Embodiment 1

[0043] figure 1 A flow chart of the method for optimizing call sound provided by this embodiment is shown. The method can be executed on a mobile terminal, and the mobile terminal can be a device at the calling end or a device at the called end. Such as figure 1 As shown, the method includes the following steps:

[0044] Step S101, performing noise reduction processing on the current call sound to obtain denoised voice;

[0045] The noise reduction processing in this step is mainly used to filter out the noise in the surrounding environment of the local caller or the caller at the opposite end of the call.

[0046] Step S102, acquiring the sound quality clarity value of the denoised speech, which is a parameter to measure the clarity of the denoised speech;

[0047] Considering that the noise reduction processing of the call sound in step S101 is usually to filter out the environmental noise, which cannot alleviate the unclear call sound caused by human factors, in order t...

Embodiment 2

[0071] In this embodiment, two common factors in unclear sound quality caused by human factors are mainly considered: one is dialect, and the other is unclear articulation. However, the sound quality values ​​corresponding to these two factors have significantly different interval ranges. Based on this, this embodiment provides the following image 3 The optimization method of the shown call sound, the method may further comprise the steps:

[0072] Step S301, performing noise reduction processing on the current call sound to obtain denoised voice;

[0073] Step S302, obtain the sound quality clarity value of the denoised speech, the sound quality clarity value is a parameter to measure the clarity of the denoised speech, the specific content is the same as the description in the above embodiment, and will not be repeated here;

[0074] Step S303, judging whether the sound quality clarity value is lower than the set first clarity threshold; if yes, execute step S304; if not, ...

Embodiment 3

[0087] Considering the diversification of user needs, this embodiment also provides control buttons or options for the user to select the sound quality enhancement function, and the user can choose to turn on or off the sound quality enhancement function according to needs. If the sound quality enhancement function is in an open state, the method for optimizing the call sound in Embodiment 1 or Embodiment 2 can be performed; if the sound quality enhancement function is in a closed state, the current call sound can be directly output according to related technologies, or only The current call tone is output after the above-mentioned noise reduction processing is performed.

[0088] see Figure 4 The specific flow chart of the optimization method of the shown call sound, the method comprises the following steps:

[0089] Step S401, when the current call tone is received, judge whether the set sound quality enhancement function is enabled; if yes, execute step S402, if not, exec...

Abstract

The embodiments of the invention provide a conversation voice optimizing method, apparatus and conversation terminal, and relates to the technical field of conversation voice. The method herein includes: de-noising of a current conversation voice to obtain a de-noised voice; acquiring a voice clarity value of the de-noised voice, the voice clarity value referring to a parameter which measures the clarity of a de-noised voice; when the voice clarity value is lower than a set clarity threshold, correcting the de-noised voice; and outputting the de-noised voice which is subject to the correction. Compared with prior art, according to the embodiments of the invention, the method, the apparatus and the conversation terminal, by de-noising the current conversation voice and correcting the de-noised voice which is subject to the de-noising if the voice clarity value is too low, mitigate poor conversation quality caused by man-made factors, increase the quality of the conversation voice, and improve user experience of the conversation participants.

Description

technical field [0001] The present invention relates to the technical field of call voice, in particular, to a call sound optimization method, device and call terminal. Background technique [0002] At present, when users use mobile phones, telephones and other communication devices for remote communication, the communication effect is often affected by poor communication quality. There are many factors that cause poor call quality, including cell base station problems, terminal antenna quality problems, and human factors. The problem of poor call quality caused by equipment factors such as cell base stations or terminal antennas can be alleviated through hardware maintenance and debugging by operators or manufacturers. However, human factors are difficult to change, especially the poor call quality caused by the caller's unclear articulation and poor sound quality. At present, there is still no effective solution. Contents of the invention [0003] In view of this, the ...
