Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating a call quality control method according to an exemplary embodiment, where the call quality control method is applied to a mobile terminal, for example, a terminal such as a mobile phone that can be used for voice call or video call. The embodiment relates to a specific process that the mobile terminal determines the gain of a microphone according with the current environment type according to the current environment type, so that the mobile terminal reasonably amplifies a voice signal collected by the microphone. As shown in fig. 1, the method comprises the steps of:
in step S101, an environment type of an environment in which the terminal is currently located is acquired.
In this step, the mobile terminal obtains the environment type of the current environment, which may be obtained before entering the call process or after entering the call process, and optionally, the environment type of the environment where the mobile terminal obtains after entering the call process may be obtained when the mobile terminal enters the call waiting state after the dialing is completed. Optionally, the environment type of the current environment acquired by the mobile terminal may include a noisy environment, a quiet environment, and a sound environment between the noisy environment and the quiet environment, where the noisy environment may be an indoor noisy environment or an outdoor noisy environment, and the quiet environment may be an indoor quiet environment or an outdoor quiet environment.
In step S102, determining a gain of a microphone corresponding to the environment type according to the environment type and a preset mapping relationship; the mapping includes a correspondence of different environmental types to different microphone gains.
In this step, after the mobile terminal obtains the environment type of the current environment, a mapping relation preset inside the mobile terminal is queried according to the environment type to determine the gain of the microphone corresponding to the environment type. It should be noted that the gain of the microphone according to the embodiments of the present disclosure may be an amplification factor or an amplification capability for amplifying the voice signal of the user collected by the microphone. Optionally, when the environment type of the current environment determined by the mobile terminal is an outdoor noisy environment, the gain of the microphone corresponding to the environment type is relatively large, and optionally, when the environment type of the current environment determined by the mobile terminal is an indoor noisy environment, the gain of the microphone corresponding to the environment type may be smaller than the gain of the microphone corresponding to the outdoor noisy environment, but needs to be larger than the gain of the microphone corresponding to the indoor or outdoor quiet environment. Through confirming the gain with the microphone of current environment type adaptation, can make the microphone carry out reasonable amplification to the speech signal who gathers at present to avoid appearing excessively amplifying speech signal and lead to the sound distortion that the opposite terminal heard, also avoid appearing speech signal and amplify the condition emergence that the degree is not enough to lead to the opposite terminal to hear unclear sound. The fixed microphone gain set in the mobile terminal cannot amplify the voice signals collected in different environment types to different degrees, so that the situation of sound distortion or inaudible sound of the opposite terminal is easy to occur, and compared with the microphone gain set fixedly, the technical scheme of the embodiment can ensure the call quality between the local terminal and the opposite terminal.
Optionally, the mapping relationship may be directly loaded into the mobile terminal by a manufacturer of the mobile terminal through a software loading fixture on a production line when the manufacturer produces the mobile terminal, or may be obtained by a user of the mobile terminal downloading a software package from a corresponding website through a network downloading function, and the obtaining manner of the mapping relationship is not limited in this embodiment.
In step S103, the speech signal collected by the microphone is amplified according to the gain of the microphone corresponding to the environment type.
Optionally, the voice signal may be a voice signal input by a user, or may also be a voice signal input by the user to another external device, and the voice signal input to the mobile terminal through the external device is, for example, input to the mobile terminal through an earphone. After the mobile terminal determines the gain of the microphone corresponding to the environment type according to the environment type, the voice signal collected by the microphone is amplified according to the gain, the amplified voice signal is transmitted to a baseband part inside the mobile terminal, and subsequent digital-to-analog conversion and other processing are carried out to send the voice signal to the opposite terminal, so that the opposite terminal can hear the voice with higher quality, and the communication quality is improved.
According to the call quality control method provided by the embodiment, the mobile terminal acquires the environment type of the current environment, and determines the gain of the microphone corresponding to the environment type according to the environment type and the preset mapping relation, so that the voice signal collected by the microphone is amplified according to the gain of the microphone, the microphone can reasonably amplify the current collected voice signal, the sound distortion heard by an opposite terminal due to the fact that the voice signal is excessively amplified is avoided, the situation that the opposite terminal cannot hear sound due to the fact that the amplification degree of the voice signal is insufficient is also avoided, and the call quality when the local terminal calls with the opposite terminal is improved.
Fig. 2 is a flowchart illustrating a call quality control method according to another exemplary embodiment, which is applied to a mobile terminal, for example, a terminal such as a mobile phone that can be used for voice call or video call. The embodiment relates to a specific process for acquiring the environment type of the current environment by the mobile terminal. On the basis of the foregoing embodiment, further, the foregoing S101 may include the following steps:
in step S201, environmental factors of the current environment of the terminal are collected, where the environmental factors include at least one of the following factors: sound information of the current environment of the terminal and position information of the current environment of the terminal.
In step S202, the environment type is determined according to the environmental factors of the environment in which the terminal is currently located.
In this embodiment, when the mobile terminal needs to communicate with the opposite terminal, the mobile terminal may collect an environmental factor of a current environment, optionally, the environmental factor may include at least one of sound information of the current environment of the mobile terminal and location information of the current environment of the mobile terminal, and optionally, the sound information may be a decibel value of background noise of the environment.
