SYSTEMS AND METHODS OF BLIND BANDWIDTH EXTENSION

摘要

Systems and methods of performing blind bandwidth extension are disclosed. In an embodiment, a method includes receiving, at a decoder of a speech vocoder, a set of low-band parameters as part of a narrowband bitstream. The set of low-band parameters are received from an encoder of the speech vocoder. The method also includes predicting a set of high-band parameters based on the set of low-band parameters.
