Voice signal processing method and device, and electronic equipment

Abstract

The embodiment of the invention relates to the technical field of voice signal processing, and provides a voice signal processing method and device, and electronic equipment. The method is applied toa controller of the electronic equipment, and the electronic equipment comprises a first microphone and a first loudspeaker arranged indoors, and a second microphone and a second loudspeaker arrangedoutdoors. The method comprises the following steps: judging whether the electronic equipment is in communication connection with terminal equipment or not; if the electronic equipment is not in communication connection with the terminal equipment, carrying out echo elimination processing and whistle elimination processing on acquired voice signals that are sent from the first microphone and the second microphone; and sending voice signals that are obtained through the echo elimination processing and the whistle elimination processing to the first loudspeaker and the second loudspeaker for voice playing. Through the method, a corresponding voice signal processing mode can be selected based on whether the electronic equipment is in communication connection with the terminal equipment or not, and the echo elimination processing and the whistle elimination processing can be simultaneously carried out when the electronic equipment is not in communication connection with the terminal equipment, so that the voice signal processing efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of sound signal processing, in particular to a sound signal processing method, a sound signal processing device and electronic equipment. Background technique [0002] In the process of sound transmission, some acoustic paths will continue to attenuate and disappear with the number of transmissions. The shorter delay between the feedback signal and the direct signal is called reverberation, the longer one is called echo, and some acoustic paths It will continue to increase with the increase of the number of transmissions, and finally make a very harsh sound directly. This phenomenon is called howling. However, the inventor found that in the prior art, there is no method that can select the corresponding sound signal processing method according to whether there is a terminal device connected to the communication and simultaneously process the echo and howling in the same sound field, so there is a Th...
