Referring to fig. 1a and 1b, fig. 1a is a scene schematic diagram of a method for controlling a karaoke song according to an embodiment of the present invention, and fig. 1b is a flowchart schematic diagram of the method for controlling the karaoke song according to the embodiment of the present invention; the Karaoke control method is applied to the vehicle-mounted terminal, can be executed by the vehicle-mounted terminal or a chip in the vehicle-mounted terminal, and comprises the following steps:

101, acquiring first K song audio data sent by a mobile terminal, wherein the first K song audio data are acquired by the mobile terminal and comprise accompaniment audio data and human voice audio data;

specifically, the user can utilize the mobile terminal to perform karaoke in a vehicle. The mobile terminal takes a mobile phone as an example, after the vehicular terminal starts a karaoke function, a user A can select a target song and a karaoke mode (modes such as playing accompaniment only or playing original singing audio only) after opening karaoke software on the mobile phone, and then click the song to play the karaoke. In the K song process, the mobile phone sends the first K song audio data collected by the mobile phone to the vehicle-mounted terminal at regular time, and the first K song audio data comprise the voice audio data of the user A and the corresponding accompaniment audio data. The length of the time interval of the timing acquisition may be set according to actual conditions, for example, set to 1 second, 3 seconds, 10 seconds, and the like, and is not particularly limited.

102, carrying out audio processing operation on the first Karaoke audio data to obtain second Karaoke audio data and human voice frequency data;

specifically, the vehicle-mounted terminal processes the first Karaoke audio data to obtain second Karaoke audio data and voice frequency data, wherein the voice quality of the second Karaoke audio data is superior to that of the first Karaoke audio data, and the voice frequency data refers to the singing frequency of a Karaoke singer and can be obtained by utilizing the first Karaoke audio data.

And 103, playing the second K song audio data, and controlling the vehicle-mounted atmosphere lamp to perform light response according to the human voice frequency data.

Specifically, the vehicle-mounted terminal uses a vehicle machine as an example, and after the vehicle machine obtains the second K song audio data, the vehicle machine controls a sound playing device on the vehicle, such as a loudspeaker, to play the second K song audio data, and controls the vehicle-mounted atmosphere lamp to perform light response according to the human voice frequency data. The number of the vehicle-mounted atmosphere lamps can be more than 1, and the vehicle-mounted atmosphere lamps can be surface lamps, line lamps, lighting lamps and the like.

The vehicle-mounted atmosphere lamp can be controlled to emit light directly according to the voice frequency data so as to respond to the singing voice of the K singer and improve the K singing experience; different human voice frequencies correspond to different light emitting brightness. Or determining the type of a target song singed by the K singer according to the voice frequency data to determine the response color of the vehicle-mounted atmosphere lamp; for example, when the song type is determined to be a music type with a gentle rhythm according to the human voice frequency data, the vehicle-mounted ambience lamp presents a blue main ambience; and when the song type is determined to be a music type with violent rhythm according to the voice frequency data, the vehicle-mounted atmosphere lamp presents red main atmosphere. Or, the light response of the K singing light can be carried out according to the voice frequency and the response color at the same time; finally, the mixed color output can be performed corresponding to red, green and blue according to the distribution characteristics of high, medium and low frequencies in the human voice frequency data.

By using the method, the mobile terminal is used as a microphone during the K song, so that no additional microphone is needed to be purchased or a highly-configured vehicle is not needed to be selected during the construction of the vehicle-mounted song-practicing room, and the vehicle-mounted K song cost is reduced; and the user is taken mobile terminal singing, not only possesses the ceremony sense of taking the microphone, still does not receive the constraint of position, in addition, the on-vehicle atmosphere lamp bakes the support, is favorable to improving user experience.

Further, determining the number of mobile terminals currently connected with the vehicle-mounted terminal; if the number is 1, for example, the first mobile terminal controls the vehicle-mounted ambience lamp to emit light according to the voice frequency data of the second karaoke audio data corresponding to the first mobile terminal. When the number of the connected mobile terminals is more than two, the vehicle-mounted atmosphere lamps are controlled to emit light respectively based on the second K song audio data corresponding to the mobile terminals, and if the mobile terminals are respectively the first mobile terminal, the second mobile terminal and the third mobile terminal and the number of the vehicle-mounted atmosphere lamps is 12, the 12 vehicle-mounted atmosphere lamps are divided into 3 groups, namely, a group A, a group B and a group C, and each group of the vehicle-mounted atmosphere lamps respectively serves one mobile terminal.

In the method, the display effect of the vehicle-mounted atmosphere lamps is determined according to the number of the connections of the mobile terminals, each K singer can be ensured to experience the K singing atmosphere brought by the atmosphere lamps, and the application range of the atmosphere lamps is favorably widened.

