Embodiment of the method

Multimedia file is played back, is generally played back based on media file library.The foundation in media file library Method is as follows: the multimedia files such as obtained voice or video will be recorded and mark off multiple media fragments, it can be in short It is divided, can also be divided as unit of the continuous one section of word of role a certain in media file for unit.Then, it utilizes The method of speech recognition carries out speech recognition to the media fragment marked off, identifies the text corresponding to each media fragment Segment.The corresponding relationship between text segment and media fragment is established, and the corresponding relationship is stored into media file library.

As shown in fig. 7, being the flow chart of multimedia file back method provided in an embodiment of the present invention, including following step It is rapid:

Step 701: in response to the selection operation to target text segment, triggering the playback request to multimedia file.

Resulting text information after display multimedia file conversion, chooses a certain text segment, base in the text information In the selection operation to the target text segment, the playback to multimedia file is triggered, at this point, the letter plate section is target text Word slice section.

In one example, as shown in Fig. 2, resulting text is believed after showing multimedia file conversion on user interface Breath, a text segment correspond to a broadcasting button.The corresponding broadcasting button of a text segment is triggered, is realized to the text The selection operation of segment, the letter plate section are to be chosen as target text segment, and triggering is based on the corresponding text of the broadcasting button Segment executes the playback to multimedia file.

Such as: clicking text segment, " court debate and court investigation are combined together progress, and it is different whether different parties have The corresponding broadcasting button of view ", " court debate and court investigation are combined together progress to text segment, and whether different parties have Objection " is chosen as target text segment, triggering based on text segment " court debate and court investigation are combined together progress, Whether different parties have objection " multimedia file playback.

In another example, as shown in figure 3, it is resulting after multimedia file conversion shown on user interface Text information, multiple text segments are shown as a whole.Can by cursor is moved in text information one In a text segment, to realize the selection operation to the letter plate section, at this point, the letter plate section is as target text segment, touching Hair is based on the corresponding text segment of the broadcasting button, executes the playback to multimedia file.

Step 702: inquiring the media file library, search the corresponding target medium segment of the target text segment.

Step 703: the multimedia file being played back according to the target medium segment.

According to the establishment process in above-mentioned media file library it is found that including text segment and media fragment in media file library Between corresponding relationship.In step 701, after the playback request for triggering the multimedia file based on target text segment, from The corresponding media fragment of target text segment is searched in the media file library, using the media fragment as target medium segment.

After finding the corresponding target medium segment of target text segment, based on the target text segment to multimedia file It is played back, that is, is based on the corresponding target medium segment of the target text segment, multimedia file is played back.According to being touched The playback request to multimedia file of hair can choose the only corresponding target medium segment of playback target text segment, into Playback of the row to multimedia file；Also it can choose using target medium segment as starting point, it is more after playing back the target medium segment A media fragment, to realize the playback to multimedia file.

In order to facilitate understanding, now above-mentioned steps are carried out detailed for example:

" the small icon function of testing right side " is chosen as target text segment, in media file library, according to matchmaker Corresponding relationship between the text segment saved in body library and media fragment is searched, and the target text segment is found " the small icon function of testing right side " corresponding target medium segment.The playback of multimedia file is asked according to what is triggered It asks, multimedia player can be used, it is corresponding directly to play target text segment " the small icon function of testing right side " Target medium segment realizes the playback to multimedia file；Also multimedia player can be used, play target text segment Multiple media fragments after " the small icon function of testing right side " corresponding target medium segment, and then realize to more matchmakers The playback of body file.

The method played back using above-mentioned multimedia file, can be quickly found corresponding media piece according to text segment Section, in turn, plays back multimedia file based on the media fragment found according to the playback request triggered.It greatlys save Time of user.

After selection target text segment, the playback request to multimedia file can be triggered, in the present embodiment, introduces choosing After middle target text segment, trigger using the corresponding target medium segment of target text segment as the playback request of content, to more matchmakers The specific implementation method that body file is played back.As shown in figure 8, being the corresponding method flow diagram of the embodiment of the present invention.

