Fig. 1 is a schematic flow chart of a music recommendation method based on an intelligent terminal according to a preferred embodiment of the present invention. In this embodiment, the music recommendation method specifically includes the following steps:
s100: establishing an environmental sound database containing standard environmental sound information corresponding to various scenes on the intelligent terminal
The method includes the steps that environment sounds are collected to identify the current environment scene of a user so as to recommend proper music to the user, firstly, an environment sound database needs to be established, the database needs to contain environment sounds of various scenes, if the environment sounds are on a subway, standard environment sounds formed by subway sounds are contained, and if the environment sounds are KTV, standard environment sounds formed by KTV sound sounds are contained. The environment sound database can be established in various ways, and standard sounds with various scene characteristics, such as booming sound of a subway train and loud noise of KTV, can be directly downloaded from a network or introduced from other equipment, or can be acquired by acquiring sounds in a scene for many times and then learning through a sample. The standard environmental sound may be a unique characteristic sound of a scene, such as a booming sound of a subway in a subway environment, or may be a sound including a noise, such as a standard environmental sound including a human voice and a booming sound of a subway in a subway environment, where the standard environmental sound may be obtained by obtaining a common sound of a plurality of subway sounds. The specific method for using the standard environmental sound depends on the method for comparing the current environmental sound information with the standard environmental sound information.
S200: establishing a music recommendation list library at the intelligent terminal, wherein the music list library comprises music recommendation list composition formed by music associated with any scene in the plurality of scenes
The environment sound is collected to identify the current environment scene of the user so as to recommend proper music to the user, and besides an environment sound database needs to be established, a music recommendation list library also needs to be established. The music recommendation list library should include a plurality of scenes and a music recommendation list formed by music associated with any of the plurality of scenes. Particularly, three scenes of a subway, a house and a KTV are taken as examples, the music suitable for the three scenes is not very same, the subway is suitable for relatively noisy music due to large noise, the family is generally quite quiet and suitable for rest, so that the subway is suitable for quiet light music, and the KTV is generally mainly used for requesting songs and singing songs, so that the KTV is suitable for recommending popular song requesting songs, such as most dazzling folk winds, apples and the like. Therefore, the music recommendation list library should include three scenes, namely subway, home and KTV, each scene corresponds to one music recommendation list one by one, and when the system identifies that the current environment is in the subway or a certain scene, the music recommendation list library recommends the associated music list according to the music recommendation list library. The music recommendation list can be preset by a system, can be set by a user, is not fixed, and can be adjusted according to music selection of the user in the current scene and the like.
S300: acquiring current environment sound information of environment where intelligent terminal is located
After the environment sound database and the music recommendation list library are established, sound information of the current environment where the intelligent terminal is located needs to be collected, and current environment sound information is formed. Since various information, especially noise, generally exists in different scenes, various sound information also exists in the current environmental sound information. For example, when a subway starts, the sound collected on the subway not only includes the booming sound of the subway, but also includes a large amount of human voice, and when the sound information of the current environment is collected, the noise does not need to be removed, and the real and complete current environment sound is extracted. The method for collecting the current environmental sound is generally achieved by collecting sound wave signals through sound collection equipment or a sound collection system in the intelligent terminal.
S400: comparing the current environmental sound information with the standard environmental sound information, and pushing a music list associated with a scene corresponding to the standard environmental sound information in the music recommendation list library when the current environmental sound information is matched with the standard environmental sound information
After current environment sound information is acquired through sound acquisition equipment in the intelligent terminal, in order to identify the current environment, the current environment sound information needs to be compared with standard environment sound information, and when the current environment sound information is matched with the standard environment sound information, a music list associated with a scene corresponding to the standard environment sound information in the music recommendation list library is pushed to a user. Here, instead of playing music directly to the user, a list of music suitable for the current environment is pushed to the user, and the user selects whether to listen to the music or which music to listen to the music. The method for comparing the current environmental sound information with the standard environmental sound information can be through integral comparison, because the integral environmental sound under different environments is very different, such as subway, KTV, home, supermarket, and the integral is very different, therefore, the current environmental sound information can be separated into a plurality of groups of different sounds through integral comparison method, or through characteristic comparison, taking the environmental sound in subway as an example, it can be divided into booming sound and human voice when subway starts, at this time, the sound information in the environmental sound database should also be separated, the booming sound of subway is extracted as the standard environmental sound information of subway, when the comparison result after comparing the current environmental sound information with the standard environmental sound information of subway is that the current environmental sound information includes the standard environmental sound information of subway, the current environmental sound information should be considered to be matched with the standard environmental sound information, and at the moment, a music list associated with the subway scene corresponding to the standard environmental sound information is pushed according to the music recommendation list library, and music suitable for listening in the subway is pushed.
