步骤201，从目标客户端获取第一用户心音音频。Step 201: Acquire the audio of the first user's heart sound from the target client.
在本实施例中，用于推送信息的方法的执行主体(例如图1所示的服务器)可以通过有线连接方式或者无线连接方式从目标客户端获取第一用户心音音频。其中，上述目标客户端可以是与上述执行主体通信连接的客户端。上述第一用户心音音频可以是某人由心肌收缩、心脏瓣膜关闭和血液撞击心室壁、大动脉壁等引起的振动所产生的声音的音频。In this embodiment, the execution body of the method for pushing information (for example, the server shown in FIG. 1 ) may acquire the audio of the first user's heart sound from the target client through a wired connection or a wireless connection. Wherein, the above-mentioned target client may be a client that is communicatively connected to the above-mentioned execution body. The above-mentioned first user heart sound audio may be the audio of someone's sound produced by vibrations caused by contraction of the heart muscle, closure of heart valves, and blood hitting the walls of the ventricle, the aorta, and the like.
可选的，上述第一用户心音音频可以由听诊器获取，由换能器等仪器记录。该听诊器可以与该换能器通信连接，该换能器可以与上述目标客户端通信连接。上述第一用户心音音频也可以由安装在目标客户端上的心音音频采集装置获取。Optionally, the above-mentioned audio of the first user's heart sound may be acquired by a stethoscope and recorded by an instrument such as a transducer. The stethoscope can be communicatively connected to the transducer, and the transducer can be communicatively connected to the aforementioned target client. The above-mentioned first user's heart sound audio may also be acquired by a heart sound audio collection device installed on the target client.
在本实施例的一些可选的实现方式中，从目标客户端获取第一用户心音音频，包括：从目标客户端获取听诊器采集到的第一用户心音音频。其中，上述听诊器可以与上述目标客户端通信连接。通过上述目标客户端，用户可以将自己的心音音频发送至上述执行主体。In some optional implementation manners of this embodiment, acquiring the audio of the first user's heart sound from the target client includes: acquiring the audio of the first user's heart sound collected by a stethoscope from the target client. Wherein, the above-mentioned stethoscope may be connected in communication with the above-mentioned target client. Through the above-mentioned target client, the user can send his own heart sound audio to the above-mentioned executive body.
步骤202，提取第一用户心音音频的音频特征。
在本实施例中，上述执行主体可以提取步骤201所获取到的第一用户心音音频的音频特征。其中，上述音频特征可以是任一个或多个音频的特征。例如，上述音频特征可以包括但不限于以下至少一项：频率、波长、过零率、音质、音色、共振峰、短时能量、短时平均幅度差、短时功率谱密度等等。In this embodiment, the above-mentioned execution body may extract the audio features of the first user's heart sound audio obtained in
应该理解，针对不同的音频特征，上述执行主体可以采用不同的音频特征提取方式。在这里，以音频特征为功率谱密度为例，上述执行主体可以基于周期图法或平均周期图法提取第一用户心音音频的功率谱密度。It should be understood that, for different audio features, the above-mentioned executive body may adopt different audio feature extraction methods. Here, taking the audio feature as the power spectral density as an example, the above-mentioned executing subject may extract the power spectral density of the audio of the first user's heart sound based on the periodogram method or the average periodogram method.
步骤203，基于音频特征，在预先确定的音乐集合中确定与第一用户心音音频相匹配的音乐。
在本实施例中，上述执行主体可以基于步骤202得到的音频特征，在预先确定的音乐集合中确定与第一用户心音音频相匹配的音乐。其中，上述预先确定的音乐集合可以是技术人员或者管理人员预先确定的音乐的集合。例如，上述预先确定的音乐集合可以是某一个或者某几个歌手演唱的音乐的集合；也可以是属于某一个或多个风格(例如欧美、轻音乐、伤感、励志、怀旧、治愈)的音乐的集合。作为示例，上述音乐集合可以是音乐数据库，也可以是存储于存储设备中的音乐的集合。In this embodiment, the above-mentioned execution body may determine music that matches the audio of the first user's heart sound in a predetermined music set based on the audio feature obtained in
作为示例，上述相匹配的音乐可以如下确定：As an example, the above matching music can be determined as follows:
首先，上述执行主体可以确定出上述音乐集合中的音乐的音频特征的特征曲线。其中，上述特征曲线可以是技术人员预先确定的用于表征某一音频特征的特征值与另一音频特征的特征值(也可以是其他属性值，例如时间)之间的关系的曲线。示例性的，上述特征曲线可以是用于表征频率的值与过零率的值之间的关系的曲线。First, the above-mentioned executive body may determine the characteristic curve of the audio characteristics of the music in the above-mentioned music collection. The above characteristic curve may be a curve pre-determined by a technician to characterize the relationship between a characteristic value of a certain audio feature and a characteristic value of another audio characteristic (it may also be other attribute values, such as time). Exemplarily, the above-mentioned characteristic curve may be a curve used to characterize the relationship between the value of the frequency and the value of the zero-crossing rate.
