示例性的，本发明实施例中的终端可包括手机、平板电脑、音乐播放器以及录音笔等配置有麦克风的设备。麦克风可以是内置的，也可以是外置的。麦克风(简称mic，又称传声器或话筒)是一种将声音信号转换为电信号的能量转换器件，当声音的振动传到麦克风的振动膜上后，会导致里面的磁铁形成变化的电流信号，由声音处理电路对电流信号进行处理后传输到通话对端或进行存储，进而实现通话或录音。本发明实施例对麦克风的具体类型、数量及所在位置不做限定，例如，对于手机来说，可以是设置在手机下侧面的一个或多个驻极体式麦克风。Exemplarily, the terminal in this embodiment of the present invention may include a mobile phone, a tablet computer, a music player, a voice recorder, and other devices equipped with a microphone. Microphones can be built-in or external. Microphone (referred to as mic, also known as microphone or microphone) is an energy conversion device that converts sound signals into electrical signals.

为了便于理解本发明实施例，下面以智能手机为例对音频处理硬件系统及系统架构进行简单的介绍。In order to facilitate understanding of the embodiments of the present invention, the following briefly introduces an audio processing hardware system and a system architecture by taking a smartphone as an example.
图2为本发明实施例提供的一种智能手机的音频处理硬件系统结构示意图。音频处理电路一般处于主控电路板中，由于不同手机的设计不同，音频处理电路的具体位置也可能不同。智能手机的音频处理电路主要包括音频信号处理电路、基带信号处理电路、音频功率放大器、耳机信号放大器、听筒、扬声器、麦克风及耳机接口等。其中，音频信号处理电路是整个音频处理电路的核心。音频处理电路主要由接收音频电路、送话电路、耳机通话电路等组成，包括模拟音频的模拟/数字(A/D)转换、数字/模拟(A/D)转换、数字语音信号处理及模拟音频放大电路等。FIG. 2 is a schematic structural diagram of an audio processing hardware system of a smart phone according to an embodiment of the present invention. The audio processing circuit is generally located in the main control circuit board. Due to the different designs of different mobile phones, the specific location of the audio processing circuit may also be different. The audio processing circuit of a smartphone mainly includes an audio signal processing circuit, a baseband signal processing circuit, an audio power amplifier, a headphone signal amplifier, an earpiece, a speaker, a microphone and a headphone interface. Among them, the audio signal processing circuit is the core of the entire audio processing circuit. The audio processing circuit is mainly composed of receiving audio circuit, sending circuit, earphone calling circuit, etc., including analog/digital (A/D) conversion of analog audio, digital/analog (A/D) conversion, digital voice signal processing and analog audio Amplifier circuit, etc.
在通话时，首先通话本地端麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经内部的多模转换器进行A/D转换，得到数字音频信号；其次把此数字音频信号送到基带处理器，进行语音编码、信道编码等处理；再次进行加密、交织等一系列处理；最后送到基带处理器中的数字窄带制调模块进行调制，产生发射基带信号送入射频电路调制成发射中频，发送给通话对方。During a call, firstly, the local microphone of the call converts the mechanical sound wave signal of the sound into an analog audio signal, which is amplified by the analog audio amplifier circuit, and then A/D converted by the internal multi-mode converter to obtain a digital audio signal; The digital audio signal is sent to the baseband processor for voice coding, channel coding and other processing; again, a series of processes such as encryption and interleaving are carried out; finally, it is sent to the digital narrowband modulation module in the baseband processor for modulation to generate a transmitting baseband signal and send it to the The radio frequency circuit is modulated to transmit intermediate frequency and sent to the other party of the call.
在录音时，与上述过程类似，首先由麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经过A/D转换后得到数字音频信号，按照预设的音频格式进行编码及存储。When recording, similar to the above process, the mechanical sound wave signal of the sound is first converted into an analog audio signal by the microphone, amplified by the analog audio amplifier circuit, and the digital audio signal is obtained after A/D conversion, which is performed according to the preset audio format. encoding and storage.
本发明实施例中麦克风采集的音频信号可以是上述的由机械声波信号转换而来的模拟音频信号，也可以是经过放大后的模拟音频信号，还可以是经过A/D转换后的数字音频信号等，本发明实施例不作限定。The audio signal collected by the microphone in the embodiment of the present invention may be the above-mentioned analog audio signal converted from the mechanical sound wave signal, or may be an amplified analog audio signal, or may be an A/D converted digital audio signal etc., which are not limited in the embodiments of the present invention.
