Abstract
Present disclosure disclose a voice signal processing method, includes: receiving a first voice coded signal from a first terminal; performing voice decoding processing on the first voice coded signal to obtain a voice decoding parameter and a first voice decoded signal; performing, by using the voice decoding parameter, virtual bandwidth extension processing to obtain a bandwidth extension voice decoded signal corresponding to the first voice decoded signal; after combining the first voice decoded signal and the bandwidth extension voice decoded signal, performing voice coding processing to obtain a second voice coded signal; and sending the second voice coded signal to a second terminal that establishes a call connection to the first terminal, where a maximum frequency bandwidth supported by the first terminal is less than a maximum frequency bandwidth supported by the second terminal. Thus, Service quality of terminals that have asymmetric maximum frequency bandwidth support capabilities can be improved.
