These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
In the related art, a clipping control is usually manually dragged on an audio track to adjust a clipping position, and a specific position where the current clipping control is located is determined by playing an audio clip of an audio position where the clipping control is located, so as to determine an appropriate clipping position. The process needs to repeatedly listen to the audio clips and continuously adjust the cutting control to determine a proper cutting position, a large amount of time needs to be consumed, a user needs to frequently play the corresponding audio clips, the operation is very complicated, and the user experience is low.
In view of one or more of the above problems, exemplary embodiments of the present disclosure provide an audio clipping method, which may be applied to an audio clip synthesis scene, for example, matching a section of video with background audio, extracting a conference audio clip, making a ring tone, and the like, and may be deployed on an intelligent device such as a mobile phone, a tablet computer, and a desktop computer, and implement an audio clipping function by carrying a background program, thereby implementing interaction between a user interface and the background program.
It should be noted that, the above audio clipping method can not only clip pure audio, but also be applied to video clipping, and determine the audio position information to be clipped by using the above audio clipping technical means for the background audio of the video, and clip the video position corresponding to the audio position information based on the audio position information to be clipped, thereby achieving the clipping function for the video.
Fig. 1 shows a schematic flow of an audio clipping method in the present exemplary embodiment, including the following steps S110 to S140:
step S110, acquiring one or more search keywords of the audio to be cut;
step S120, matching the search keywords with a subtitle information base of the audio to be cut to determine one or more candidate audio segments;
step S130, determining a target audio clip from the candidate audio clips according to the user selection result;
and step S140, cutting the audio to be cut according to the position information of the target audio clip in the audio to be cut.
Above-mentioned audio frequency is tailor the in-process, confirms to tailor the position based on keyword matching, not only can pinpoint the position that needs were tailor, can also avoid the time consumption that the audio frequency of listening repeatedly brought, helps improving convenience and the efficiency that the audio frequency was tailor, and then promotes user operation and experiences.
Each step in fig. 1 will be described in detail below.
Step S110, one or more search keywords of the audio to be cut are obtained.
The audio to be cut refers to audio containing text information, and can be audio of songs, conference recording, movie and television dubbing and the like. The search keyword may be a keyword included in the audio segment where the position to be cut is located, and is used to locate the cutting position. The search keyword input by the user can be obtained from the search box of the user interface of the audio to be cut.
As shown in the user interface 200 of fig. 2, a user may enter a search keyword in text or speech form in a user interface search box 202, where 201 denotes an audio track representing a waveform of an audio signal.
In an alternative embodiment, the following steps S310 to S330 may be performed for audio segmentation before acquiring one or more search keywords of the audio to be clipped:
in step S310, the audio to be cut is divided into a plurality of audio segments.
Each audio clip is a segment of continuous audio in the audio to be clipped. The audio to be cut is automatically divided into a plurality of audio segments, and the duration of each audio segment can be the same or different.
In an alternative embodiment, the audio may be automatically segmented according to the silence gaps to divide the audio to be cut into a plurality of audio segments.
The mute interval here may be an interval in which no continuous text information appears. For example, when the audio to be cropped is a song, the audio may be segmented at the start position or the end position of each sentence of lyrics.
The silence gap may be identified by: when a part of the audio to be clipped in which no text information appears continuously exceeds a preset duration, the part can be recognized as a silent gap. For example, the threshold value of the silence gap may be set to 500 milliseconds, and a part of the audio to be clipped, in which no text information appears for 500 milliseconds continuously, is identified as the silence gap.
The audio is segmented based on the mute interval, the cutting operation habit of a user is met, and the positioning and cutting position are facilitated.
In step S320, the position information of each audio clip in the audio to be cut is recorded.
The position information here may contain the time points of the audio segments, the position information being relative to the entire audio to be cropped.
In an alternative embodiment, the position information of the audio segment in the audio to be cut includes any one or more of the following time points: a start time point of the audio segment and an end time point of the audio segment.
Step S330, the audio to be cut is recognized as character information and stored in a caption information base, and the character information carries the position information corresponding to the audio clip.
The text information may be obtained by speech recognition techniques, which convert audio information into text information. For example, when the audio to be clipped is a song, the text information may be lyric information; when the audio to be cut is conference recording, the text information can be conference speaking content; when the audio to be cut is the movie dubbing, the character information can be movie lines. The subtitle information library is used to store the identified text information. The text information carries position information corresponding to the audio segment, such as a start time point or an end time point of the audio segment.
It should be noted that the above mentioned time points are relative to the whole time axis of the audio to be clipped, and the time points are adopted to facilitate the fast and accurate positioning of the audio clips.
In the step shown in fig. 3, the audio to be cut is converted into text information, and the position information corresponding to the audio segment is carried, so that the search keywords are subsequently adopted for comparison, and the audio cutting position is determined from the audio to be cut.
And step S120, matching the search keywords with a subtitle information base of the audio to be cut so as to determine one or more candidate audio segments.
And comparing the search keywords with the text information stored in the caption information base of the audio to be cut to determine one or more candidate audio segments. Candidate audio segments refer to audio segments for the user to select a clipping location. The candidate audio segments may be fed back to the user interface for selection by the user.
In an alternative embodiment, matching the search keyword with the subtitle information base of the audio to be clipped to determine one or more candidate audio segments may be implemented by: matching the search keywords with a subtitle information base of the audio to be cut to determine one or more matched keywords; and determining the candidate audio clips according to the matched keywords.