In one possible embodiment, before controlling the on-vehicle ambience light to perform the karaoke response, the method further comprises:

the vehicle-mounted terminal receives the response color of the vehicle-mounted atmosphere lamp sent by the mobile terminal, and controls the vehicle-mounted atmosphere lamp to perform karaoke response according to the received response color.

Specifically, the K singer may select a response color of the vehicle-mounted ambience light on the mobile terminal and send the selected response color to the vehicle-mounted terminal, or may send the response color selected by the user together when sending the first K song audio data. In this embodiment, can control the response light colour of on-vehicle atmosphere lamp according to user's response demand, further promote user's K song experience.

In a possible embodiment, in step 101, when the first K song audio data is obtained, and when the vehicle sound is noisy, the mobile terminal acquires the human voice audio data including the sounds of the plurality of users, and at this time, the vehicle-mounted terminal needs to process the human voice audio data including the sounds of the plurality of users. Specifically, the voice audio data sent by the mobile terminal is separated by using a blind source separation technology to obtain a plurality of voice audios respectively corresponding to a plurality of users. Then, the voice audio corresponding to the K singer is determined according to the amplitude of the voice audio, and the N personal voice audio with the amplitude larger than the amplitude threshold value is determined as the voice audio corresponding to the K singer, wherein when N is 1, the singing is carried out, and when N is more than 2, the singing is carried out in a song. Wherein, the specific numerical value of amplitude threshold value can set up according to actual need, because the distance of noise apart from the adapter equipment is great, results in the amplitude of noise less than, consequently, utilizes the amplitude size of sound can separate out K singer's voice audio frequency.

In a possible embodiment, in step 102, the audio processing operation is performed on the first karaoke audio data to obtain a second karaoke audio data, which specifically includes:

carrying out voice audio processing operation on the voice audio data to acquire target voice audio data; and carrying out audio synthesis operation on the target human voice audio data and the accompaniment audio data to obtain second K song audio data.

Specifically, the human voice audio processing operation includes, but is not limited to, at least one of noise reduction processing, echo cancellation processing, and audio amplification processing, so that the sound quality of the target human voice audio data obtained after processing is better than that of the human voice audio data before processing. When the voice audio data comprises more than 2 voices, voice audio processing is respectively carried out on the voice audio corresponding to each voice so as to obtain target voice audio data. And then carrying out audio synthesis operation on the accompaniment audio data and the target human voice audio data to obtain second K song audio data.

In one possible embodiment, the method further comprises:

and when the second K song audio data meet the preset conditions, modifying the human voice audio data according to the accompaniment audio data so as to update the second K song audio data.

Specifically, the preset conditions are used for determining the conditions of the K singer such as pronouncing, breaking, running and the like, when the K singer has the conditions, the vehicle-mounted atmosphere lamp cannot perform light response with the light effect expected by the K singer, and the K singing experience is reduced. Therefore, when the fact that the second K song audio data meet the preset conditions is determined, the vehicle-mounted terminal can modify the human voice audio data according to the accompaniment audio data to update the second K song audio data, play the updated second K song audio data, and control the vehicle-mounted atmosphere lamp to perform K song lamp light response according to the modified human voice audio data, so that the K song confidence of a user can be improved, and the K song response can be performed by ideal light of the user.

Further, the accompaniment audio and the original vocal audio of the target song have strong consistency, so that the human voice audio data can be corrected by utilizing the frequency spectrum rule of the accompaniment audio, specifically, when abnormal audio frequency points (break, pitch, etc.) existing in the human voice audio data are determined according to the frequency spectrum rule of the accompaniment and the frequency spectrum rule of the vocal audio data, audio point correction is carried out according to the frequency spectrum rule of the accompaniment, for example, the amplitude of the bass frequency points is reduced.

In a possible embodiment, referring to fig. 2, fig. 2 is a schematic flow chart illustrating a process of determining that second karaoke audio data meets a preset condition in the karaoke control method provided by the embodiment of the present invention, where determining that the second karaoke audio data meets the preset condition includes:

step 201, segmenting second K song audio data at preset intervals to obtain a plurality of second K song audio segments;

specifically, the method for determining that the second K song audio data meets the preset condition in this embodiment is described by taking the example that the second K song audio data contains the voice of one K singer, and when the second K song audio data contains the voice of more than two K singers, the processing method is the same as the processing method of one K singer.

