Abstract

The present application proposes an adaptive call volume control method, comprising the following steps: respectively collecting far-end voice signals and near-end voice signals, and extracting and forming far-end subband signals and near-terminal band signals through filtering; The near-terminal band signal forms the voice equalization parameters for the far-end voice signal and the near-end voice signal; according to the voice equalization parameters, the far-end sub-band signal is multiplied by gain, and the output sub-band signal obtained by decoding is obtained; the decoding is played through the speaker The output speech of the subband signal is output. The present application also correspondingly proposes an adaptive call volume control device. The beneficial effects of the present application are: on the basis of comprehensively considering the auditory characteristics of the human ear and the influence of environmental noise, the effect of improving the call quality is achieved through the adjustment in the subjective perception domain.

Description

technical field [0001] The invention relates to the field of speech signal processing, in particular to an adaptive call volume control method and device during a call. Background technique [0002] With the development of mobile networks and the portability and mobility of consumer electronics, people's communication methods are becoming more and more diverse. As the most basic communication method, voice communication has become available everywhere, and the environment and scenarios of voice communication are becoming more and more complex. People can make voice calls anywhere in their homes, offices, subway stations, factories, etc. A typical problem faced by these complex usage scenarios is the problem of noise. [0003] Today's communication equipment generally takes these noise issues into consideration. Generally, related communication devices more or less include noise reduction technology for noise suppression or elimination. This enables the far end to hear th...
