The tone color can be the tone color in the tone color market of the electronic equipment, that is, the electronic equipment can actively recommend the tone color meeting the user requirement in the tone color market to the user, so that the utilization rate of the tone color market is improved, and the product availability is high.

The tone market can maintain watermarks of a plurality of tone colors, any tone color watermark can identify the tone color, and watermarks of different tone colors can be different. For any one tone, the watermark for that tone may be extracted from the audio of that tone.

In one embodiment, after the electronic device displays the first information indicating the first tone, the electronic device may continue to play the first audio and video, and at this time, a third interface may be displayed, and the electronic device may display the first identifier in the third interface, where the third interface does not include the first information. In some examples, the first interface and the third interface are both used to play the first audio-video, but the time point of play is different, e.g., the time point of play of the first interface is earlier than the time point of play of the third interface. In some examples, after the electronic device obtains the first tone, the electronic device may display the first information in the playing interface of the first audio and video between the current time and a time after a preset second time, and after the preset second time, the electronic device may cancel displaying the first information and display the first identifier in the playing interface of the first audio and video.

In one embodiment, the first identifier may be located at a position of a third time point in the playing progress bar of the first audio and video, where the third time point is related to a time point when the first tone is acquired, in some examples, the third time point is any time point in the first audio, for example, the first time point or the second time point, in other examples, the third time point is a time point when the electronic device receives the first operation for the first control in the first interface, and may also be understood as a time point when the tone recommendation function is turned on, in other examples, the third time point is a time point when the electronic device displays the first information indicating the first tone, where the specific time point of the third time point is not limited, but is later than a starting time point of the first audio and video and a time point earlier than a time point when the electronic device displays the first information indicating the first tone.

The order of S115, S113, and S114 is not limited, for example, after S113, the electronic device may return to the playing interface for displaying the first audio and video in response to the operation on the second interface, and then display the first identifier in the playing interface for the first audio and video.

S116: the electronic device displays first information in response to an operation acting on the first identifier.

S116 is an optional step.

In one embodiment, the electronic device may display first information indicating the first tone color in the third interface in response to the operation for the first identification in the third interface, and the display manner of the first information may be described in S109.

Not limited to the embodiment shown in fig. 3, in another embodiment, when the electronic device determines that the watermark in the voice section cannot be extracted, the electronic device may also prompt the user for failure of tone color recommendation, for example, S110-S112 are not performed, but S105 is performed.

The operations in the present application may be, but not limited to, touch operations, gestures, voice inputs, brain waves, etc., and the present application is not limited to the specific form of the operations.

In the method shown in fig. 3, when the user finds that the favorite tone color appears in the first audio and video played by the electronic device, the first operation can be performed, the electronic device can acquire the tone color of the voice in the first audio and video according to the first operation, or the tone color similar to the tone color of the voice in the first audio and video and recommend the tone color to the user, the user can browse, purchase, download and use the recommended tone color, and the recommended tone color can be the tone color in the tone color market, so that the user can conveniently and quickly acquire the favorite tone color without manually searching in the tone color market (corresponding to the mode one), the operation is reduced, and compared with searching for the tone color through the keyword search (corresponding to the mode one), the recommended tone color is more accurate, the user requirement is effectively met, and the use ratio of the tone color market is also improved.

And if the first information is not operated in the second duration of the user, or after the user looks up the information of the first tone through the first information, the electronic device can cancel to display the first information and display the first identifier, and the user can look up the first information again through operating the first identifier, so that the first information is prevented from affecting the user to watch the first audio and video, and even if the user subsequently wants to look up the information of the first tone again, the user does not need to manually adjust the playing time point of the first audio and video to the time point of executing the first operation before, then execute the first operation again, reduce the operation, and improve the user experience, thereby further improving the use ratio of the tone market.

An application scenario and a user interface embodiment under the scenario according to the embodiment of the present application are described below. The following embodiment will be described taking the electronic device 100 as an example to turn off the tone color recommending function by default.

The user interface 610 may include a play box 611 (in which a title 612 is displayed, the title 612 including the character "video 1"), a play control 613, a video progress bar 614, a play progress bar 615, duration information 616, and a control 617, wherein the play box 611 may be used to play a video named "video 1" (hereinafter referred to simply as video 1). The play control 613 may be used to pause or play the currently playing video 1. The video progress bar 614 may indicate the overall progress of video 1 and the play progress bar 615 may indicate the progress of the video that is currently being played. The duration information 616 may include a total duration of the video 1 (corresponding to the video progress bar 614) and a currently played duration (corresponding to the play progress bar 615), for example, "11:28/48:52", where "48:52" may indicate that the total duration of the video 1 is 48 minutes and 52 seconds, "11:28" may indicate that the currently played duration is 11 minutes and 28 seconds, and may also indicate that the current playing time point is 11 minutes and 28 seconds in the video 1, that is, the image displayed by the play frame 611 is an image of 11 minutes and 28 seconds in the video 1. When the electronic device 100 plays the video 1 normally, the time length information 616 will increase the time length that has been played currently, and the playing progress bar 615 will also be lengthened. The character "timbre recommendation" may be displayed next to control 617, control 617 may be used to trigger the opening or closing of the timbre recommendation function, and control 617 shown in user interface 610 may characterize that the timbre recommendation function has been closed. In some examples, displaying user interface 610 by electronic device 100 may perform S101 shown in fig. 3 for electronic device 100, where video 1 is the first audio-video described in fig. 3 and control 617 is the first control described in fig. 3.

In one implementation, electronic device 100 may turn on the tone color recommendation function in response to an operation acting on control 617 (e.g., the operation is a touch operation, such as a click operation), in some examples, when electronic device 100 performs S102 shown in fig. 3, it may be determined that the tone color recommendation function has been turned on. Moreover, in response to the operation on the control 617, the electronic device 100 may acquire a tone color of a voice in the audio 1 from a time point (11 minutes and 28 seconds) currently played in the video 1 to a time point (for example, the first time period is 1 minute and the time point is 12 minutes and 28 seconds) after a preset first time period, or a tone color similar to the tone color of the voice in the audio 1, where the acquired tone color may be referred to as tone color 1, and in some examples, the acquiring process may be performed for the electronic device 100 by S102-S108 and S110-S111 shown in fig. 3, where the audio 1 is the first audio described in fig. 3, the 11 minutes and 28 seconds is the first time point described in fig. 3, the first time period is 1 minute and the 12 minutes and 28 seconds is the second time point described in fig. 3, and the tone color 1 is the first tone color or the second tone color described in fig. 3. After the electronic device 100 turns on the tone color recommendation function, a user interface 620 shown in fig. 6 (B), which is illustrated in fig. 6 (B) by taking the electronic device 100 as an example of acquiring the tone color 1.