Step 801: in response to the selection operation to target text segment, triggering with the corresponding target matchmaker of target text segment Body segment is the playback request of content.

Step 802: inquiring the media file library, search the corresponding target medium segment of the target text segment.

Step 803: obtaining the corresponding target medium segment of the target text segment, play the target medium piece Section.

To the selection operation of target text segment, method described in step 701 in specific implementation and embodiment one Similar, content described in reference 701, which is not described herein again.

After selected target text segment, as shown in Figures 2 and 3, show that the Option Box of playback mode, the Option Box provide The option of two kinds of playback modes, one is " playing " from current character segment, i.e., with the corresponding target medium of target text segment Segment is starting point, is played back to multimedia file；Another kind is " playing current character segment ", as with target text segment Corresponding target medium segment is content, plays back to multimedia file, i.e., only plays back the corresponding mesh of target text segment Mark media fragment.In the present embodiment, the playback mode of selection " playing current character segment " triggers the playback to multimedia file Request, the playback request are using the corresponding target medium segment of target text segment as the playback request of content.

Media file library is searched, according to the corresponding pass between the text segment stored in media file library and media fragment System finds the selected corresponding target medium segment of target text segment.Since the playback request triggered is with target text The corresponding target medium segment of segment is the playback request of content, i.e., carries out to the corresponding target medium segment of target text segment Playback, therefore, after getting the corresponding target medium segment of target text segment, multimedia player directly plays back the target Media fragment can be realized using the corresponding target medium segment of target text segment as content, play back to multimedia file.

The corresponding text information of court's trial media file that will be played back extracts in court's trial notes content display area, As shown in figure 3, to be played back to " the small icon function of testing right side " the corresponding media fragment of text segment, i.e., will " the small icon function of testing right side " is chosen for target text segment.Cursor of mouse is moved to and " is tested on the right side of In small icon function " text segment, at this point, " the small icon function of testing right side " corresponding background is in be highlighted, it is single Left mouse button is hit, shows the Option Box of playback mode, user clicks " playing current character segment ", that is, can trigger with the target The corresponding target medium segment of text segment " the small icon function of testing right side " is content, is returned to multimedia file The playback request put plays back the corresponding target medium piece of target text segment " the small icon function of testing right side " Section.

In media file library, according to media file library save text segment and media fragment between corresponding relationship, Search the corresponding target medium segment of target text segment " the small icon function of testing right side ".By the playback triggered Request is played back to the corresponding target medium segment of target text segment " the small icon function of testing right side ", because This can directly pass through multimedia player after getting target medium segment, play target text segment " one lower right of test The corresponding target medium segment of the small icon function of side " realizes the playback to the multimedia file.

Multimedia file is played back using method provided in this embodiment, can be quickly found corresponding to target text The target medium segment of word slice section, and then directly play the target medium segment.It is easy to operate, save the time.

In above-described embodiment, describe using the corresponding target medium segment of target text segment as content, to multimedia text Part is played back.In the present embodiment, introduce using the corresponding target medium segment of target text segment as starting point, to multimedia file In the specific implementation method that is played back of content after the target medium segment.As shown in figure 9, corresponding for the embodiment of the present invention Method flow diagram.

Step 901: in response to the selection operation to target text segment, triggering with the corresponding target matchmaker of target text segment Body segment is the playback request of starting point.

Step 902: from the media file library, according to putting in order for the media fragment, obtaining the target matchmaker Body segment and the media fragment to put in order after the target medium segment and playback.

Based on the method for building up in media file library shown in Fig. 7, in the present embodiment, in established media file library, also Store putting in order for media fragment.Concrete methods of realizing is as follows:

When establishing media file library, the multimedia files such as obtained voice or video will be recorded and mark off multiple media Segment can be divided as unit of a word, can also be as unit of the continuous one section of word of role a certain in media file It is divided.The media file fragments marked off are arranged by the sequencing of play time, i.e., play time is preceding Putting in order for media fragment is also forward, and the posterior media fragment of play time puts in order also rearward, and by media fragment Put in order and be stored in media file library.It is of course also possible in media file library, it is suitable according to the arrangement of media fragment Sequence further sets gradually arrangement serial number for media fragment, and the corresponding relationship for arranging serial number and media fragment is stored to media In library.

