Embodiment 1

[0041] According to an embodiment of the present invention, a noise reduction method is provided, figure 1 It shows a schematic flow chart of a noise reduction method proposed in Embodiment 1 of the present invention, as shown in figure 1 As shown, the noise reduction method may include: Step 110 to Step 130 .

[0042] In step 110, the calling scene where the terminal is located is determined.

[0043] Here, the call scene where the terminal is located refers to the scene where the terminal is when establishing a call. For example, if the user establishes a call at a station, the call scene of the terminal is the station; if the user establishes a call at the mall, the call scene of the terminal is the mall.

[0044] In step 120, according to the call scene, a noise reduction model matching the type of the call scene is obtained from a preset database.

[0045] Here, by acquiring the noise reduction model that matches the type of the call scene, when the user establishes a ...

Embodiment 2

[0051] On the basis of the foregoing embodiments, Embodiment 2 of the present invention may further provide a noise reduction method. figure 2 It shows a schematic flow chart of a noise reduction method proposed in Embodiment 2 of the present invention, as shown in figure 2 As shown, the noise reduction method may include: Step 210 to Step 240.

[0052] In step 210, the ambient noise of the environment where the terminal is located is acquired.

[0053] Here, acquiring the environmental noise of the environment where the terminal is located can be collected by a voice collection device installed on the terminal, such as an earpiece. Wherein, the process of acquiring the ambient noise of the environment where the terminal is located is performed after the user is about to establish a call or successfully establishes a call.

[0054] In step 220, the call scene where the terminal is located is determined according to the environmental noise.

[0055]Here, specific scenes w...

Embodiment 3

[0079] On the basis of the foregoing embodiments, Embodiment 3 of the present invention may further provide a noise reduction method. Figure 4 It shows a schematic flow chart of a noise reduction method proposed in Embodiment 3 of the present invention, as shown in Figure 4 As shown, the noise reduction method may include: Step 310 to Step 350.

[0080] In step 310, voice information is acquired.

[0081] Here, the voice information may be a voice control command input by the user. For example, when a user is at a station, he can input a voice control command before making a call to obtain a corresponding noise reduction model.

[0082] In step 320, semantic analysis is carried out to described speech information, to obtain the key word that reflects conversation scene.

[0083] In step 330, the calling scene where the terminal is located is determined according to the keyword.

[0084] Here, performing semantic analysis on the voice information includes extracting keyw...

Abstract

The invention discloses a noise reduction method and system, a storage medium and a terminal, and relates to the technical field of voice noise reduction, and the method comprises the steps: determining a call scene where the terminal is located; obtaining a noise reduction model matched with the type of the call scene from a preset database according to the call scene; and performing noise reduction processing on the voice signal sent and/or received by the terminal by using the noise reduction model. The beneficial effects of the invention are that: the corresponding noise reduction processing can be carried out according to different call scenes, and the uplink voice and/or the downlink voice can be respectively subjected to noise reduction, so that the user of the terminal is not influenced by the external noise during the call, the voice information received by the opposite terminal is clear and has no noise, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of voice noise reduction, in particular to a noise reduction method, system, storage medium and terminal. Background technique [0002] At present, the mobile phones on the market are basically equipped with a set of noise reduction parameters optimized for various scenarios. However, in complex noise scenarios, this general-purpose mode cannot be fully compatible with various complex noise scenarios, so users can only improve the call experience by turning up the volume of the mobile phone. This makes in some special noise scenes, brings bad user experience to the user's voice call. Contents of the invention [0003] Based on the above technical problems, the present invention proposes a noise reduction method, system, storage medium and terminal capable of determining a matching noise reduction model according to the call scene where the terminal is located, so as to improve user experience. ...
