Problems solved by technology

[0003] In practical applications, it often occurs that one party needs to speak in a low voice in meetings, lectures, etc., and the other party cannot hear clearly because the other party's voice is too low, and the other party is inconvenient to speak loudly. In order to ensure the communication effect, only Manually increase the volume of the mobile phone by yourself. When the call is over, it needs to be adjusted back to the normal volume of the mobile phone, which increases the user's operation
[0004] In addition, when one party is in a noisy environment, the other party may not be able to hear clearly because the received voice signal contains too much noise. In order to ensure the communication effect, the party in the noisy environment can only manually turn on the mobile phone. noise reduction function, which also increases the user's operation

example 1

[0039] As a preferred example 1 of the embodiment of the present invention, the step 203 may include the following sub-steps:

[0040] Sub-step S11, according to the voice signal amplification instruction, amplify the increase of the transmission gain function of the voice signal and execute the amplified transmission gain function.

[0041] When the voice signal amplification instruction is found according to the preset keyword, the voice signal to be transmitted can be amplified by amplifying the gain function of the voice signal transmission of the first user terminal and executing it.

example 2

[0042] As a preferred example 2 of the embodiment of the present invention, the step 203 may include the following sub-steps:

[0043] Sub-step S21, according to the voice signal reduction instruction, reduce the increase of the transmission gain function of the voice signal and execute the transmission gain function after the reduction of the amplification.

[0044] When the voice signal reduction instruction is found according to the preset keyword, the voice signal to be transmitted can be reduced by reducing the gain function of the voice signal sending gain function of the first user terminal and executing it.

example 3

[0045] As a third preferred example of the embodiment of the present invention, the step 203 may include the following sub-steps:

[0046] Sub-step S31, execute the dual-microphone noise reduction function of the first user terminal according to the voice signal noise reduction instruction.

[0047] The microphone noise reduction function can be realized through the dual-microphone noise reduction technology. Two microphones can be built in the user terminal, one is used to stabilize and maintain clear calls, and the other microphone actively eliminates noise signals physically. By collecting external noise signals, certain After processing, the voice signal opposite to the noise signal is output, and the noise signal is eliminated by using the cancellation principle.

[0048] When the voice signal noise reduction instruction is found according to the preset keywords, the dual-microphone noise reduction function can be executed to eliminate the noise signal in the voice signal. ...

Abstract

The embodiment of the invention provides a voice signal processing method, a device and a mobile terminal, and belongs to the technical field of communications. According to the embodiments of the present invention, the method comprises the steps of during the voice communication between a first user terminal and a second user terminal, receiving a voice signal sent from the second user terminal by the first user terminal; recognizing whether the received voice signal contains a keyword or not, and adjusting the to-be-sent voice signal of the first user terminal according to an adjustment instruction corresponding to a preset keyword on the condition that the preset keyword is recognized. According to the embodiment of the invention, the voice signal for influencing the communication effect is automatically adjusted, and the operation of the user is reduced. Therefore, the conversation convenience is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a voice signal processing method, a voice signal processing device, and a voice signal processing mobile terminal. Background technique [0002] With the development of communication technology, more and more people make calls through mobile terminals such as mobile phones and electronic walkie-talkies. [0003] In practical applications, it often occurs that one party needs to speak in a low voice in meetings, lectures, etc., and the other party cannot hear clearly because the other party's voice is too low, and the other party is inconvenient to speak loudly. In order to ensure the communication effect, only Manually turn up the volume of the mobile phone by yourself, and when the call is over, it needs to be adjusted back to the normal volume of the mobile phone, thereby increasing the user's operations. [0004] In addition, when one party is in a noisy ...