如图3所示，本实施例提供的音频系统架构主要包括用户空间、内核空间和硬件系统。用户空间包括应用(Application)层、应用框架(Framework)层和硬件抽象层(HardwareAbstraction Layer，HAL)，内核空间包括驱动(Driver)层，。应用层是音频体系的最上层，可通过编写一个应用程序来执行对应的逻辑操作，例如检测触发录音事件的应用程序，预先设置标准音频条件，下发音频播放指令等。应用框架层包括音频控制接口和标准化插件模块负责提供音频播放形式控制接口，以及扬声器音量大小控制接口等。应用框架层提供了AudioTrack和AudioRecorder两个类，以及AudioManager、AudioService及AudioSystem类。在应用框架层和硬件抽象层之间还包括一个系统运行库(Libraries)层。我们知道，framework层的很多类，实际上只是应用程序使用Android库文件的“中介”而已。因为上层应用一般采用java语言编写，它们需要最直接的java接口的支持，这就是framework层存在的意义之一。而作为“中介”，它们并不会真正去实现具体的功能，或者只实现其中的一部分功能，而把主要重心放在库中来完成。比如上面的AudioTrack、AudioRecorder、MediaPlayer和MediaRecorder等等在库中都能找到相对应的类。这一部分代码集中放置在工程的frameworks/av/media/libmedia中，多数是C++语言编写的。音频方面的硬件抽象层主要分为两部分，即AudioFlinger和AudioPolicyService。实际上后者并不是一个真实的设备，只是采用虚拟设备的方式来让厂商可以方便地定制出自己的策略。根据产品的不同，音频设备存在很大差异，在Android的音频架构中，这些问题都是由HAL层的audio.primary等来解决的，而不需要大规模地修改上层实现。硬件抽象层是应用框架层到驱动层的过渡，以实现底层硬件的兼容。驱动层按照音频编解码器的特性对其进行控制，确保音频编解码器可以正常工作，将音频编解码器获取到的音频数据提供给系统层。本发明实施例中在进行音频信号采集时，主要涉及的类为上述的AudioRecorder类。As shown in FIG. 3 , the audio system architecture provided by this embodiment mainly includes a user space, a kernel space, and a hardware system. The user space includes an application (Application) layer, an application framework (Framework) layer and a hardware abstraction layer (HardwareAbstraction Layer, HAL), and the kernel space includes a driver (Driver) layer. The application layer is the top layer of the audio system. You can write an application program to perform corresponding logical operations, such as detecting the application program that triggers the recording event, pre-setting standard audio conditions, and issuing audio playback instructions. The application framework layer includes an audio control interface and a standardized plug-in module responsible for providing an audio playback form control interface, as well as a speaker volume control interface. The application framework layer provides AudioTrack and AudioRecorder classes, as well as AudioManager, AudioService and AudioSystem classes. A system runtime library (Libraries) layer is also included between the application framework layer and the hardware abstraction layer. We know that many classes in the framework layer are actually just "intermediaries" for applications to use Android library files. Because upper-layer applications are generally written in java language, they need the support of the most direct java interface, which is one of the meanings of the existence of the framework layer. As "intermediaries", they do not really implement specific functions, or only implement a part of them, and focus on the library to complete. For example, the above AudioTrack, AudioRecorder, MediaPlayer and MediaRecorder can find corresponding classes in the library. This part of the code is placed in the frameworks/av/media/libmedia of the project, and most of them are written in C++ language. The hardware abstraction layer in audio is mainly divided into two parts, AudioFlinger and AudioPolicyService. In fact, the latter is not a real device, but only uses a virtual device to allow manufacturers to easily customize their own policies. Depending on the product, there are great differences in audio devices. In the audio architecture of Android, these problems are solved by the audio.primary of the HAL layer, without the need to modify the upper layer implementation on a large scale. The hardware abstraction layer is the transition from the application framework layer to the driver layer to realize the compatibility of the underlying hardware. The driver layer controls the audio codec according to its characteristics, ensures that the audio codec can work normally, and provides the audio data obtained by the audio codec to the system layer. In the embodiment of the present invention, when the audio signal is collected, the mainly involved class is the above-mentioned AudioRecorder class.
步骤102、对所述音频信号对应的声音响度进行分析。Step 102: Analyze the sound loudness corresponding to the audio signal.
