Abstract: A server system includes a cloud application program, a system framework, a forwarding program, and an audio capturing program. The server system inputs first audio data of the cloud application program to the system framework, processes the first audio data through the system framework to obtain second audio data, and transmits the second audio data to the forwarding program. The second audio data is then transmitted from the forwarding program to the audio capturing program according to a communication connection between the forwarding program and the audio capturing program. The audio capturing program transmits the second audio data to a local application program of a terminal. Because the second audio data obtained after processing through the system framework is directly sent to the audio capturing program through the forwarding program, a transmission link of audio data is shortened, thus reducing the delay in delivering audio data.
