Abstract

The embodiment of the present application discloses a call noise reduction method, device, and terminal, which belong to the technical field of voice calls. The method includes: in the call state, acquiring the working state of the terminal, and the working state includes an unfolded state and a folded state; According to the working state, the respective working modes of at least two microphones are set, and the working modes include a radio mode and a noise reduction mode; the first audio signal is collected by the microphone in the noise reduction mode, and the second audio signal is collected by the microphone in the radio mode; Perform noise reduction processing on the second audio signal according to the first audio signal. The embodiment of the present application realizes the self-adaptive setting of the positions of the sound receiving microphone and the noise reduction microphone, so as to ensure better call quality under different working conditions.

Description

technical field [0001] The embodiments of the present application relate to the technical field of voice calls, and in particular, to a method, device, and terminal for noise reduction in calls. Background technique [0002] With the continuous maturity and development of the display screen manufacturing process, a terminal with a foldable display screen emerges as the times require. [0003] A terminal with a folding display includes an unfolded state and a folded state. In the folded state, the folding display is U-shaped; while in the unfolded state, the folding display is V-shaped or flat. And in order to improve call efficiency, when the folding display screen is in the unfolded state or the folded state, the user can use the terminal to make a call. Contents of the invention [0004] The embodiment of the present application provides a call noise reduction method, device, and terminal, which can be used to solve the problem of poor call quality caused by changes in...