声音的三个主要属性为音量、音调和音色。其中，音量又称响度或音强，是指人耳对所听到的声音大小强弱的主观感受，其客观评价尺度是声音的振幅大小。振幅指物体震动过程中偏离原来位置的最大距离，人耳听到的声音的响度与音源的振幅相关，一般振幅越大响度越强。The three main properties of sound are volume, pitch, and timbre. Among them, volume, also known as loudness or sound intensity, refers to the human ear's subjective perception of the intensity of the sound heard, and its objective evaluation scale is the amplitude of the sound. Amplitude refers to the maximum distance that the object deviates from the original position during the vibration process. The loudness of the sound heard by the human ear is related to the amplitude of the sound source. Generally, the larger the amplitude, the stronger the loudness.
示例性的，以声源为用户嘴巴为例，用户在通话时虽然能够听到自己说话的声音大小，但是无法知道当前说话的音量对于通话对端的人来说声音是大还是小，若声音较小，对方可能听不清，若声音较大，可能让对方感到震耳；用户在录音时也能够听到自己说话的声音大小，但是无法知道终端记录的自己的声音的大小，若声音较小，播放录音时可能听不清，若声音较大，播放录音时可能让收听者感到不适。本发明实施例中，对音频信号对应的声音响度进行分析，以获知终端采集的音频信号对应的声音响度是否合适。Exemplarily, taking the sound source as the user's mouth as an example, although the user can hear the loudness of his own speaking during a call, he cannot know whether the current speaking volume is loud or small for the person on the other end of the call. If the sound is too small, the other party may not be able to hear clearly. If the sound is louder, the other party may feel deafening. The user can hear the volume of his own voice when recording, but he cannot know the volume of his own voice recorded by the terminal. , the recording may not be heard clearly, and if the sound is loud, the listener may feel uncomfortable when playing the recording. In the embodiment of the present invention, the sound loudness corresponding to the audio signal is analyzed to know whether the sound loudness corresponding to the audio signal collected by the terminal is appropriate.
示例性的，可以预设时段为分析单位，分析每个预设时段内的声音响度的大小，可将当前预设时段对应的声音响度记为当前声音响度。预设时段可以是以当前时刻为起点向前计时的预设时间长度。为了保证实时性，可以将预设时段对应的预设时间长度设置的短一些，例如是以当前时刻为起点向前计时的0.5秒内。Exemplarily, a preset time period may be used as an analysis unit, the size of the sound loudness in each preset time period may be analyzed, and the sound loudness corresponding to the current preset time period may be recorded as the current sound loudness. The preset time period may be a preset time length that is counted forward starting from the current moment. In order to ensure real-time performance, the preset time length corresponding to the preset time period may be set to be shorter, for example, within 0.5 seconds from the current moment as the starting point to count forward.
步骤103、根据分析结果提示用户对通话状态或录音状态进行调整。Step 103: Prompt the user to adjust the call state or the recording state according to the analysis result.
示例性的，影响终端麦克风采集的音频信号对应的声音响度的因素有很多，其中，与通话状态或录音状态相关的因素一般可以由用户来决定。例如，与通话状态或录音状态相关的因素可包括用户自身说话声音的大小或者用户希望记录的其他声源的发声强度的大小，还可包括声源(如用户嘴巴或其他声源)与麦克风的相对距离，还可包括麦克风的朝向等等。Exemplarily, there are many factors that affect the sound loudness corresponding to the audio signal collected by the microphone of the terminal, wherein the factors related to the call state or the recording state can generally be determined by the user. For example, the factors related to the call state or the recording state may include the loudness of the user's own voice or the sound intensity of other sound sources that the user wishes to record, and may also include the difference between the sound source (such as the user's mouth or other sound sources) and the microphone. The relative distance may also include the orientation of the microphone and so on.
示例性的，可由系统默认确定或根据实际情况确定满足要求的音频信号的目标声音响度信息，也可由用户提前根据需求确定满足要求的音频信号的目标声音响度。在对当前采集的音频信号进行声音响度的分析后，将当前声音响度与目标声音响度进行比对，然后提示用户进行相应的调整。例如，在录音过程中，判断出当前声音响度比目标声音响度小，则可提示用户提高说话声音的强度，或者将麦克风靠近嘴边等等。Exemplarily, the target sound loudness information of the audio signal satisfying the requirement can be determined by default by the system or determined according to the actual situation, or the target sound loudness information of the audio signal satisfying the requirement can be determined by the user in advance according to the requirement. After analyzing the sound loudness of the currently collected audio signal, the current sound loudness is compared with the target sound loudness, and then the user is prompted to make corresponding adjustments. For example, during the recording process, if it is determined that the loudness of the current sound is lower than the loudness of the target sound, the user may be prompted to increase the intensity of the speaking sound, or bring the microphone close to the mouth, and so on.