In order to facilitate understanding, now the method for building up in media file library is carried out detailed for example:

Broadcasting of the corresponding media fragment of text segment " the small icon function of testing right side " in multimedia file Time is 1 second to 4 seconds, and play time of the corresponding media fragment of text segment " too small " in multimedia file is 4 seconds To 5 seconds, play time of the corresponding media fragment of text segment " perhaps, what in the event of that " in multimedia file It is 5 seconds to 8 seconds, according to play time of the above-mentioned media fragment in multimedia file, each media fragment is subjected to first heel row Sequence.The corresponding media fragment of text segment " the small icon function of testing right side " is as the first media fragment, text segment For " too small " corresponding media fragment as the second media fragment, text segment " perhaps, what in the event of that " is right The media fragment answered is as third media fragment, according to the first media fragment, the second media fragment and third media fragment Sequence is arranged.And so on, resulting media fragment is successively ranked up according to the method described above, obtained arrangement is suitable Sequence is stored into media file library.

Certainly, for convenience, can also putting in order according to media fragment, be each media fragment according to the suitable of arrangement The corresponding arrangement serial number of sequence setting, the as corresponding media fragment setting of text segment " the small icon function of testing right side " Serial number 1 is that serial number 2 is arranged in text segment " too small " corresponding media fragment, be text segment " perhaps, in the event of That what " serial number 3 is arranged in corresponding media fragment, and so on, and the corresponding relationship for arranging serial number and media fragment is deposited Storage is into media file library.

In practical applications, media fragment is ranked up, and saves the putting in order to media file library of media fragment Operation, can carry out, can also be carried out after speech recognition media fragment, herein not before speech recognition media fragment Do any restriction.

The search operation of selection operation and target medium segment for target text segment, specific implementation and reality It is similar with the method described in step 702 to apply step 701 in example one, the content with reference to described in 701 and 702 is no longer superfluous here It states.

After selected target text segment, as shown in Figures 2 and 3, show that the Option Box of playback mode, the Option Box provide The option of two kinds of playback modes, one is " playing " from current character segment, i.e., with the corresponding media fragment of target text segment It is played back for starting point；Another kind is " playing current character segment ", is as with the corresponding media fragment of target text segment Content is played back, i.e., only plays back the corresponding media fragment of target text segment.In the present embodiment, select " from current character The playback mode of segment broadcasting ", triggers the playback request to multimedia file, which is with the target text segment pair The target medium segment answered is starting point, and in multimedia file, all the elements after the target medium segment are played back.

In order to realize using the corresponding target medium segment of the target text segment as starting point, in multimedia file, to this All the elements after target medium segment and the target medium segment are played back, and there are a variety of possible implementations.

The first implementation obtains target medium according to putting in order for the media fragment stored in media file library Segment, and the media fragment after target medium segment that puts in order；Get above-mentioned target medium segment, and arrangement Sequence is after the media fragment after target medium segment, according still further to putting in order for each media fragment, successively to target matchmaker Body segment, and the media fragment to put in order after target medium segment play out.

Second of implementation, according to putting in order for the media fragment stored in media file library, with target medium piece Section be starting point, every time only obtain a media fragment, after being finished to the media fragment, then obtain another media fragment into Row plays.For example, acquisition is adjacent with the target medium segment, and is arranged in the target after finishing to target medium segment Media fragment M1 after media fragment；After being finished to media fragment M1, then obtain it is adjacent with media fragment M1, and Media fragment M2 after being arranged in media fragment M1；After being finished to media fragment M2, then obtain and the media fragment M2 is adjacent, and is arranged in the media fragment M3 after media fragment M2, and so on, to being arranged in after target medium segment Multiple media fragments successively play out, and stop playing up to user triggers, or be arranged in target medium segment and own later Media fragment finish.

The corresponding text information of court's trial media file that will be played back extracts in court's trial notes content display area, Target text segment is selected according to the implementation method in previous embodiment, with " the small icon function of testing right side " As target text segment, " the small icon function of testing right side " target text segment is carried out by single left button mouse click Selection is clicked " playing from current character segment " button, that is, be can trigger with the target text segment pair in the Option Box of pop-up The target medium segment answered is starting point, in multimedia file, what all the elements after the target medium segment were played back Playback request.

System receives and includes the playback request of " the small icon function of testing right side ", and identifies that the playback is asked It asks to be played back to the content after target medium segment using the corresponding target medium segment of target text segment as starting point Playback request, according to the corresponding relationship saved between text segment and media fragment, obtains target text in media file library The corresponding target medium segment of segment " the small icon function of testing right side ".Next, according to being saved in media file library Media fragment put in order, successively obtain the corresponding media of target text segment " the small icon function of testing right side " Media fragment after segment first obtains text segment " too small " corresponding media fragment, then obtain text segment " or Perhaps, in the event of that " corresponding media fragment, until having obtained all media fragments.And the target that will acquire The corresponding target medium segment of text segment " the small icon function of testing right side ", text segment " too small " are corresponding The corresponding media fragment of media fragment and text segment " perhaps, what in the event of that ", and all letter plates later The corresponding media fragment of section correspondingly puts in order according to what is stored in media file library, plays in order target text segment " the small icon function of testing right side " corresponding target medium segment, the corresponding media piece of text segment " too small " Section, the corresponding media fragment of text segment " perhaps, what in the event of that " and all text segments are corresponding later Media fragment, realization are with the corresponding target medium segment of target text segment " the small icon function of testing right side " Point plays back all media fragments later in multimedia file.

It can also be with target text segment " the small icon function of testing right side " for starting point, to target text piece After the corresponding target medium segment of section " the small icon function of testing right side " finishes, saved according in media file library Media fragment put in order, obtain target matchmaker corresponding with target text segment " testing the small icon function on the right side of " Body segment is adjacent, and is arranged in the media fragment after the target medium segment, i.e. acquisition text segment " too small " is right The media fragment answered；After being finished to the corresponding media fragment of text segment " too small ", then obtain with text segment " too It is small " corresponding media fragment is adjacent, and is arranged in the media fragment after the media fragment, that is, obtain text segment " perhaps, In the event of that " corresponding media fragment, matchmaker corresponding to text segment " perhaps, what in the event of that " Body segment plays out, and so on, to target text segment " the small icon function of testing right side ", and it is arranged in mesh Multiple media fragments after the corresponding target medium segment of mark text segment " the small icon function of testing right side ", successively It plays out, stops playing until user triggers, or all media fragments being arranged in after target medium segment play Finish.

Multimedia file is played back using method provided in this embodiment, can quick and precisely find target text piece The corresponding target medium segment of section, and put in order according to the media fragment in media file library, after target medium segment Media fragment successively plays out, to realize to multimedia playback.The time of user is greatly saved.

In the present embodiment, the method for building up based on different media file libraries is introduced corresponding with target text segment Target medium segment is starting point, the specific embodiment party played back to the content after the target medium segment in multimedia file Method.It as shown in Figure 10, is the corresponding method flow diagram of the embodiment of the present invention.

Step 1001: in response to the selection operation to target text segment, triggering with the corresponding target of target text segment Media fragment is the playback request of starting point.

Step 1002: from the media file library, according to the sequencing of the corresponding play time of the media fragment, Obtain the media fragment played after the target medium segment and the target medium segment and playback.

