METHOD AND SYSTEM FOR BANDWIDTH EXPANSION FOR VOICE COMMUNICATIONS
摘要
The invention concerns a method (400) and system (100) for bandwidth extension of voice for improving the quality of voice in a communication system. The method can include the steps of receiving (412) an unknown voice signal (105), identifying (414) the voice bandwidth (625) of the received unknown voice signal and establishing (418) a region of support (636) in view of the spectral content of the received voice signal. The method can further include the step of selecting (428) a combination of mapping databases (210, 212, 214) from a plurality of mapping databases. Each mapping database can be associated with a predetermined bandwidth extension range for extending the voice bandwidth.
