Abstract

The invention discloses a method and device capable of improving voice clarity and a medium. The method comprises the following steps: acquiring a first sound signal acquired by a first sound acquisition device and acquiring a second sound signal acquired by a second sound acquisition device; judging whether the amplitude of the differential signal is smaller than a first preset amplitude or not;and when the amplitude of the differential signal of the first sound signal and the second sound signal is smaller than a first preset amplitude, performing weighted differential processing on the first sound signal and the second sound signal to obtain a third sound signal. According to the method, the differential signal of the first sound signal and the second sound signal is used as a signal after preliminary denoising, whether the signal after preliminary denoising satisfies a sound clarity condition is detected in real time, and the signal after preliminary denoising is directly used when the signal after preliminary denoising satisfies the sound clarity condition; and if not, the first sound signal and the second sound signal are further subjected to weighted difference processing,so that the sound clarity is improved in time, and the call quality and the user experience are improved.

Description

technical field [0001] This article relates to the technical field of mobile terminal data processing, and in particular to a method, device and medium for improving voice clarity. Background technique [0002] With the continuous improvement of the hardware performance and software performance of the mobile terminal, the quality of service that the mobile terminal can provide is getting better and better. In order to better process the sound, the mobile terminal contains two sound collection devices, such as figure 1 In the schematic diagram of the mobile terminal shown, a main microphone is set at a position below the front of the mobile terminal, and a secondary microphone is set at a position above the front of the mobile terminal. When the mobile terminal is in normal use, because the main microphone is closer to the user's mouth, the amplitude of the voice signal in the sound signal collected by the main microphone is greater than that of the sound signal collected by...