可选的，可以文字形式、语音形式或指示灯形式对用户进行提醒。例如，可以在显示屏上显示调整方式的描述文字；可以播放调整方式的提示语音，并可在麦克风采集的音频信号中滤除该提示语音；可以以指示灯的不同颜色代表不同的调整方式，或以指示灯不同的闪烁频率代表不同的调整方式等等。Optionally, the user can be reminded in the form of text, voice or indicator light. For example, the description text of the adjustment method can be displayed on the display screen; the prompt voice of the adjustment method can be played, and the prompt voice can be filtered out from the audio signal collected by the microphone; the different colors of the indicator light can represent different adjustment methods, Or use the different flashing frequencies of the indicator lights to represent different adjustment methods and so on.
本发明实施例提供的提示方法，在通话或录音过程中，根据对麦克风采集的音频信号对应的声音响度进行分析，并根据分析结果提示用户对通话状态或录音状态进行调整。通过采用上述技术方案，在通话或录音过程中，能够及时准确地提示用户调整通话状态或录音状态，可以保持良好的通话效果或录音效果。In the prompting method provided by the embodiment of the present invention, during the call or recording process, the sound loudness corresponding to the audio signal collected by the microphone is analyzed, and the user is prompted to adjust the call state or the recording state according to the analysis result. By adopting the above technical solution, during the call or recording process, the user can be promptly and accurately prompted to adjust the call state or the recording state, and a good call effect or recording effect can be maintained.
在一些实施例中，所述根据分析结果提示用户对通话状态或录音状态进行调整，包括：根据分析结果提示用户对所述麦克风和声源的相对距离和/或声源的发声情况进行调整。这样设置的好处在于，调整方式简单快捷，用户能够根据提示快速做出反应，从而能够在需要调整时快速调整至所需状态，满足通话及录音对实时性的较高要求。In some embodiments, the prompting the user to adjust the call state or the recording state according to the analysis result includes: prompting the user to adjust the relative distance between the microphone and the sound source and/or the sounding condition of the sound source according to the analysis result. The advantage of this setting is that the adjustment method is simple and quick, and the user can quickly respond according to the prompt, so that the user can quickly adjust to the desired state when adjustment is required, and meet the high real-time requirements of calls and recordings.
在一些实施例中，所述对所述音频信号对应的声音响度进行分析，可包括：对所述音频信号的振幅信息进行分析，以得到声音响度分析结果。如前所述，声音响度的客观评价尺度是声音的振幅大小，而音频信号由声音的机械声波信号转换而来，因此可采用振幅信息对音频信号的声音响度进行分析。振幅越大，声音响度越大，也即声音能量值越高。示例性的，可以预设时段为分析单位，在预设时段内以预设采样频率对音频信号的振幅进行采集，获取多个振幅值，将预设时段内的振幅平均值作为当前声音响度。此处优化将对声音响度的分析转化为对振幅信息的分析，可简化分析过程，提高分析速度。In some embodiments, the analyzing the sound loudness corresponding to the audio signal may include: analyzing amplitude information of the audio signal to obtain a sound loudness analysis result. As mentioned above, the objective evaluation scale of sound loudness is the amplitude of the sound, and the audio signal is converted from the mechanical sound wave signal of the sound, so the amplitude information can be used to analyze the sound loudness of the audio signal. The larger the amplitude, the louder the sound, that is, the higher the sound energy value. Exemplarily, a preset period may be used as an analysis unit, the amplitude of the audio signal is collected at a preset sampling frequency within the preset period, a plurality of amplitude values are obtained, and the average value of the amplitude within the preset period is used as the current sound loudness. The optimization here converts the analysis of the loudness of the sound into the analysis of the amplitude information, which can simplify the analysis process and improve the analysis speed.
