Abstract

Embodiments of the present invention provide a breathing sound detection method and device. The method includes: acquiring an input speech frame, and extracting characteristic parameters of the speech frame; judging whether the speech frame is a cut-off frame of an independent speech segment; parameter, and / or, according to the frame number of the speech frame included in the independent speech segment, it is judged whether the independent speech segment is breathing sound. The technical solution of the invention solves the problem in the prior art that the breathing sound of the participants will reduce the call quality.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a breathing sound detection method and device. Background technique [0002] In a voice conference based on the Internet Protocol (IP for short), each participant needs to wear a headset before talking, and place the microphone at a position corresponding to the mouth according to the feeling. During an actual call, when the participants speak, different call effects will be generated due to the different distances from the microphone to their mouths and / or nostrils. Among them, if the microphone is located below the nostril and close to the nostril, not only when the participant is speaking, but also when the participant is not speaking, the microphone will collect the breathing sound of the participant and transmit it to the other party. This will greatly reduce the call quality of the entire audio conference. Contents of the invention [0003] Embodim...