The matching keywords are text information in the subtitle information base, and the matching keywords add partial context content relative to the search keywords. The audio clips corresponding to the matched keywords can be determined as candidate audio clips, and convenience is provided for a user to further judge the positions of the target audio clips.
As shown in the user interface 400 for inputting search keywords in fig. 4, when the keyword input by the user in the user interface search box 402 is "big lucky for cattle year", three related matching keywords, "congratulatory for your big lucky for cattle year", "big lucky for cattle year", and "big lucky for cattle year" are matched from the caption information base and displayed in the display box 403, and the user can determine the position of the target audio clip according to the displayed matching keywords.
In an alternative embodiment, the matching keyword carries position information corresponding to the candidate audio clip.
The position information corresponding to the candidate audio segment refers to the position information of the candidate audio segment in the whole audio to be clipped, and can be represented by the starting time point or the ending time point of the candidate audio segment in the whole audio to be clipped. The matching keywords carry the position information corresponding to the candidate audio clips, so that the user can identify and select the target audio clip from the candidate audio clips.
As shown in fig. 4, the time point of the occurrence of the matching keyword is also displayed in the display box 403 for the user to refer to, and the time point of the occurrence of the matching keyword may be the time point of the occurrence of the matching keyword in the audio to be clipped, or the time point corresponding to the position information of the candidate audio segment to which the matching keyword belongs.
Step S130, according to the user selection result, determining the target audio frequency segment from the candidate audio frequency segments.
The user selection result refers to a selection result made by the user for the candidate audio segment, and the candidate audio segment selected by the user is taken as the target audio segment. The target audio segment refers to an audio segment associated with the audio position to be clipped, and is selected by the user.
In the specific implementation process, the audio segment to which the matching keyword belongs can be used as a candidate audio segment, and the user selects the matching keyword to further determine the target audio segment, so that the function of selecting the target audio segment from the candidate audio segment is realized.
For example, when the user selects a matching keyword "niu-nian-gis" in fig. 4, the user interface changes, and as shown in fig. 5, a column of the matching keyword selected by the user, the corresponding audio cropping bar, and the cropping button above the corresponding audio cropping bar are displayed in bold.
It should be noted that, in the actual implementation process, the column of the matched keyword, the audio cropping bar, and the cropping button above the audio cropping bar selected by the user may also be displayed in a different manner, such as thickening, enlarging, or changing color, and the specific display effect may be set by the interface developer, which is not limited specifically here.
And step S140, cutting the audio to be cut according to the position information of the target audio clip in the audio to be cut.
When a clipping instruction sent by a user is received, the audio to be clipped can be clipped according to the position information of the target audio segment in the audio to be clipped, for example, the starting time point or the ending time point of the target audio segment.
The user may send a clipping instruction by clicking a clipping button in a column of the selected matching keyword in the user interface of fig. 5 or a clipping button above the corresponding audio clipping bar, clip the audio to be clipped, obtain the user interface shown in fig. 6, and divide the entire audio to be clipped into two.
It should be noted that, in the actual application process, the target audio segment may also be directly cut out through the cutting operation, that is, the target audio segment is cut out once respectively according to the start time point and the end time point of the target audio segment in the audio to be cut.
In an optional embodiment, the audio to be clipped is clipped according to the position information of the target audio segment in the audio to be clipped, and the following steps S710 to S730 shown in fig. 7 may be further implemented:
step S710, according to the position information of the candidate audio frequency segment in the audio frequency to be cut, the candidate cutting position is positioned.
The candidate clipping position here refers to a position where the candidate audio piece is located in the audio to be clipped. As shown in fig. 4, the position information of the audio clip to which the matching keyword belongs may be displayed in the form of audio crop bars at corresponding positions of the audio track 401, each audio crop bar representing one candidate crop position.
The user may select the position to be cropped as the target cropping position directly from the candidate positions, for example, directly from the cropping bar on the audio track of fig. 4, and the user interface shown in fig. 5 may also be obtained.
Further, the user can also determine the target clipping position by performing the following step S720.
Step S720, according to the position information of the target audio frequency segment in the audio frequency to be cut, the target cutting position is determined from the candidate cutting positions.
The target clipping position is one of the candidate clipping positions, and is automatically located from the candidate clipping positions according to the clipping position corresponding to the target audio segment selected by the user. The audio clip bar that is bolded on the audio track shown in fig. 5 can be considered as a target clip position.
And step S730, cutting the audio to be cut at the target cutting position.
The user can cut the audio to be cut by clicking the cutting button above the thickened audio cutting bar in the user interface of fig. 5, and the audio to be cut is divided into two parts.
In the step shown in fig. 7, by determining the target clipping position from the candidate clipping positions, the audio segment is associated with the clipping position, which is beneficial to presenting the candidate audio segment and the position of the target candidate segment in the whole audio to be clipped to the user in a global scope, so that the user can clip.
In an alternative embodiment, at the target clipping position, the audio to be clipped is clipped, and the audio can also be clipped by adjusting the clipping position as shown in fig. 8, which specifically includes the following steps S810 to S820:
step S810, receiving an adjustment instruction of a target clipping position on the audio track.
The user can adjust the target clipping position by sliding the audio clipping bar as shown in fig. 5, where the adjustment instruction may be a sliding operation performed by the user.
And step S820, cutting the audio to be cut according to the adjusting instruction.
After the target cutting position is determined, the cutting position can be finely adjusted in the step shown in fig. 8, so that the requirement of a user on more accurate cutting is met, and the cutting is more flexible and convenient.