在一些实施例中，对所述音频信号的振幅信息进行分析，以得到声音响度分析结果，可进一步包括：提取所述音频信号中对应人声的振幅信息；对所述对应人声的振幅信息进行分析，以得到声音响度分析结果。示例性的，在通话过程中，人声是音频信号中的主体，其他环境声音可视为是干扰声音；此外，在录音时，用户可以选择人声录音模式，这时，人声也是音频信号中的主体，其他环境声音可视为是干扰声音。在这些情况下，声源即用户的嘴巴，在提取音频信号中对应人声的振幅信息后，可大幅减少需要分析的数据，进而提高分析速度，也能够更及时地对用户进行提示，有助于进一步提高针对通话状态或录音状态的调整时效性。In some embodiments, analyzing the amplitude information of the audio signal to obtain a sound loudness analysis result may further include: extracting the amplitude information corresponding to the human voice in the audio signal; Analysis is performed to obtain sound loudness analysis results. Exemplarily, during a call, the human voice is the main body in the audio signal, and other ambient sounds can be regarded as interfering sounds; in addition, during recording, the user can select a voice recording mode, and at this time, the human voice is also an audio signal. The main subject in the , other ambient sounds can be considered as distracting sounds. In these cases, the sound source is the user's mouth. After extracting the amplitude information corresponding to the human voice in the audio signal, the data to be analyzed can be greatly reduced, thereby improving the analysis speed and prompting the user in a more timely manner, which is helpful for In order to further improve the timeliness of adjustment of the call status or recording status.
在一些实施例中，根据分析结果提示用户对所述麦克风和声源的相对距离进行调整，可包括：当所述声音响度分析结果中包括当前声音响度小于第一预设响度阈值时，提示用户将所述麦克风和声源的相对距离调小；也可包括：当所述声音响度分析结果中包括当前声音响度大于第二预设响度阈值时，提示用户将所述麦克风和声源的相对距离调大。当然，也可同时包括上述两种方式。其中，第一预设响度阈值和第二预设响度阈值可以相同，也可以不同，具体数值可以是预先设置的固定值，也可以是根据实际情况进行动态调整的变化值。In some embodiments, prompting the user to adjust the relative distance between the microphone and the sound source according to the analysis result may include: when the sound loudness analysis result includes that the current sound loudness is less than a first preset loudness threshold, prompting the user Adjusting the relative distance between the microphone and the sound source; it may also include: when the sound loudness analysis result includes that the current sound loudness is greater than a second preset loudness threshold, prompting the user to set the relative distance between the microphone and the sound source turn up. Of course, the above two methods can also be included at the same time. Wherein, the first preset loudness threshold and the second preset loudness threshold may be the same or different, and the specific value may be a preset fixed value, or may be a variable value dynamically adjusted according to the actual situation.
示例性的，在当前声音响度小于第一预设响度阈值时，可说明音频信号中当前声音响度较小，通话对端可能无法听清本端用户说的话，或者录音文件在后续播放时可能导致他人听不清此时录取的声音，因此，可提示用户将麦克风和声源的相对距离调小，以使接下来采集的音频信号中的声音响度有所提高。示例性的，在当前声音响度大于或等于第一预设响度阈值时，可不进行提示。这样设置的好处在于，可适用于对声音响度上限没有要求的应用场景，保证提示效率。Exemplarily, when the current sound loudness is less than the first preset loudness threshold, it can indicate that the current sound loudness in the audio signal is relatively small, and the other end of the call may not be able to hear what the local user says clearly, or the recording file may cause a The sound recorded at this time cannot be heard clearly by others. Therefore, the user may be prompted to reduce the relative distance between the microphone and the sound source, so as to increase the loudness of the sound in the audio signal collected next. Exemplarily, when the current sound loudness is greater than or equal to the first preset loudness threshold, prompting may not be performed. The advantage of this setting is that it can be applied to application scenarios that do not require the upper limit of sound loudness to ensure prompt efficiency.
示例性的，在当前声音响度大于第二预设响度阈值时，可说明音频信号中当前声音响度较大，传到通话对端可能会使对方感到震耳，或者录音文件在后续播放时可能导致声音过大影响收听，因此，可提示用户将麦克风和声源的相对距离调大，以使接下来采集的音频信号中的声音响度有所降低。示例性的，在当前声音响度小于或等于第二预设响度阈值时，可不进行提示。这样设置的好处在于，可适用于对声音响度下限没有要求的应用场景，保证提示效率。Exemplarily, when the loudness of the current sound is greater than the second preset loudness threshold, it can indicate that the loudness of the current sound in the audio signal is relatively large, and the transmission to the opposite end of the call may make the other party feel deafening, or the recording file may cause noise during subsequent playback. Too loud sound affects listening. Therefore, the user may be prompted to increase the relative distance between the microphone and the sound source, so that the loudness of the sound in the audio signal collected next is reduced. Exemplarily, when the current sound loudness is less than or equal to the second preset loudness threshold, the prompt may not be performed. The advantage of this setting is that it can be applied to application scenarios where there is no requirement for the lower limit of sound loudness to ensure prompt efficiency.