After the mobile terminal determines the environmental factors of the current environment, the environmental type of the current environment of the mobile terminal can be determined according to the environmental factors and the corresponding relationship between different environmental types defined for different environmental factors in the mobile terminal. Optionally, the corresponding relationship may be a corresponding relationship between different sound decibel ranges and different environment types, a corresponding relationship between different position information and different environment types, or a corresponding relationship between different sound decibel ranges, different position information, and different environment types.
For example, when the environmental factor determined by the mobile terminal is that the background noise decibel value of the current environment is 79dB, the current location information is located indoors, and in the corresponding relationship between different environmental types defined for different environmental factors inside the mobile terminal, the sound decibel range of 70dB to 80dB and the environmental type corresponding to the indoor environment are indoor noisy environments, the mobile terminal determines that the environmental type where the mobile terminal is currently located is an indoor noisy environment, and then the mobile terminal can determine the gain of the microphone corresponding to the indoor noisy environment according to the mapping relationship.
According to the control method of the call quality, the environmental factors of the current environment of the mobile terminal are collected, and the environmental type of the current environment of the mobile terminal is determined according to the environmental factors, so that the environmental type determined by the mobile terminal is more fit with the actual environment, the gain of the microphone determined by the mobile terminal is more accurate, and the call quality is further improved.
Fig. 3 is a flowchart illustrating a call quality control method according to yet another exemplary embodiment, where the call quality control method is applied to a mobile terminal, for example, a terminal such as a mobile phone that can be used for voice call or video call. The embodiment relates to a specific process for acquiring a mapping relation by a mobile terminal through early test data. On the basis of the foregoing embodiment, further, before the foregoing S101, the method may further include the following step:
in step S301, test data including a correspondence between different environment types, different microphone gains, and different call qualities is acquired.
In this step, before the mobile terminal leaves the factory, research and development personnel can test the call quality of the mobile terminal to obtain test data. The method specifically comprises the following steps: research personnel set different microphone gains for the microphone inside the mobile terminal to initiate a call request to the opposite terminal under different environment types, and collect the call quality of the opposite terminal, so that the call quality corresponding to the different microphone gains under each environment type can be obtained.
In step S302, the mapping relationship is constructed according to the test data and a preset rule.
In this step, after the mobile terminal obtains the test data, the mobile terminal may construct the mapping relationship according to a preset rule, where the preset rule may be an evaluation criterion of the call quality, and under the same environment type, the mobile terminal may determine, according to the best call quality corresponding to the environment type, a gain of a microphone corresponding to the best call quality, and further establish a corresponding relationship between the environment type and the gain of the microphone, and so on, to obtain the mapping relationship.
The mapping relation in the embodiment is obtained according to actual test data, so that the gains of the microphones corresponding to different environment types are more reasonable and effective, and the call quality between the local terminal and the opposite terminal can be better ensured.
Optionally, the mobile terminal may obtain the mapping relationship, or obtain the mapping relationship from a network server, for example, the mobile terminal may send an obtaining request of the mapping relationship to the network server (the obtaining request may carry an identifier of the mobile terminal), and the network server sends the mapping relationship to the mobile terminal according to the identifier of the mobile terminal in the obtaining request. Optionally, the mapping relationship in the network server may be that after a developer of the mobile terminal constructs the mapping relationship through the test data and the corresponding preset rule, the mapping relationship is uploaded to the network server by using a unified upload platform, so that the mapping relationship may face all mobile terminals through the network server, or face a certain type of mobile terminal, and then the mobile terminal may download the mapping relationship from the network server. Further, on the basis of this embodiment, the method may further include the following steps:
in step S301, when a new environmental factor is collected, the new environmental factor is transmitted to the web server.
In this step, when the mobile terminal collects the environmental factors of the current environment of the mobile terminal, it is assumed that the mobile terminal does not collect the sound information of the current environment or the position information of the current environment because of the relationship of hardware or software, however, the mobile terminal collects the factor of the moving speed of the mobile terminal, and therefore, the mobile terminal may attempt to determine the type of environment in which the mobile terminal is currently located according to the factor, however, because the current mapping relationship of the mobile terminal does not have the corresponding relationship between the moving speed and the environment type, the mobile terminal cannot know the current environment type of the mobile terminal, so that the mobile terminal cannot obtain the proper microphone gain during the call, optionally, the mobile terminal amplifies the voice signal collected this time by an intermediate value of the gain of one microphone. And the mobile terminal sends the new environmental factor to the network server, so that the network server knows that the mapping relationship downloaded by the current mobile terminal cannot meet the requirements of the user, and then the network server can inform research and development personnel of the mobile terminal to update the mapping relationship through the uploading platform, i.e. a new environmental type is defined for the new environmental factor and corresponds to the gain of a new microphone, so that the mapping relationship on the network server can be updated, and then the network server can send the updated mapping relationship to the mobile terminal in time, thereby further ensuring the call quality between the local terminal and the opposite terminal.
The mapping relationship in the embodiment is obtained through the network server, and it can be ensured that when the mobile terminal detects a new environmental factor, the new environmental factor can be reported to the network server, so that the network server can timely notify research and development personnel to update the mapping relationship on the network server, and then send the updated mapping relationship to the mobile terminal, so that the gain of the microphone determined by the mobile terminal is more reasonable and effective, and the communication quality between the local terminal and the opposite terminal is more ensured.