然后，上述执行主体可以将第一用户心音音频的音频特征的特征曲线与上述音乐集合中的音乐的音频特征的特征曲线进行一一比对，以确定出与第一用户心音音频的音频特征的特征曲线相似度最大的音乐集合中的音乐的音频特征的特征曲线，以及将该相似度最大的音乐集合中的音乐的音频特征的特征曲线对应的音乐确定为相匹配的音乐。Then, the above-mentioned executive body may compare the characteristic curve of the audio characteristic of the first user's heart sound audio with the characteristic curve of the audio characteristic of the music in the above-mentioned music collection, so as to determine the characteristic curve of the audio characteristic of the first user's heart sound audio. The characteristic curve of the audio characteristic of the music in the music set with the greatest similarity of the characteristic curve, and the music corresponding to the characteristic curve of the audio characteristic of the music in the music set with the greatest similarity is determined as the matched music.
步骤204，确定与相匹配的音乐的音频特征相匹配的第二用户心音音频。Step 204: Determine the second user's heart sound audio that matches the audio feature of the matched music.
在本实施例中，上述执行主体还可以确定与步骤203确定出的音乐的音频特征相匹配的第二用户心音音频。其中，第二用户心音音频可以是某人由心肌收缩、心脏瓣膜关闭和血液撞击心室壁、大动脉壁等引起的振动所产生的声音的音频。In this embodiment, the above-mentioned execution body may also determine the second user's heart sound audio that matches the audio feature of the music determined in
可以理解，第二用户心音音频与第一用户心音音频仅用作区分不同的用户心音音频，此处并不构成对用户心音音频的特殊限定。其中，第二用户心音音频与第一用户心音音频可以是不同的用户的心音音频。It can be understood that the second user's heart sound audio and the first user's heart sound audio are only used to distinguish different user's heart sound audio, and this does not constitute a special limitation on the user's heart sound audio. The heart sound audio of the second user and the heart sound audio of the first user may be the heart sound audio of different users.
作为示例，上述第二用户心音音频可以如下确定：As an example, the above-mentioned second user heart sound audio may be determined as follows:
首先，上述执行主体可以确定出某个用户集合(例如使用某应用的用户的集合或者所获取到各个的用户心音音频对应的各个用户的集合)中的每个用户的用户心音音频First, the above-mentioned executive body can determine the user heart sound audio of each user in a certain set of users (for example, a set of users who use a certain application or a set of each user corresponding to each acquired user heart sound audio).
然后，上述执行主体可以将上述相匹配的音乐的音频特征与每个用户的用户心音音频进行一一比对，以确定出与上述相匹配的音乐的音频特征的特征曲线相似度最大的用户的用户心音音频，以及将该相似度最大的用户的用户心音音频确定为第二用户心音音频。Then, the above-mentioned executive body can compare the audio features of the above-mentioned matched music with the user's heart sound audio of each user one-to-one, so as to determine the user whose characteristic curve similarity with the above-mentioned matched music audio characteristics is the greatest. The user heart sound audio, and the user heart sound audio of the user with the greatest similarity is determined as the second user heart sound audio.
可选的，上述第二用户心音音频也可以如下确定：Optionally, the second user's heart sound audio may also be determined as follows:
首先，上述执行主体可以获取预先确定的用户心音音频集合中的用户心音音频的音频特征集合。First, the above-mentioned executive body may acquire the audio feature set of the user's heart sound audio in the predetermined user's heart sound audio set.
然后，上述执行主体可以在所获取的音频特征集合中，确定与相匹配的音乐的音频特征相匹配的音频特征。Then, the above-mentioned executive body may determine an audio feature that matches the audio feature of the matched music in the acquired audio feature set.
最后，上述执行主体可以将相匹配的音频特征对应的用户心音音频，确定为与第二用户心音音频。Finally, the above executive body may determine the user's heart sound audio corresponding to the matched audio feature as the second user's heart sound audio.
在这里，上述相匹配的音频特征可以是与所提取的相匹配的音乐的音频特征具有相同(也可以是相差在一定范围内)的特征值的音频特征。Here, the above-mentioned matched audio features may be audio features having the same (or different within a certain range) feature value as the extracted audio features of the matched music.
步骤205，向目标客户端推送第二用户心音音频对应的用户的用户信息。Step 205: Push the user information of the user corresponding to the second user's heart sound audio to the target client.