示例性的，可将上述两种提示方式进行结合，即当前声音响度较小时和较大时均会进行提醒，而当前声音响度大于或等于第一预设响度阈值且小于或等于第二预设响度阈值时，说明此时音频信号中的声音响度比较合适，可不进行提示。这样设置的好处在于，可适用于对声音响度上限和下限均有要求的应用场景，保证提示的准确度。Exemplarily, the above two prompting methods can be combined, that is, a prompt will be given when the current sound loudness is small and large, and the current sound loudness is greater than or equal to the first preset loudness threshold and less than or equal to the second preset loudness threshold. When the loudness threshold is set, it indicates that the sound loudness in the audio signal is appropriate at this time, and no prompt is required. The advantage of this setting is that it can be applied to application scenarios that require both the upper and lower limits of sound loudness to ensure the accuracy of prompts.
在一些实施例中，根据分析结果提示用户对声源的发声情况进行调整，可包括：当所述声音响度分析结果中包括当前声音响度小于第三预设响度阈值时，提示用户将声源的发声强度调大；还可包括：当所述声音响度分析结果中包括当前声音响度大于第四预设响度阈值时，提示用户将声源的发声强度调小。其中，第三预设响度阈值和第四预设响度阈值可以相同，也可以不同；第三预设响度阈值和上述第一预设响度阈值可以相同，也可以不同；第四预设响度阈值和上述第二预设响度阈值可以相同，也可以不同。具体数值可以是预先设置的固定值，也可以是根据实际情况进行动态调整的变化值。In some embodiments, prompting the user to adjust the sounding condition of the sound source according to the analysis result may include: when the sound loudness analysis result includes that the current sound loudness is less than a third preset loudness threshold, prompting the user to adjust the sound source The sound intensity is increased; it may further include: when the sound loudness analysis result includes that the current sound loudness is greater than the fourth preset loudness threshold, prompting the user to reduce the sound intensity of the sound source. Wherein, the third preset loudness threshold and the fourth preset loudness threshold may be the same or different; the third preset loudness threshold and the first preset loudness threshold may be the same or different; the fourth preset loudness threshold and The above-mentioned second preset loudness threshold may be the same or different. The specific value may be a preset fixed value, or a change value that is dynamically adjusted according to the actual situation.
示例性的，在当前声音响度小于第三预设响度阈值时，可说明音频信号中当前声音响度较小，通话对端可能无法听清本端用户说的话，或者录音文件在后续播放时可能导致他人听不清此时录取的声音，因此，可提示用户将麦克风和声源的相对距离调小，以使接下来采集的音频信号中的声音响度有所提高。示例性的，在当前声音响度大于或等于第三预设响度阈值时，可不进行提示。这样设置的好处在于，可适用于对声音响度上限没有要求的应用场景，保证提示效率。Exemplarily, when the current sound loudness is less than the third preset loudness threshold, it can indicate that the current sound loudness in the audio signal is relatively small, and the opposite end of the call may not be able to hear what the user on the local end said, or the recording file may cause The sound recorded at this time cannot be heard clearly by others. Therefore, the user may be prompted to reduce the relative distance between the microphone and the sound source, so as to increase the loudness of the sound in the audio signal collected next. Exemplarily, when the current sound loudness is greater than or equal to the third preset loudness threshold, prompting may not be performed. The advantage of this setting is that it can be applied to application scenarios that do not require the upper limit of sound loudness to ensure prompt efficiency.
示例性的，在当前声音响度大于第四预设响度阈值时，可说明音频信号中当前声音响度较大，传到通话对端可能会使对方感到震耳，或者录音文件在后续播放时可能导致声音过大影响收听，因此，可提示用户将麦克风和声源的相对距离调大，以使接下来采集的音频信号中的声音响度有所降低。示例性的，在当前声音响度小于或等于第四预设响度阈值时，可不进行提示。这样设置的好处在于，可适用于对声音响度下限没有要求的应用场景，保证提示效率。Exemplarily, when the loudness of the current sound is greater than the fourth preset loudness threshold, it can indicate that the loudness of the current sound in the audio signal is relatively large, and the transmission to the opposite end of the call may cause the other party to feel deafening, or the recording file may cause noise during subsequent playback. Too loud sound affects listening. Therefore, the user may be prompted to increase the relative distance between the microphone and the sound source, so that the loudness of the sound in the audio signal collected next is reduced. Exemplarily, when the current sound loudness is less than or equal to the fourth preset loudness threshold, no prompting may be performed. The advantage of this setting is that it can be applied to application scenarios where there is no requirement for the lower limit of sound loudness to ensure prompt efficiency.
示例性的，可将上述两种调整方式进行结合，即当前声音响度较小时和较大时均会进行提醒，而当前声音响度大于或等于第三预设响度阈值且小于或等于第四预设响度阈值时，说明此时音频信号中的声音响度比较合适，可不进行提示。这样设置的好处在于，可适用于对声音响度上限和下限均有要求的应用场景，保证提示的准确度。Exemplarily, the above two adjustment methods can be combined, that is, a reminder will be given when the current sound loudness is small and large, and the current sound loudness is greater than or equal to the third preset loudness threshold and less than or equal to the fourth preset loudness threshold. When the loudness threshold is set, it indicates that the sound loudness in the audio signal is appropriate at this time, and no prompt is required. The advantage of this setting is that it can be applied to application scenarios that require both the upper and lower limits of sound loudness to ensure the accuracy of prompts.
可选的，还可提示用户同时对麦克风和声源的相对距离和声源的发声情况进行调整。示例性的，当所述声音响度分析结果中包括当前声音响度小于第五预设响度阈值时，提示用户将麦克风和声源的相对距离调小并将声源的发声强度调大；和/或，当所述声音响度分析结果中包括当前声音响度大于第六预设响度阈值时，提示用户将所述麦克风和声源的相对距离调大并将声源的发声强度调小。这样设置的好处在于，能够快速将通话状态或录音状态调整到理想状态。Optionally, the user may also be prompted to adjust the relative distance between the microphone and the sound source and the sounding condition of the sound source at the same time. Exemplarily, when the sound loudness analysis result includes that the current sound loudness is less than the fifth preset loudness threshold, prompt the user to reduce the relative distance between the microphone and the sound source and increase the sound intensity of the sound source; and/or , when the sound loudness analysis result includes that the current sound loudness is greater than the sixth preset loudness threshold, prompt the user to increase the relative distance between the microphone and the sound source and decrease the sound intensity of the sound source. The advantage of this setting is that you can quickly adjust the call state or recording state to the ideal state.
在一些实施例中，还可根据当前声音响度与对应的预设响度阈值之间的差距(如差值)来对用户进行更具体的提示。示例性的，不同的差值对应不同的调整值，对应关系可预先根据仿真等方式确定。例如，当前声音响度与第一预设响度阈值之间的差值为a，对应的相对距离调整值为5厘米，则提示用户将所述麦克风和声源的相对距离调小5厘米。这样设置的好处在于，对用户的提示更加明确，方便用户快速将通话状态或录音状态调整到理想状态。In some embodiments, a more specific prompt may also be given to the user according to the difference (eg, the difference) between the current sound loudness and the corresponding preset loudness threshold. Exemplarily, different difference values correspond to different adjustment values, and the corresponding relationship may be determined in advance according to simulation or the like. For example, if the difference between the current sound loudness and the first preset loudness threshold is a, and the corresponding relative distance adjustment value is 5 cm, the user is prompted to reduce the relative distance between the microphone and the sound source by 5 cm. The advantage of this setting is that the prompt to the user is more clear, and it is convenient for the user to quickly adjust the call state or recording state to an ideal state.
在一些实施例中，当被触发的事件为预设通话事件时，所述根据分析结果提示用户对所述麦克风和声源的相对距离进行调整，还可包括：获取通话对端联系人的属性信息和/或通话对端的情景模式信息；根据所述属性信息和/或所述情景模式信息确定相应的第一预设响度阈值和/或第二预设响度阈值。这样设置的好处在于，能够根据实际情况更加准确地确定第一预设响度阈值和/或第二预设响度阈值，进一步提升通话效果。In some embodiments, when the triggered event is a preset call event, the prompting the user to adjust the relative distance between the microphone and the sound source according to the analysis result may further include: acquiring attributes of the contact at the opposite end of the call information and/or context mode information of the call peer; determine the corresponding first preset loudness threshold and/or second preset loudness threshold according to the attribute information and/or the context mode information. The advantage of this setting is that the first preset loudness threshold and/or the second preset loudness threshold can be more accurately determined according to the actual situation, so as to further improve the call effect.