First, the specific length of the preset interval may be periodic or aperiodic, and may be specifically set according to the actual situation, for example, the preset interval is set to 10ms, 30ms, 50ms, or 1s, etc. The second K song audio data are segmented according to preset intervals to obtain a plurality of second K song audio segments, and if the duration of the second K song audio data is 3min and the preset intervals are 1s, 180 second K song audio segments can be obtained.

Step 202, determining a first amplitude difference between the target human voice audio and the corresponding accompaniment audio in each second K song audio segment;

specifically, the unit of the intensity of the sound is "decibel", and the larger the value, the larger the sound, and the larger the amplitude. For each second K song audio pieces, a first amplitude difference between the target human voice audio and the corresponding accompaniment audio in the second K song audio pieces is determined, and a plurality of first amplitude differences, for example, 180 first amplitude differences, may be obtained.

Step 203, determining the weight corresponding to the second K song audio segment according to the occupation ratio of the voice in the second K song audio segment and a first preset corresponding relationship, wherein the first preset corresponding relationship is the corresponding relationship between the occupation ratio and the weight, and the larger the occupation ratio is, the smaller the weight is;

specifically, according to the proportion of the human voice in the corresponding second K song audio segments in each second K song audio segment, the weight corresponding to the second K song audio segments is determined according to the first preset corresponding relation. Wherein. The first preset corresponding relation may be set according to an actual situation, for example, table 1. The ratio can be calculated according to the total duration of the voice of the person in the second K song voice frequency section and the total duration of the second K song voice frequency section.

TABLE 1

Ratio of occupation of	Weight of
		0-10％	0.5
10％-50％	0.3
		50％-90％	0.15
90％-100％	0.05

Step 204, determining a second amplitude difference of the second K song audio data according to the first amplitude difference of the second K song audio segment and the corresponding weight;

specifically, a second amplitude difference of the second ktog audio data may be calculated according to each first amplitude difference and the corresponding weight, for example, assuming that there are first amplitude differences A, B and C and the corresponding weights are 0.05, 0.3 and 0.5, respectively, the second amplitude difference is 0.05A +0.3B + 0.5C.

In step 205, when the second amplitude difference is greater than the amplitude difference threshold, it is determined that the second kth-song audio data meets the preset condition.

Specifically, the specific value of the amplitude difference threshold may be set according to an actual situation, and when the second amplitude difference obtained in step 204 is greater than the amplitude difference threshold, it may be determined that the corresponding second K song audio data meets the preset condition, that is, the K singer has conditions of missing sound, breaking sound, running tone, and the like.

It is particularly noted that the step numbers in fig. 2 are only used to distinguish different steps, and the execution sequence between the steps is not limited. For example, the first amplitude difference and the weight may be determined simultaneously, or the weight may be determined first and then the first amplitude difference, or the first amplitude difference may be determined first and then the weight may be determined.

In one possible embodiment, the karaoke control method further comprises the following steps:

determining the age of the K singer according to the voice audio data; determining the corresponding response color of the atmosphere lamp according to the age of the K singer and a second preset corresponding relationship, wherein the second preset corresponding relationship is the corresponding relationship between the age and the lighting color of the atmosphere lamp; and controlling the vehicle-mounted atmosphere lamp to respond according to the response color.

Specifically, based on the voice audio data collected by the mobile terminal, an age prediction process may be performed, for example, using an age identification model to determine the age of the K singers, taking the case where the voice audio data includes 1K singer as an example. Then, the response color of the corresponding vehicle-mounted atmosphere lamp can be determined according to the predicted age and the second preset corresponding relation. The second preset corresponding relationship may be set according to an actual situation, for example, as shown in table 2. And finally, controlling the vehicle-mounted atmosphere lamp to respond to the K song according to the determined response color. When the voice audio data includes more than 2K singers, the response color is determined according to the number of K singers corresponding to the same response color, for example, if there are 4 chorus players, where 2 chorus players correspond to the response color green, 1 chorus player corresponds to the color blue, and 1 chorus player corresponds to the color purple, green is used as the response color. When more than 2 singers correspond to different response colors, the response color corresponding to the singer with the smallest age or the singer with the largest age can be used as the final response color. In the case of 2 or more K singers, the method of determining the response color may be other methods, and is not particularly limited.

TABLE 2

Age range/year	Response color
		0-10	Pink colour
10-25	Green colour
		25-45	Blue color
45-60	Purple color
		More than 60	Yellow colour

In a possible embodiment, referring to fig. 1a and fig. 3, fig. 3 is a schematic flow chart of recommending songs in a method for controlling K songs provided in an embodiment of the present invention, where the method for controlling K songs further includes:

step 301, determining the tone type of a K singer and the song type of a K song according to the voice audio data;

specifically, the voice type of the K singer can be identified by using voice audio data and a pre-trained tone identification model; in addition, the song type of the K song is predicted by utilizing the human voice audio data and the pre-trained song type recognition model, and the song type is determined as the favorite song type of the K singer. Wherein, the tone color types comprise six categories of male voice hoarseness, male voice brightness, female voice hoarseness, female voice brightness, sweet and soul, exemplarily; and the types of songs include classical music, pop music, blues, rock, jazz, orchestra, and modern music.