Based on the method for building up in media file library described in embodiment one, in the present embodiment, in established media text In part library, the corresponding relationship of media fragment and play time is also stored.Concrete methods of realizing is as follows:

When establishing media file library, the multimedia files such as obtained voice or video will be recorded and mark off multiple media Segment, records play time of each media fragment in multimedia file, which includes the media fragment in more matchmakers Starting playing time and termination playing time in body file, and the corresponding relationship of media fragment and play time is stored in matchmaker In body library.

Broadcasting of the corresponding media fragment of text segment " the small icon function of testing right side " in multimedia file Time is 1 second to 4 seconds, i.e., the starting playing time of the media fragment is 1 second, and terminating playing time is 4 seconds；Text segment is " too It is small " play time of corresponding media fragment in multimedia file is 4 seconds to 5 seconds, i.e. the starting of the media fragment is broadcast Put is 4 seconds constantly, and terminating playing time is 5 seconds；The corresponding media fragment of text segment " perhaps, what in the event of that " Play time in multimedia file is 5 seconds to 8 seconds, i.e., the starting playing time of the media fragment is 5 seconds, when terminating broadcasting Carve is 8 seconds.According to the method described above, play time of the media fragment in multimedia file is obtained, play time includes that starting is broadcast It puts the moment and terminates playing time, and the corresponding relationship of media fragment and play time is stored into media file library.

In practical applications, the corresponding play time of preservation media fragment, can be in speech recognition matchmaker to media file library It is carried out before body segment, can also be carried out after speech recognition media fragment, not do any restriction herein.

After selected target text segment, as shown in Figures 2 and 3, show that the Option Box of playback mode, the Option Box provide The option of two kinds of playback modes, one is " playing " from current character segment, i.e., with the corresponding media fragment of target text segment It is played back for starting point；Another kind is " playing current character segment ", is as with the corresponding media fragment of target text segment Content is played back, i.e., only plays back the corresponding media fragment of target text segment.In the present embodiment, select " from current character The playback mode of segment broadcasting ", triggers the playback request to multimedia file, which is with the target text segment pair The target medium segment answered is starting point, in multimedia file, what all the elements after the target medium segment were played back Request.

Similar with embodiment three, the present embodiment is with the corresponding target medium segment of the target text segment in order to realize Starting point plays back all the elements after the target medium segment and the target medium segment in multimedia file, There is also a variety of possible implementations.

The first implementation in media file library, further obtains target matchmaker after getting target medium segment Play time of the body segment in multimedia file.According to the corresponding play time of the media fragment stored in media file library, Obtain all media fragments of the play time after the corresponding play time of target medium segment.It is deposited according in media file library The play time of each media fragment of storage, to the target medium segment and play time got in target medium segment Media fragment later is successively played out according to play time sequencing.

Second of implementation, using target medium segment as starting point, according to the corresponding play time of media fragment, acquisition is broadcast The adjacent media fragment of time play time corresponding with target text segment is put, which is played out, just to this In the playback progress of the media fragment of broadcasting, the difference terminated between playing time corresponding with the media fragment is less than a certain When preset threshold, the adjacent next media fragment of play time corresponding with the media fragment is obtained, and to next media Segment is buffered, and when media fragment being played on is played to the termination playing time of the segment, is directly played next Media fragment.According to the method described above, a media fragment is only obtained every time, after the media fragment finishes, is directly played Next media fragment, until the closing playback that all media fragments after target medium segment finished or received user refers to It enables.

For example, work as the playback progress of target medium segment, the difference between the termination playing time of target medium segment, When less than above-mentioned preset threshold, according to the corresponding play time of target medium segment, in media file library, play time is searched The adjacent media fragment N1 of play time corresponding with target medium segment, i.e., when being played according to the termination of target medium segment It carves, in media file library, finds starting playing time media fragment identical with the termination playing time of target medium segment N1, and media fragment N1 is buffered；To the end of target medium segment plays, directly broadcasting media fragment N1；Correspondingly, to The playback progress of media fragment N1, when termination playing time corresponding with media fragment N1 is less than above-mentioned preset threshold, then According to the method described above, the adjacent media fragment N2 of play time play time corresponding with media fragment N1 is obtained, and to matchmaker Body segment N2 is buffered, after media fragment N1 is finished, directly broadcasting media fragment N2, and so on, when to playing Between all media fragments after the corresponding play time of target medium segment successively play out, stop until user triggers All media fragments of broadcasting or play time after the corresponding play time of target medium segment finish.

