sound signal in response to the extracted high-level features and the final class selected in the first stage.