In particular, the target vocal audio data may also be employed to determine the timbre type of the K singer and the song type of the K song.

Step 302, determining a recommended song according to the tone type and the song type;

specifically, the recommended song of the K singer is determined by combining the tone type and the song type of the K singer song, so that the song suitable for the K singer to sing can be more accurately positioned, and the K singing experience is improved. The recommended song determined at this time should be understood as a song that suits the tone of the K singer and is the favorite song type of the K singer.

Step 303, sending the recommended song to the mobile terminal.

Specifically, the vehicle-mounted terminal sends the recommended songs to the mobile terminal, so that a K singer can select and determine target songs of the K singing from the recommended songs, the operation required for the K singer to search for the singing songs is reduced, and the K singing experience of a user is improved.

and when the mobile terminal determines that the current prompt mode is the ringing mode, automatically switching the prompt mode to a mute mode or a vibration mode.

Specifically, when the mobile terminal detects that the current prompt mode is the ringing mode, in order to avoid or reduce interference of the information prompt tone to the sound collection of the K singer, the mobile terminal automatically switches the prompt mode to the mute mode or the vibration mode, and the K singing experience is optimized.

It is worth pointing out that the vehicle-mounted ambience lamp referred to in the above method is an ambience lamp installed inside a vehicle.

In a possible embodiment, it is determined that the vehicle-mounted terminal is performing karaoke control, and when the vehicle-mounted terminal detects that someone or a vehicle (such as a motor vehicle or a non-motor vehicle) enters a preset range around the vehicle where the vehicle-mounted terminal is located (the preset range can be adjusted according to actual conditions such as a circular range with the vehicle as a circle center and a radius of 2 meters), the vehicle-mounted terminal suspends karaoke control, namely, stops playing second karaoke audio data and light response in the suspended vehicle, and plays a pre-stored danger prompt tone, so as to perform danger prompt on a driver of the vehicle, and ensure driving safety. When no person or vehicle is detected to enter the preset range, the vehicle-mounted terminal continues to perform Karaoke control, namely, continues to play the second Karaoke audio data and continues to perform lamplight response in the vehicle.

Further, the method for determining the danger level of the person or the vehicle entering the preset range comprises the following steps: the action speed v and the action acceleration a of the person or the vehicle are determined, and the risk score W is determined based on the action speed and the action acceleration. Where W ═ Av + Ba, A, B are weights corresponding to the action speed and the action acceleration, respectively, the sum of a and B is 1, and the specific value of A, B may be set according to the actual situation, for example, a is 0.4 and B is 0.6; alternatively, A, B were all 0.5. And then, dividing the risk score into different risk levels according to the risk score, a first risk score threshold value and a second risk score threshold value, wherein the first risk score threshold value is smaller than the second risk score threshold value, and specific numerical values of the first risk score threshold value and the second risk score threshold value can be set according to actual conditions. The risk score is smaller than the first risk score threshold value and is a third risk level; the risk score is greater than or equal to the first risk score threshold, but is smaller than the second risk score threshold to form a second risk level; the danger score is greater than or equal to the second danger score threshold and is the first danger level.

Optionally, the vehicle-mounted terminal may pause the second K song audio data and pause the light response when determining that the risk level of the person or the vehicle entering the preset range is the first risk level in the K song process, and play the danger prompt tone, and simultaneously control a vibrator (such as a motor) in the mobile terminal that is using the K song to generate vibration, so as to remind the user that is using the mobile terminal to perform the K song of paying attention to the dangerous situation. And when the danger level of the person or the vehicle entering the preset range is determined to be a second danger level, pausing the second K song audio data and pausing the light response. And when the danger level of the person or the vehicle entering the preset range is determined to be a third danger level, the second Karaoke audio data is not controlled to be paused, and the light response is not controlled to be paused.

Based on the foregoing embodiment of the method for controlling karaoke songs applied to a vehicle-mounted terminal, an embodiment of the present invention further provides a method for controlling karaoke songs, which is applied to a mobile terminal and can be executed by the mobile terminal itself or a chip in the mobile terminal, and referring to fig. 4, fig. 4 is a schematic flow diagram of another method for controlling karaoke songs provided by an embodiment of the present invention; the method comprises the following steps:
