Speech transmission method, system and apparatus, computer-readable storage medium, and device

An audio transmission apparatus, comprising:

• processing circuitry configured to
• receive current encoded data of an audio signal;
• determine a packet loss recovery capability corresponding to the current encoded data according to a first audio encoding feature parameter corresponding to the current encoded data and a second audio encoding feature parameter corresponding to previous or subsequent encoded data of the current encoded data using a packet loss recovery capability prediction neural network model, the packet loss recovery capability corresponding to a quality loss of a decoded audio when the current encoded data is lost while being transmitted over a network;
• determine whether to perform redundant encoding for the current encoded data according to the packet loss recovery capability;
• and
• in response to the redundant encoding being determined to be performed, performing the redundant encoding according to the current encoded data to generate a corresponding redundancy packet.

A non-transitory computer-readable storage medium storing instructions which when executed by at least one processor cause the at least one processor to perform:

• receiving current encoded data of an audio signal;
• determining a packet loss recovery capability corresponding to the current encoded data according to a first audio encoding feature parameter corresponding to the current encoded data and a second audio encoding feature parameter corresponding to previous or subsequent encoded data of the current encoded data using a packet loss recovery capability prediction neural network model, the packet loss recovery capability corresponding to a quality loss of a decoded audio when the current encoded data is lost while being transmitted over a network;
• determining whether to perform redundant encoding for the current encoded data according to the packet loss recovery capability;
• and
• in response to the redundant encoding being determined to be performed, performing the redundant encoding according to the current encoded data to generate a corresponding redundancy packet.