System receives and includes the playback request of " the small icon function of testing right side ", and identifies that the playback is asked It asks to be played back to the content after target medium segment using the corresponding target medium segment of target text segment as starting point Playback request, according to the corresponding relationship saved between text segment and media fragment, finds target text in media file library The corresponding target medium segment of segment " the small icon function of testing right side ".Next, being saved according in media file library Play time of the media fragment in multimedia file, i.e. starting playing time and end of the media fragment in multimedia file Only playing time obtains the play time of target text segment " the small icon function of testing right side ", gets target text The play time of word slice section is 1 second to 4 seconds, i.e. the starting of target text segment " the small icon function of testing right side " plays Moment is 1 second, and terminating playing time is 4 seconds.

According to the play time saved in media file library, target medium segment and play time are obtained in target matchmaker All media fragments after termination playing time 4 seconds of body segment obtain the media fragment that play time is 4 seconds to 5 seconds, broadcast Putting the time is the media fragment of 5 seconds to 8 seconds media fragments and other play times after 4 seconds, that is, gets target text The corresponding target medium segment of word slice section " the small icon function of testing right side ", the corresponding matchmaker of text segment " too small " Body segment, the media fragments such as corresponding media fragment of text segment " perhaps, what in the event of that ".Playing target It is first 4 seconds to 5 seconds to play time after the corresponding target medium segment of text segment " the small icon function of testing right side " Media fragment play out, i.e., first play text segment " too small " corresponding media fragment, be 5 seconds to play time To 8 seconds media fragments, i.e., the corresponding media fragment of text segment " perhaps, what in the event of that " was played again, according to Play time successively plays out the media fragment got.

It can also be with when target text segment " the small icon function of testing right side " corresponding target medium segment is broadcast Difference between degree of putting into, and termination playing time 4 seconds of the target medium segment, when being less than a certain preset threshold, in media In library, the adjacent media fragment of play time play time corresponding with target medium segment is searched, that is, searches starting and broadcasts The media fragment constantly for 4 seconds is put, the play time for finding the corresponding media fragment of text segment " too small " is 4 seconds to 5 Second, the corresponding media fragment of text segment " too small " is buffered；To the end of target medium segment plays, directly play The corresponding media fragment of text segment " too small "；Correspondingly, to the corresponding media fragment of text segment " too small " Difference between playback progress, and termination playing time 5 seconds of the media fragment when being less than above-mentioned preset threshold, then is obtained and is broadcast Time and the adjacent media fragment of text segment " too small " corresponding media fragment are put, that is, searching starting playing time is 5 Second media fragment, the play time for finding the corresponding media fragment of text segment " perhaps, what in the event of that " is 5 Second by 8 seconds, the corresponding media fragment of text segment " perhaps, what in the event of that " is buffered, and in letter plate After the corresponding media fragment of section " too small " finishes, directly broadcasting text segment is " perhaps, assorted in the event of that " corresponding media fragment；And so on, media fragment of the play time after 4 seconds is successively played out, until user Triggering stops all media fragments of broadcasting or play time after 4 seconds and finishes.

In addition, in aforementioned four example provided by the present application, when establishing media file library, letter plate can also be established Corresponding relationship between section and character types records marked off media fragment that is, when dividing to multimedia file Corresponding character types, and the media fragment is being subjected to speech recognition, after obtaining text segment, it is corresponding to establish the media fragment Character types and text segment between corresponding relationship, and be stored in media file library.Same character types will be corresponded to Text segment stored.When selecting a certain character types as target roles type, correspondingly, the target angle will be shown The corresponding text set of segments of color type.