After the configuration is adopted, the current environment scene of the user can be identified by collecting the environment sound, and the music list suitable for the current environment is pushed for the user by combining the recommended music list intelligence under different scenes, so that the user experience is improved.
Referring to fig. 2, in a preferred embodiment, the step of establishing an ambient sound database containing standard ambient sound information corresponding to a plurality of scenes in the intelligent terminal specifically includes:
s101: collecting environmental sound information corresponding to multiple scenes
The method for extracting the standard environmental sound information by collecting the environmental sound information and learning through samples can be used for establishing the environmental sound database containing the standard environmental sound information corresponding to various scenes. Therefore, enough environmental sound information needs to be collected firstly, and in order to ensure the accuracy of the standard environmental sound information extraction result, the environmental sound needs to be collected for multiple times in the same scene, so that the sample size is increased, and the accuracy is improved. Meanwhile, because environmental sound information of different scenes is required, different scenes also need to be collected, and each scene collects a plurality of environmental sound samples. The scenes captured here should correspond to the scenes of the music recommendation list. The method for collecting the environmental sound is to call the sound collecting equipment or the sound collecting system of the intelligent terminal, capture the sound wave of the environment where the intelligent terminal is located, collect the environmental sound information of the environment where the intelligent terminal is located, avoid the intelligent terminal holder to send the sound of great loudness during collection, so as not to interfere collection, because the sound signal intensity of the nearest position of the sound collecting equipment can be far higher than the surrounding environment sound, and the weakening of the environmental sound is caused.
S102: extracting the same information in a plurality of environment sound information corresponding to the same scene to form standard environment sound information
After the environmental sound information is collected, a plurality of environmental sound information collected in the same scene need to be processed, and an audio information having the most characteristic of the scene is obtained as standard environmental sound information. The method for obtaining the audio information with the most scene characteristics can be to perform mean analysis on a plurality of environment sound information corresponding to the same scene to obtain the whole sound information of the scene, and can also extract a plurality of same information corresponding to the same scene in the environment sound information, the same information is the most audio information with the most scene characteristics, taking a subway as an example, the environment sound information collected on the subway has necessarily noisy human voice and booming voice of subway running, and human voice is different, but the booming voice of subway running is basically consistent, therefore, the basically same booming voice and different human voice of subway running can be separated from the environment sound information collected many times on the subway, the same information in the subway environment sound information collected many times is extracted here, namely the booming voice of subway running, and the audio information with the most scene characteristics on the subway is the sound of subway running, when a booming sound containing nearly uniform subway travel is detected in a certain sound, it can be considered to be on the subway. Therefore, the same information in the plurality of pieces of environmental sound information corresponding to the same scene is the audio information having the most characteristic of the scene, and the same information in the plurality of pieces of environmental sound information corresponding to the same scene may be extracted as the standard environmental sound information of the scene. When extracting, the environmental sound information needs to be converted from the analog signal into the digital signal, then the characteristic extraction and the filtering are carried out, so that the sound is separated, and the same audio information is obtained through a plurality of comparisons.
S103: acquiring a storage space in the intelligent terminal, and storing the standard environmental sound information into the storage space to form an environmental sound database
The method comprises the steps of extracting the same information in a plurality of environment sound information corresponding to the same scene, obtaining a storage space in an intelligent terminal after forming standard environment sound information, storing the standard environment sound information of each scene in the storage space to form an environment sound database, and storing the standard environment sound information and the scene names represented by the standard environment sound information in a one-to-one correspondence mode.
