Title:
VOICE SIGNAL PROCESSING METHOD, AND RELATED DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/206432
Kind Code:
A1
Abstract:
A voice signal processing method, and a related device and system. The voice signal processing method comprises: a network device receiving a first voice encoded signal from a first terminal (201); performing voice decoding processing on the first voice encoded signal to obtain voice decoding parameters and a first voice decoded signal (202); performing virtual bandwidth extension processing by using the voice decoding parameters to obtain a bandwidth-extended voice decoded signal corresponding to the first voice decoded signal (203); combining the first voice decoded signal and the bandwidth-extended voice decoded signal and then performing voice encoding processing to obtain a second voice encoded signal (204); sending the second voice encoded signal to a second terminal that establishes a call connection with the first terminal (205), the maximum bandwidth supported by the first terminal being smaller than the maximum bandwidth supported by the second terminal. The present invention facilitates improvement of the service quality when the maximum bandwidth supporting capabilities of terminals are asymmetric.
