Abstract

The application discloses a call signal processing method, device, electronic equipment and storage medium, and relates to the field of voice technology. The specific implementation plan is: according to at least two preset thresholds and statistics constructed based on the call signal, detect the current call state; obtain the gain factor corresponding to the call state; use the gain factor corresponding to the call state to the The call signal is processed. The present application adopts the above-mentioned technical solution, which can accurately detect the call state, and effectively process the residual signal, avoid discontinuity and stuttering of the processed voice, and effectively improve the processing efficiency of the call signal.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of voice technology, and in particular to a method, device, electronic equipment and storage medium for processing call signals. Background technique [0002] With the rapid development of the Internet, IP-based voice transmission (voice over internet protocol; voip) has become one of the indispensable needs of people. For example, various remote conference calls use related technologies. [0003] In the existing voip communication, the echo problem existing in the hands-free communication greatly reduces the experience of both communication parties, where the echo is generated by the coupling between the loudspeaker and the microphone. For example, the voice of communication party A is collected by the microphone and then transmitted to communication party B through the network, and played out through the speaker of communication party B, and the played sou...