Referring to fig. 3, in a preferred embodiment, the step of collecting the current environmental sound information of the environment where the intelligent terminal is located specifically includes:
s301: calling a sound collection system of the intelligent terminal, and capturing a sound wave signal of the current environment where the intelligent terminal is located
After the environment sound database and the music recommendation list library are established, sound information of the current environment where the intelligent terminal is located needs to be collected, and current environment sound information is formed. The method comprises the steps of collecting sound information of the current environment of the intelligent terminal, calling a sound collection system of the intelligent terminal, and capturing sound wave signals of the current environment of the intelligent terminal through the sound collection system, wherein the collected recording system is a sound collection system and can be used for capturing the sound wave signals of the current environment of the intelligent terminal and collecting the sound information of the current environment.
S302: storing the sound wave signal in the intelligent terminal to form current environmental sound information
After the sound wave signal of the current environment where the intelligent terminal is located is captured and acquired, the sound wave signal needs to be stored in the intelligent terminal to form current environment sound information so as to carry out audio processing on the current environment sound information.
Referring to fig. 4, in a preferred embodiment, comparing the current environmental sound information with the standard environmental sound information, and when the current environmental sound information matches the standard environmental sound information, the step of pushing the music list associated with the scene corresponding to the standard environmental sound information in the music recommendation list library specifically includes:
s401: performing audio analysis on the environmental sound information, and extracting current audio features in the environmental sound information
After an environment sound database formed by standard environment sound information is established and current environment sound information of the intelligent terminal is collected, the current environment needs to be identified through comparison. Because the standard environmental sound information in the environmental sound database is processed audio information, in order to complete audio comparison, the current environmental sound information needs to be processed, the processing method is suitable for the processing method when the standard environmental sound information is obtained, if the standard environmental sound information is obtained, mean analysis is carried out on the current environmental sound information, multiple times of environmental sounds are collected in the current scene for mean analysis, if the standard environmental sound information is obtained, the same information in the standard environmental sound information is extracted as the audio information with the most characteristics of the scene, the processing method of the current environmental sound information suitable for the standard environmental sound information is to separate the current environmental sound information and separate the sounds emitted by different sound sources, no matter which audio analysis method, the tone color of each sound needs to be extracted finally, And audio features such as tone and loudness form the current audio feature.
S402: comparing the current audio features with standard audio features in the standard environmental sound information
After the current audio features of the current environmental sound information are obtained, audio features such as timbre, tone, loudness and the like in the standard environmental sound information also need to be extracted to form standard audio features, the current audio features are compared with the standard audio features in the standard environmental sound information, a comparison method is adapted to a processing method when the standard environmental sound information is obtained and a processing method of the current environmental sound information, a comparison method is integrated comparison when mean value analysis is carried out, when the standard environmental sound information is obtained, the same information in the standard environmental sound information is extracted to serve as the audio information with the most characteristics of the scene, the processing of the current environmental sound information adapted to the current environmental sound information is to separate the current environmental sound information to separate the sounds emitted by different sound sources, the matching method is a single comparison, which compares the sound emitted by different separated sound sources with the standard environmental sound. No matter what kind of comparison method is used for comparison, the audio characteristics such as tone, tone and loudness are compared.
S403: when the current audio features comprise the standard audio features, the current audio features are matched with the standard audio features, and a music list associated with a scene corresponding to the standard environmental sound information in the music recommendation list library is pushed
And after comparing the current audio features with the standard audio features in the standard environmental sound information, when the current audio features contain the standard audio features, considering that the current audio features are matched with the standard audio features. The standard of the current audio features including the standard audio features is that the current audio features identical to the standard audio features exist, the identical standard is mainly based on tone and tone, and the loudness is auxiliary. And if the current audio features are matched with the standard audio features, the current environment sound information is matched with the standard environment sound information, the scene where the intelligent terminal is located is a scene corresponding to the standard environment sound information, and a music list associated with the scene corresponding to the standard environment sound information is pushed according to the music recommendation list.