示例性的，属性信息可以包括年龄(或年龄段)，或者包括是否为老人或是否为孩子等。可选的，获取通话对端联系人的属性信息可包括：获取通话对端联系人在通讯录中的备注信息，从所述备注信息中提取属性信息；也可包括对通话对端联系人的声音进行语音识别，根据识别结果确定相应的属性信息。当对方为老人时，可能听力较差，所需的声音响度应大一些，因此可将第一预设响度阈值和/或第二预设响度阈值设置得高一些。Exemplarily, the attribute information may include age (or age group), or whether it is an elderly person or a child, and so on. Optionally, acquiring the attribute information of the contact at the opposite end of the call may include: obtaining the remark information of the contact at the opposite end of the call in the address book, and extracting the attribute information from the remark information; it may also include information on the contact at the opposite end of the call. Voice recognition is performed on the sound, and corresponding attribute information is determined according to the recognition result. When the other party is an elderly person, the hearing may be poor, and the required sound loudness should be higher. Therefore, the first preset loudness threshold and/or the second preset loudness threshold may be set higher.
示例性的，通话对端的情景模式信息可包括静音模式、会议模式、正常模式和户外模式等等模式信息。用户通常会根据自己所处环境设置对应的情景模式，例如在上课或者开会等相对比较安静的环境中，可能会选择静音模式或会议模式，在外面比较吵的环境中可能会选择户外模式，在这些环境中接听电话时，可能对声音响度有不同的需求。例如，会议模式时，由于环境比较安静，声音响度不必很大即可听清对方声音；而户外模式时，由于环境比较吵闹，需要比较大的声音响度才能听清对方声音。基于以上原因，可预先设定好不同的情景模式与第一预设响度阈值和/或第二预设响度阈值的对应关系，在实际的通话过程中，能够根据获取到的情景模式信息来确定相应的第一预设响度阈值和/或第二预设响度阈值。可选的，获取通话对端的情景模式信息具体可包括：向通话对端发送情景模式信息获取请求，接收通话对端根据所述情景模式信息获取请求反馈的情景模式信息。Exemplarily, the profile mode information of the call peer may include mode information such as silent mode, conference mode, normal mode, and outdoor mode. Users usually set the corresponding scene mode according to their environment. For example, in a relatively quiet environment such as a class or a meeting, they may choose the silent mode or the conference mode. In a noisy environment outside, they may choose the outdoor mode. Answering a phone call in these environments may have different needs for sound loudness. For example, in the conference mode, because the environment is relatively quiet, the loudness of the voice does not need to be very loud to hear the voice of the other party; while in the outdoor mode, because the environment is noisy, the loudness of the voice needs to be louder to hear the voice of the other party. Based on the above reasons, the corresponding relationship between different scene modes and the first preset loudness threshold and/or the second preset loudness threshold can be preset. In the actual call process, it can be determined according to the obtained scene mode information. The corresponding first preset loudness threshold and/or second preset loudness threshold. Optionally, acquiring the context mode information of the call peer end may specifically include: sending a context mode information acquisition request to the call peer end, and receiving the context mode information fed back by the call peer end according to the context mode information acquisition request.
在一些实施例中，当被触发的事件为预设通话事件时，所述根据分析结果提示用户对所述麦克风和声源的相对距离进行调整，还包括：获取通话对端联系人的属性信息和/或通话对端的情景模式信息；根据所述属性信息和/或所述情景模式信息确定相应的第三预设响度阈值和/或第四预设响度阈值。具体的实现细节可参见上文中对根据所述属性信息和/或所述情景模式信息确定相应的第一预设响度阈值和/或第二预设响度阈值进行说明的相关内容。这样设置的好处在于，能够根据实际情况更加准确地确定第三预设响度阈值和/或第四预设响度阈值，进一步提升通话效果。In some embodiments, when the triggered event is a preset call event, the prompting the user to adjust the relative distance between the microphone and the sound source according to the analysis result further includes: acquiring attribute information of the contact at the opposite end of the call and/or the context mode information of the call peer; determine the corresponding third preset loudness threshold and/or the fourth preset loudness threshold according to the attribute information and/or the context mode information. For specific implementation details, please refer to the above related content for the description of the determination of the corresponding first preset loudness threshold and/or the second preset loudness threshold according to the attribute information and/or the scene mode information. The advantage of this setting is that the third preset loudness threshold and/or the fourth preset loudness threshold can be more accurately determined according to the actual situation, so as to further improve the call effect.
