1. A network call method, applicable to a computer device, the method comprising:
performing time-frequency transformation on an acquired audio signal to obtain a plurality of pieces of frequency domain information of the audio signal;
prior to encoding the audio signal, inputting the plurality of pieces of frequency domain information into a bit rate prediction model to obtain a plurality of first candidate bit rates, the plurality of first candidate bit rates being sufficient to meet a target speech quality condition, the bit rate prediction model being pre-trained based on training audio data of different coding quality requirements;
determining a first bit rate that meets a target condition from the plurality of first candidate bit rates as a target bit rate;
encoding the audio signal based on the target bit rate; and
performing a network call based on the encoded audio signal.
